Honestly can't believe all of what these modders can achieve in AC, I'm amazed everytime a new update comes in! Unbelievable that this 7+ year old game is part of my weekly simroutine and that I still find new things to do in it everytime! Thanks for the showcase and very clear explanation random callsign, great video as always!

[@fns58]

Man I truly feel bad for not supporting this guy, will probably support him for a few months. He's one of the main reasons AC is still relevant as of today, and at such level.

[@user-zc9zt2vl5s]

totally agree, him and Peter Boerse the developer of SOL are what makes AC what it is today!

[@aaroncumberland7625]

Dude probably bought a real Ferrari from the profits he's making. Realize that he's taking in over $250,000 a year from Patreon alone right now.

[@DE_JOTT]

The ONE thing I would really like in AC is an updated tyre model to get better behaviour over kerbs and bumps, like they did for ACC at some point - still, the progress this game has made thanks to the modding community is insane, thanks to all of them!

[@jackdyson5670]

I don't think that's possible from what I know thus far mate ; The code base uses one contact point over the contact patch to sample the tyre dynamics and ACC has 5. ACC did that to specifically solve this issue. There is a very good Kunos article about this, I just can't find the link right now :(

[@DE_JOTT]

@@jackdyson5670 I know they did and I remember that article. Wasn't sure how they implemented that though, but if you can do that for ACC you surely can for AC, no?

[@jackdyson5670]

@@DE_JOTT :) Cheers for the reply mate, sure it can be done, that's what ACC physics is, AC + enhancement take away proper weight transfer - from what I know about contact patches it would have to be a method in the tyre object model deep in the vehicle dynamics heirarchy - if you used 5 spatial points then each point would presumably sample local physics and develop an overall "grip tensor" that represents the state of the contact patch at time t. This is fed into the now 5 slots of the differential time propagator to work out the new total tyre force (whether the tyre lets go or not). So from my limited speculation - I would guess its deep inside the core c++ dll of the game which Kunos won't allow access to ... 🤔

[@DE_JOTT]

@@jackdyson5670 The 5 points where the tyre is in contact (or isn't) I am familiar with, easy enough to understand why that works better and since I drove ACC from the very first day of early access I know how much of an improvement it was. The rest and how exactly one would do this in AC goes over my head, I'm afraid, but thamk you for attempting an explanation :D Thing is, since Ferrari have decided to use AC for e-sports and ACC is running well maybe kunos could spend 1 or 2 devs just for a while to do this - would make the game even better, keep it alive...

[@unknownvinnumber]

Indicating while changing lanes, nice haha!

[@randomcallsign]

possible due to CSP :D

[@toddwasson3355]

I've been writing physics engines like this for a long time and am familiar with the problem having encountered it in my own work. I don't know if it's possible for a modder to do this, but seeing as somebody was able to change it from floats to doubles, maybe it's possible: The trick is to reset positions back to the origin occasionally. I.e., once the distance from the car to world space 0,0,0 (the origin) > some value, you shift the car back to the origin and shift all the other objects by that same offset. Presto, no matter how far away you get or how big the map is, the physics won't get wonky. You don't even need the doubles anymore. Do that and your size limitations will be gone forever.

[@ICKY427]

holy crap. this is HUGE. like really huge. the more i read up on the issue the more i found the general consensus was that it could NOT be fixed, it just wasnt something that could be changed without literally rewriting the game from scratch. it seems Ilja is once again done what they said was impossible. just seeing how little your car was shaking at the far end of srp looks like its a MASSIVE improvement. i cant wait to try it out. now im torn between this ac update and the elite dangerous odyssey alpha haha

[@henrik1743]

I am 24 years old and Ilja is the first and only guy I have paid on patreon, he's worth every penny for fixing these things and the rain mods

[@jackdyson5670]

I think it's 1 dollar a month mate. Ilja is just fantastic isn't he? I heard somewhere that Kunos are looking into his stuff for AC 2 actually as well as dumping Unreal engine. Like many here I think they should consider taking him onboard if he agrees. And double precision will use more memory and CPU for common arithmetic. The GPU matrix multiplies and CPU work would presumably therefore hit your FPS as you noticed. That's why doubles are always last on the list as a tool for simming anyway. Too expensive. Great video again mate - many thanks!

AC will outlive some Sim that will come out in 2025. Reverse engineering of the physics engine and we'll get ACC physics. I can see this happening at least in some capacity. If more devs come together because reverse engineering is slow, very slow, and you have to test each/one "piece" at a time you think you changed for the better.

On the flipside, how much do you play this a month? I easily play AC 5 hours a week. Your comment would hold merit if they were already paid a monthly salary, but is it 'nuts' to ask for a donation to have the newest features the fastest when these people spend who knows how many hours working on this? Hell look at what they all released for free in the first place. I support all the amazing work these people put into supporting this title. You gotta vote with your wallet, 60 bucks to some triple A product that is ditched a year later, going into the pockets of shareholder/big corperations, where developers are already paid a monthly salary and routinely overworked. Or 70 bucks a year towards passionate people who care about the community and work voluntarily to keep supporting a title. You speak of them like it's somehow thier job to fix anything. I know where my money will go, on principle alone, ofcourse you're free to buy or not buy whatever you want, but to call it ridiculous when you don't even play the game...

You can change your payment to 1$ or 2€ per month and you can easily cancel your monthly payment when desired. Yes, you can always pay for one month and get all the updates you want.
