Here's Why You Suck At Forza Horizon 5 (Pay2Win Physics)

[@seP4]

Forgot to mention: The game speed is not slowed down alongside the timer. We looked at other runs from the “world record holder” mentioned in this video and some of them are actually faster than humanly possible. It is possible that some of the game physics are running faster than intended, giving him an even bigger advantage, but we are not 100% sure about this one and there are no reliable ways to test it. This is another thing for to investigate Correction At 4:28: That's 56 clean runs for 30fps

I actually really appreciate your effort in researching this. It’s weird because I had a gut feeling some things were off, like no matter how good I was or how perfect my timing when breaking on upcoming corners was the ghosts always were ahead of me. Seeing this kind of relaxes me and hopes this will eventually be fixed or acknowledged. I like how some one mentioned the ability to filter would be helpful.

[@itoaster]

At one point I know Forza (Motorsport, at least) ran a fixed 180hz physics refresh rate, and also most major racing sim titles run fixed physics refresh rates as well. I suspect this is caused here because at some point, Forza switched to tying the physics refresh to your framerate - or may do this in specifically Horizon titles. It still doesn’t explain the game timer issues, but it would at least explain the physics issues between 30 and 60 fps locks.

[@chillaxTF]

Why would they make that change? Seems like a massive downgrade

[@DigitalJedi]

@ryan It's easier to run at an acceptable rate vs an independent physics engine. In the 108hz physics example, super slow hardware that can't keep a consistent 180hz tick rate will cause the game to speed up and slow down. But, in an fps based physics system, the slowdowns are compensated for by having more time between physics tick, by having a frame drop.

[@Hellothere-by4ye]

You know that's some GTA V level programming there. That game has exactly same problem in online mode. Framerate gives more speed, suspension works weirdly and it also gives you speed boost which we call kerb boosting. Basically exploiting physics to gain more speed by clipping methods like changing rims. Anyone interested can check broughy's fact check videos.

[@AYW07]

In "Beetle Adventure Racing" Physics also change with different frame rates. PAL N64 runs in 50 fps where american version N64 runs in 60 fps. The console calculates the cars position every frame. Means that if the car experiences any changes in (the track) directions, it calculates whether it gets closer to the ground or further away. Resulting in a change of the cars direction, or not. For example if your going up a ramp, your car wants go into the ground. The cars velocity and direction is always the result of the calculation from the last frame and the players input ofc. So going up a ramp means that the cars calculated direction and the direction of the street do not match, resulting in compression of the springs and a change in direction and velocitiy for the next frame. Long story short. In 60 fps it does that progress more smoothly than in the 50 fps version, resulting in the cars physics and behaviour beeing more volatile. It is more likely that strange things happen with lower fps. Maybe thats whats going on here

[@kingcars]

I know you mention that it doesn't affect online races, but I can't even count the number of times I've clearly beaten someone to the finish line, only for the game to register them as finishing ahead of me. It was a big issue in FH4 as well. I have a sneaking suspicion that these issues are related.

[@robertkennedy9369]

It happened to me as well.

[@Shinu.oka.]

Thats typically called "xboxing". It happens because xbox players start ever so slightly later than pc players by maybe 0.050-0.100 of a second. To counter this the game subtracts that time from the finish time at the end to balance out the minor time loss at the start. This is likely fps based as its not unknown for this to occur for some pc players too but it is far less frequent.

[@Jlewismedia]

It is the physics tick speed which has numerous different names. Almost every modern game with any sort of collision has separate tick speeds, it's usually locked to a lower number like 40-60fps which has very little deviation in consistency and they use something called DeltaTime which is an approximation of the time between two frames to do t mathematics which is everything from the timer to the rate of force dispersion in suspension. However the larger the difference tick consistency the more deviation. Im not sure exactly why but I suspect Forza's default tick rate (for menu logic and what not) is somewhat tied into the physics system so unstable normal tickrate has an impact on the physics tickrate. I beleive it might have something to do with performance in that regard or it could be a legacy issue with their engine being built for 30fps on older consoles. That's why many games still have a fps cap on consoles so that the gameplay is consistent especially in physics based games. The non determinism you spoke about is true, it can be caused by another computer science term called "floating point errors" where a number is too large or small for the computers 32bit floats to encapsule so numbers get trimmed. If the framerate is higher or lower it can change what values are in certain equations and sometimes they can get chopped off, only causes minor mis-calculations in equations but when the equations go from like millimetres surface are to newton meters of force created by downforce you could be a whole int value out, have that happen a bunch of times and you get some silly physics or silly timers. en.wikipedia.org/wiki/Delta_timing en.wikipedia.org/wiki/Floating-point_error_mitigation en.wikipedia.org/wiki/Speedrunning

[@edgesplitmusic]

Having worked with lots of physics simulation programming I think i could provide some insight into possible causes. Things like suspension, tire friction modelling, aerodynamics simulation are bound to be error prone when handled incorrectly. Time interval between the frames of simulation can change the outcome. In the case of the suspension - for example slower simulation rate may cause springs to get more compressed under changes of load on the car (like seen in the video with the cliiping on the loop) because there is more time between the cause (compression of the spring) and effect (spring force and damping acting on the car). Same can happen with tire friction but the time precision errors are usually more pronounced because the response in non-linear. You can search for tire friction curves if you want to see how they look. This can cause a tire to spin further before the forces are applied, therefore making it possible to spin faster than it should and getting less friction as a result. If the simulation results are dependent on the simulation framerate, an unstable simulation framerate will make them more random/non deterministic. Possible solutions to these problems are: running the simulation at a (edit: stable) rate independent of the graphics fps (commonly used, not idea why it's not used in fh5) and numerical integration or running critical parts of the simulation multiple times per frame internally to minimize the errors. It would be interesting to see you test the friction with different fps. Maybe some powerful cars with a lot with wheelspin? No idea about the possible cause of the timer thing, but someone definitely did a shitty job with that.

They did have framerate tied to the physics, but in specific sets of framerates. They did try to solve the issue but they didn't realise that computer can't do math.

[@kmemz]

My conclusion from the suspension graphs; the physics updates are fully tied to the framerate. Reducing the framerate reduces the amount of updates the suspension model recieves. The lack of updates means that the suspension will behave less consistently due to important details of the track not being reflected in it. At the same time, while higher framerates seem to help with consistency, I'm sure there is a point in the hundreds of frames per second, where the suspension will update so quickly that it may begin to behave erratically. And because the update rate improves consistency, the erratic behavior may also be consistent.

another idea for testing this: make an autohotkey script (or similar recorded inputs) with set steering and throttle/brake inputs, then let that run on 2 different machines. When overlaying the two videos, it should show one of them with synchronous inputs, but different positions on the course, leading to inputs that are desychronized from the track leading to a wipeout.

I'm a game dev myself, and some physics engines are frame rate dependent, for example in Zelda TOTK, when using hacks to run the game at 60fps instead of 30, objects feel very heavy because they fall twice as fast. Since this game normally doesn't have a locked frame rate, they most likely implemented something called delta time which speeds up or slows down the game depending on the frame rate, so the game doesn't run half the speed at 30fps which wouldn't make sense at all. Delta time is used in practically any modern video game and is therefore nothing special. It's difficult to get right though, I recommend the video about it by Jonas Tyroller. If you don't get it right, players with higher fps have a higher game speed. Not really noticeable but when there is a timer, it suddenly does become noticeable. So that kinda explains the timer and the physics.

See: Quake 3 Arena Rocket Jumping and FPS. This is what happens when in engine timing, that also controls things like physics polling rates, and the in game clock, are intrinsically locked to frame rates. You end up bending the rules of how the math is done by cheating the frame rate. This has been an issue on Q3A for physics, as previously mentioned, and also for leaderboards on Sega Rally 2, where higher uncapped frame rate would also cheat the clock to run slower, and make the "wall tap" braking technique for hairpins much easier, as it also cheated the physics engine, and made the collision and accompanying speed drop less severe, the higher the FPS was. Which eventually led to all PC Sega Rally 2 times being rejected.

[@darvonmitsumura536]

I know it has been a year since this post, but I would like to clarify that Q3A actually did create a work around for this behavior called pmove_fixed. It is a server side setting that was designed to help normalize player movement by making it so that everyone would be running at 125 fps regardless of their own fps settings. Not only did this prevent stupid differences in how gravity affected your jumps, but it also helped with making map strafing easier to handle for those tricky jump pad courses (giving the right amount of speed per pad instead of often falling painfully short as pad distances increased).

This can effect a lot of games and is down to time delta not being accurate enough. In multiplayer the *tick* for physics takes place on the server and so it should be more consistent in terms of timing. In singleplayer the "tick" is on the players CPU. If there are 60 ticks in 1 second and the time between each tick is some number, e.g. 0.000230 but the CPU depending on architecture and also lots of other factors can reduce the accuracy of this number (in other words, the computer isn't fast/good enough to know the smallest amount of times possible in reality, i.e. picoseconds) After the 5 ticks are added up discrepancies can appear, for example: Tick 1. 0ms Tick 2. 0.0020000032ms Tick 2. 0.0010000032ms Tick 2. 0.0030000032ms Tick 2. 0.020000032ms If this were handled by a a computer, it may not have this degree of accuracy so lets round it up. Tick 1. 0ms Tick 2. 0.00200000ms Tick 2. 0.00100000ms Tick 2. 0.00300000ms Tick 2. 0.0200000ms As we can see now, we missed all those 0.000000032ms at the end of the number... And that really matters. All of this adds up over many ticks. A good way to think about Ticks is FPS, its not always the case, but you could say for every frame, there is one tick. 30 FPS means much less numbers, also rounded innacurately, therefore producing worse results 60 FPS means trying to do 60 ticks inside 1 second, rather than 30. Well if we imagine if the CPU can handle 60 ticks, it probably has less of a time delta between each ticks. Because its a better CPU. 30 FPS means trying to do 30 ticks inside 1 second, which means if the CPU is running fast, or the tick is running faster than 1 per frame, the maths get's even more out of whack. For example your game may be 30 fps, but your tick is 60 ticks per second. Now the maths to calculate the time between frames is much more different, we're now factoring the fact 2 ticks occur per frame, and so we once again destroy the original "1 tick per frame" ideal, and end up with some bodge maths. As game devs we use a simple math trick to resolve the issue, which when we're talking on the "seconds" time scale is fine. But anything sub 1 second, we all accept we lose the accuracy. Here is the math: 1 Second is equal to Desired FPS/TicksPerFrame - Time since last frame Example: Desired FPS / Ticks per frame - Time since last trick (or frame) 60 / 60 - 0.0002ms

[@Revelatus]

If I had to guess, it seems like it’s in-part a problem with interpolation, and the frequency of physics updates. It seems from the video like collision + physics updates are only applied when a frame is rendered. If you had a mod to prevent the rendering of the game without triggering some sort of lag compensation system (if one exists), I have a feeling the cars may start “driving” through walls. Video games these days are meant to work at varying framerates in a roughly consistent manner. However, it can be difficult to handle collision updates in these non-deterministic situations - almost as if the collision detection somehow relies on the frame that was previously rendered to determine if a collision happened rather than calculating the physical interpolation based on a frame or two ahead. As such, it makes sense in the loop example that the car clips into the floor more at lower frame rates because the game has to “catch up” more slightly more to visually reflect the velocity applied from the previously-rendered frame. As easy as it can be to put our conspiracy hats on, as a developer of other games and systems I believe this “pay2win” aspect that appears here is very much not an intentional design element, but rather just an unfortunate side-effect of the way physics updates are handled. I think that one of the few ways to level the playing field more in ‘competitive’ environment would be to limit physics to a time-based system. Ex - when the in-game timer passes certain thresholds, one or more physics updates are applied, but not so much that it causes the game to lag on older hardware. This would, however, cause a VERY SMALL visual desync in the moment to moment gameplay that can cause things to feel _extremely_ different on newer hardware. It’s a biiig balancing act. If ya wanna truly fix things, fix the real-world economy lol

I have something to add about the suspension clipping in the loop. Two of my friends playing at uncapped FPS always wondered how I get less clipping when playing in the Hot Wheels world. I play at capped 72 fps. When my friends also tried capping their fps to 72 they stated getting significantly less clipping than before. So it seems like at high enough fps you start getting disadvantages again.

[@KvltKommando]

well fuck this series then, I only care about playing at 120fps or higher, 72 fps looks so bad on an 144hz monitor. If I want to play a low FPS game I'll choose one that at least maintains a stable physics like Ridge Racer R4 on playstation emulator

[@SRS13Rastus]

I'd guess it's a rounding issue 60fps = 1 frame every 16.6(recurring)ms, 30 = 33.3(recurring)ms, 120 = 8.3(recurring)ms with the fps rate on console locked to maintain 60fps then it's always rounded up. the others get rounded down. Testing at performance mode vs quality mode on console might well highlight this. IDK what the server polling rate is but if it's at the millisecond level then 60fps would become 17ms, 30fps would be 33ms. 2 frames at 60fps would then work out at 34ms, a 1ms discrepancy 30 times every second. 60 seconds = 60,000ms, 60,000 / 17 = 3,529.411764705882 frames created per minute. 60,000 / 33 = 1,818.181818181818 frame created per minute. 30fps is exactly half of 60 fps but if you divide 3,529.411764705882 by 2 you get 1,764.705882352941. Here's where it gets interesting... divide 1,818.181818181818 by 1,764.705882352941 and you get 1.03030303030303 multiply this by 100 and you get 103.030303030303 a 3% difference between 30fps and 60fps over just 60 seconds. It'd be almost impossible for 2 different players to do EXACTLY the same lap, if you COULD you'd probably see exactly a 3% time discrepancy. Roughly 1.77 seconds behind or 1.81s ahead depending on viewing at 60 or 30fps. In the loop section? Again it'd be nigh on impossible to rewind to exactly the same ms every single time you COULD be upto 0.5ms either side and be totally unaware of it, add in the 17 and 33ms frame time and going frame by frame the accuracy error is copounded, therefore you'd see the changes shown in the telemetry traces, some would bottom out others wouldn't...

I have an educated guess on why cars are faster at higher frame rates. It's jerk, or the change in acceleration. The jerk for each car will be a fixed value (lets say J=1 for now). That means that the acceleration for each car will be a a function that approaches the controller value depending on the jerk. In a perfect world, the velocity at each moment would represent the area under the curve, but since the physics engine measured the jerk and acceleration each frame, it looks like those Riemann sums you did in highschool. The more rectangles you add, the closer the area approaches the true value, so if you double the sampling rate you will get a closer answer to the true velocity of your car. One way to fix this is for the PC to do all its physics calculations every other frame to match 30 fps.

[@Hugueta1503]

Your study of this situation in the game is very important!

[@WunderWulfe]

in some cases the physics problem is "solved" by using fixed physics timesteps that may result in physics that runs at much higher or lower tick rates than the framerate, either asynchronously (runs independent of rendering) or synchronously (runs X physics steps on each frame) in order to achieve more accurate and consistent physics, but even then floating point arithmetic may sometimes result in a buildup of small inaccuracies or changes that can make an otherwise "similar enough" run have a different outcome

[@mcn7958]

I have noticed the frame affects something very early. when playing 10 skill points blueprint, such as 139 710 733, the lower frame makes you run faster. Using X seseto fe, 41 fps → about 25.4s，83 fps → about26.3s. And sometimes, the speed just ignores obstacles. You have the skill points but just like going through the obstacles, so it will be under 23s. But when you go faster, you will get less exp. using 165fps, about 3733 3961 4000 exp per round, 30 fps would be 32xx exp. It seems like because one frame cannot handle more than 2 times collisions. For example, if the speed is enough to hit 61 obstacles in 60s, but you only have 60fps, there will be at least one frame that has 2 or more than 2 collisions. It may only cause one slowdown. So lower fps let you ignore more slowdown by collisions. And I think I played afk more than all players in fh5, my id : nmcleo, I even go afk for online racing. And now I am on the top 25 of the exp board. I spent a lot of time on tuning for afk, so I have tried what is the best fps for afk. Higher fps have advantages in most maps. But the game is more likely to crash with the unlocked frame, so I am using 83fps. With NV gpu + over 5ghz cpu, using nvidia profile inspector, you can run fh5 over 200 fps. Just like how some people play pubg.

It's not just forza with this problem, other games have it to, but in different ways. One being Roblox where in some, or most games, the physics act better with higher frames. A game or two to test this on would be Dawn Of Aurora and Phantom Forces. For DoA, look how vehicles drive with higher vs lower frames and how they react to the terrain. For Phantom Forces, look how the gun recoils. It's less noticeable as FPS increases, but there is a difference. Usually when recoil starts acting wild is at lower frames below about 20-30.

Gravity is often tied to fps in first-person shooters. I think a simple way to make it make sense is that a faster device doesn't have to skip any calculations to meet a performance target. Hence why with more fps the suspension values have time to go through more position checks, returning more values, smoothing out the transitions.

60 fps causes less loop clipping because the physics engine has double the amount of frames to calculate physics iterations which can only happen based on the amount of frames rendered in the simulation. Slow the game engine down with uncapped framerate and you'll notice almost zero loop clipping at all because the game has all the time it needs to calculate the suspension travel. This is true in a significant amount of games, but I've never personally witnessed it in a racing game, especially one with a competitive scene. Another example of this is can be seen in BeamNG Drive, where the physics calculations on the crashes get significantly more 'approximate' the faster gamespeed and lower the FPS. Slow the gamespeed down significantly, which then increases the FPS simultaneously, and you'll have far more accurate crash physics calculations per frame.

[@Aisaaax]

It's a very common bug in videogame engines. Basically it is a rounding error. The numbers in your PC re represented by a finite number of bits, usually 32. When you divide something unevenly, on paper you often generate an imfinite decimal nimber. Think of Pi for example - it never ends. But your PC can't do that - it can only calculate numbers up to a certain measure of precision, after which it will discard everything else. That precision is usually more than enough for any error to be absolutely negligable and unnoticeable. But sometimes, like here, you may notice it. Imagine if a timer is calculated every frame. If you run at 60 FPS, you add 1/60th of a second every frame. If you are at 120 fps - 1/120th. But those fractions only look neat if they are represented as a fraction. If you show them as a decimal, the story is different. 1/60 = 0.01666666(6) 1/120 = 0.0083333(3) They stretch on infinitely to the right. Now let's cut them! The PC is a bit smarter than what I'm gonna show here, and much more precise, but the gist of the problem is the same. I will just drop everything after 5th decimal place,and then round the remainder: 0.01666666... = 0.0167 0.00833333... = 0.0083 And... Uh-oh, we were forced to round up on the first number, but we are rounding down on the second. So at 60 fps we are adding slightly more to the timer than necessary, and on 120 fps we are adding slightly less. I should note that depending on calculations and exact fps you can see the reverse as well, so it is never a clearcut "more fps = better timer". Unfortunately, I should note that the only way to get rid of this error is to run your timer in a frame-locked thread or to compare it with system time or something. And even then you will get discrepancies on 2 different machines. This is impossible to fix completely simply due to how computer maths works.

[@dekoldrick]

[@julientripon1092]

Really interesting ! I immediatly think of "simulation" : Physics in a car game is always simulated. While in the real world, the compression of the spring is continuous, in a simulation, it is discrete. In mathematics, something continuous is when all values of times (in this example) are available. Something discrete is only "step-by-step". For example, y=x^2 is a continuous function, but Fibonacci sequence is discrete (1, 1, 2, 3, 5 etc, but nothing between 3 and 5). For a 30fps rate, values are calculated every 0.0333.. seconds and for 60fps, it's every 0.0166... seconds. It seems a detail, but for a simulation it highly important. Due to the interaction between all values (with derivatives, primitives etc), calculations for continuous in live are quite impossible, because there far too massive. So physicists and developers use simplified discrete calculations. Far more simple, far faster, but more or less approximative. So approximate that for the same starting value, the t=0.003 value at 30 fps and at 60 fps will not longer be exactly the same, simply because at 60 fps there was an intermediate value. On the contrary, for a rendering scene in 3d, you can use longer and more precise calculations. That's why rendering in a 3d software takes so long.

Nice. Looks like physics are tied to frametimes in some way. Seems that in the loop test suspension is reacting slower in 30 than 60 fps, which in some situation will cause clipping. Possibly frame frequency was not enough for game to perform bounce back of the suspension, causing it to clip eventually. I do wonder if this glitched times were however done with limited fps or not. If not maybe physics engine couldn't keep up and caused game to go out of sync between physics and frames?

[@MontagoDK]

The reason why framerate interfere with physics is because the simulation rate is frame bound. An object moves distance pr time unit , then you calculate 'whats up' and fix errors according to the physics (intersections ) .. if objects are intersected , you push them back and continue with the simulation. This is the simple version of physics calculations. The more appropriate is to use Euclid's which do calculations BEFORE moving the objects. And therefore doesn't need to fix intersections. .. but Euclid is harder math and therefore not always used. When you only have 30fps, objects can potentially move further into each other and require bigger fixes. Thereby potentially make you go faster or slower. Having 100fps on the other hand creates a finer gradient of physics with smaller fixes. Which again can improve or slower your driving speed.

[@alaniumacity4375]

As a person who knows a thing or two about game development, I have no idea what they can do to fix it. But here is a possible reason why this could be happening: Inaccurate time interpolation. All games run on the same principle: perpetually running the required code, over and over again. Some games update each frame, which causes them to run in slow motion at lower frame rates, and others anticipate what will happen in the same period of time at different frame rates. If a game doesn't run at it's intended perfect frame rate (usually 60 or higher), then it tries calculating ahead to save on resources and not cause itself to have to run slower. Most AAA games use this method. It's beneficial for the player, but due to these pre-calculations being slightly off, it might skip an update or two, and in the end that adds up.

[@theshawnmccown]

This is true for all games. In sim racing titles like Raceroom, AM2, I racing, etc., you can have a screen that only does 60fps but the game does 90 or 120 fps with a frame viewer. With each fps all of the inputs and physics is updated and calculated. So, 120 fps is going to be more fluid and accurate in it's handling even though the screen is updating at 60 fps. There was a mod that allowed one of the Transformers games to run at 60fps. The catch was the physics were a little off because the engine was built around 30 updates a second.

F1 2018 also had a bug where tyre cool down rate was tied to FPS aswell. Meaning higher FPS = faster cooldown.

[@Wourghk]

This happens because fixed timestep (and thus physics computation) is locked to the target framerate, but not framerate-dependent. It's not the timer running slower, but rather the timer being updated more frequently without as much interpolation between samples. In other words, your timer is a higher resolution at a higher framerate, which is a more accurate representation of your lap time. Anyone running on inferior hardware is actually sandbagging themselves with interpolation errors. In multiplayer, everyone's clock is synchronized to the least frequent timestep possible to ensure that any potential low-spec users can actually join and play. This means all multiplayer matches are fair in regards to clock speed and your hardware won't give you an advantage in that regard. Coincidentally, it also means handling characteristics and lap times in multiplayer are a bit less accurate in general.

Shit like this, and how brutally stupid a lot of the meta builds are is what made me lose interest in FH5 after putting quite a bit of time into it. FH tries to be this weird middle ground in terms of realism and arcade hilariousness and that just breaks it IMO. I've had a lot of fun TBF, and really enjoyed building and tuning cars to a high level and taking on online races. This just gets shit on by stupid meta builds, glitches and half assed development though. It really is a bummer when one has built up their favorite car, spent ages tuning it to be a winner in its class, but then has to resign their mindset to "winning the non-meta class" in online races. Drifting was fun, I got involved in some online communities that did great, realistic driving and it was the most fun I'd had in FH5. It's a real letdown how half assed the competitive component of drifting is. If a dozen cheap mobile games can implement more realistic drift scoring (zones, clipping points and proximity), why cant PG? It's kind of interest specific I know, but really highlights how much of a lazy, child market cash grab FH has become. Mobile games do most of it's elements better. Just this morning I uninstalled FH5 after playing it since launch and change my racing game library to two polar opposites that don't try to split the genre and come out half assed. I'm happily playing Unbound for fun and really enjoying the style and story, and getting into Assetto drifting now that people have figured out controller support while I save for a wheel.

This is a universal issue with render engines. Faster number crunching equals faster results. Combine better hardware with less computational load, _everything_ runs faster (clock speeds take on a double meaning here shortly). I forget the title where this became very evident, but well over a decade now, it was observed in an online competitive looter shooter with very large maps and no fast travel that looking down while running had a dramatic increase on how fast your character could run. Less information was being thrown into the GPU for rendering, increasing not only the overall FPS return, but also the speed at which it is processed. So the test was two characters geared up identically would run 10 miles across the map, one looking only at the ground, the other normal. The character who looked only at the ground received an FPS bump and finished Minutes before the other character.

I recently doing a real time rendering job for an earthquake simulation in UE. The only way to get a precise calculation is by NOT going real time. Dividing and calculating 1 frame 20 times will get you more accurate physics. But it will slow down your rendering by 20 times. that's what basically what's substeps does. So if you're using a slow PC, the calculation of 1 frame could cut short, and it goes "fuck it, just move to the next frame" and you get a very bad incomplete calculation. This could lead to understeering a lot. In other kinds of games, say fps for example, where you sometimes see boxes or ragdoll goes crazy, is because it had 1 bad frame, and it intersects with the floor or other rigid bodies, and the next frame goes "that's not supposed to be in here" and tries to push it back out, which leads to the boxes launches at high speed.

3:24 or maybe after going 100 laps you finally got to know the track and started getting better times.

Yeah wtf was his thought process on that...

[@zarodkiewicz]

I like that you don't make a big thing of some of the glitches and malfunctions. Some other youtubers would name their video "this is unacceptable, outrageous". Good man.

this game's physics became very forgiving edit: i would be laughing if bro still believes that mars is a cheater

[@AEMNinja98]

No not at all they keep making it worse and worse

[@damnsonalabanca420]

FH4 physics so much more fun

[@djungelskog2654]

Remember when racing games had clock brands as sponsors? This is the reason they used to

amazing job, good work m8!

[@fosterengelman7656]

Thank you for putting in the work to critique this series of games. Forza had such a great start in both motorsports and Horizon. I'm at the point where I won't be buying either of the new offerings. Given the bugs, community issues, and downright laziness that I've noticed, in addition to your critiques, there are far better titles for the money.

On my first watch here, the bit about 30fps vs 60fps and its effect on lap times seems to rest on some flimsy logic. If you just got done running 100 laps on the same track in the same car, you’ve gotten more and more familiar with both the track and how to maneuver around it with that particular setup. It’s not at all unreasonable to imagine that you’re genuinely just doing better and are able to meet the time much more quickly and consistently with all that practice - especially if you’re now receiving visual updates twice as often as on your first 100 attempts. Those are both pretty huge advantages.

[@Vester77]

So if I play at 165fps it’s even bigger advantage lol

[@rakaneko4229]

I jave a lil bit knowledge on this, There's 2 type of physics: 1.one that tied to fix fps, so this mean no matter how many fps or refresh rate, the input will still record in (for example, is 60fps). 2.type of physics or input that depends on how many fps the hardware can produce(imagine doing time attack but the timer just ignoring the loading screen), like some games where u can slash more by using higher fps which give u some advantage. Perhaps this is a hardware issue where the game slows down a bit to load ingame data

This happens in every game with a time and therefore physics altering mechanic....like rewind in driving games or V.A.T.S. in Fallout 4. Once the system was ported to Fallout 76, players found those with unlimited frame rates could run faster than people who didn't as physics was tied to framerate. Add to that Horizon was the fun-park-not-seriuz-candy-racer compared to the straight-faces-stopwatch of Forza Motorsport 7 (despite it having a rewind mechanic too).

Hate those forced subtitles. You're aware YT has built in CC support, right? People who need them can turn them on, those who get easily distracted by subtitles and stop listening can keep them off. Win win.
