I recently upgraded my cpu to a 5800x3d from 3950x using a 3090 on both CPU’s. With quest 3 on ams2 I can’t even run at 72hz anymore. I had a locked 72hz previously. I have no idea what’s going on here

If i want play iracing in 3 screen 2k is 4070i is enough?

Would the triple 4k translate into VR performance? Asking because VR would be around 2*4k at 72/90fps ideal performance. Just wondering how the two 4080 and 7900xtx would fare

Thanks to the algo, I haven't even looking for GPU content for a few weeks, but here I am. I need a new laptop and don't have desktop. Never had gaming spec stuff. My next monitor will need to be the 57" dual 4K Samsung. It's so much more affordable than the watches and cars I lust for... What laptop specs might run dual 4K at 100 FPS in iracing at a detail level with 4K? Else, how might it look dialed down to 1440P leaving it to the monitor to scale up dumbly or cleverly? I don't know how clever they've made the monitor, but Samsung does have upscaling stuff in-house.

i love finding exactly what im looking for:) I got a PC RD 7900xtx and thinking of switching to a 4080 super. Thank you!

This is the first time I saw somebody talking the science diference between flat screens and VR regards to hertz and fps relationship. I made a video about Flight simulators taking exactly the same approach named "X-Plane 12 - The VR BIBLE - for Quest 3 and Quest 2" Thanks for sharing that amount of knowledge This channel really deserve more views

i need u to upgrade your vr headset to like psvr 2 or reveb g2 at minimum

You can't imagine how these videos help us to decide what to do with our money!

120hz? No dice without upgrading to a new platform from my 5800X. Thanks for the useful information.

Super video! I currently run 10600K on iRacing VR and it just isn't cutting it. Updating to 7800x3D

Very interesting. 1% lows are interesting. Very little difference unless you are on different architecture. A 12600k or even a 12400k would offer fantastic value with very little difference in 1% lows.

I'm really interested in AMS2, thanks for the benchmark, It would be great if you did a CPU benchmark like you did for ACC, I'm trying to check if my 10400f is holding me back.

I was looking for your other video comparing different games with the mid-level NVIDIA vs mid-level AMD as I remember some sims preferring one over the other. Like iRacing preferred AMD while ACC preferred NVIDIA. Was wondering if you plan to do a similar test for Le Mans Ultimate? Like if you mainly run LMU and want to get the best mid-level card for that sim are you better off going with an NVIDIA or AMD? For triples I was thinking, but would really be interested in whatever results. There's a couple funny things happening with like mirrors costing next to nothing, but going from Medium special effects to High bringing a system to it's knees.

I have now 11700 with 2x16gb@4000Mhz + 3080ti. Should i buy 7500f/7700/7800x3d(130$, 200$, 370$) for 3440x1440@144hz?

epic

I subbed!!

Exactly what I'm looking for. Keep the good work up! Subscribed.

Hi great video. Do you think a rtx 3070 can run triple 1440p 32 inch proper ?

MSI Afterburner has been causing stuttering for years, I surprised it took you this long to figure out, no offense. I used to be an avid user of MSI Afterburner, but after so many issues of it causing crashes in specific games, I started defaulting to have MSI Afterburner closed, and performance across all my games was way more stable.

precicely because of similar problems like this i have for years now, during normal gaming sessions, completely shut down all 3rd party tools & programs that i can. i do not need an overlay during gameplay at all!. the only time i use rtss / afterburner is for initial testing of settings of new games to find my preferred performance corridor to enjoy the gameplay. with a nice balance between fps and visual quality.

How did you connect the 7900xtx to 3 monitors? Specifically the USBc. Did you use a usbc to DP or hdmi cable?

This is so helpful. I have a 4070 super and an i4700k and my frames are struggling. This confirms I really need a new CPU like, yesterday, for my triple 1440 setup

You are one of a few people who know what you are talking about. Thank you. Let me add. My intensive experience is also frustrating. The complexity is even greater as VR performance varies per track, and the biggest problem is consistency. In my VR quest 3, some tracks are awesome, but at one turn, I get that annoying stuttering. My conclusion is that with a less perfect setup, it is kind of too hard to achieve a good VR experience. Lowering settings does not eliminate issues but just lowers them a little. You need a 4090, which I have, and the fastest CPU available with wifi 6e .... to have a near-optimal experience. VR is still a way from being perfect. Let's not forget that iRacing may need to optimize some of the tracks for VR, especially during fog and rain. My experience is the best VR projection software is Steam, but it requires a lot of CPU power. Note that Steam shines, especially with openXR. Still, the best for iRacing is the quest link cable, with OpenXR, which provides the lowest latency. Once I upgrade my CPU, I should use Quest link cable+, openXR toolkit, +Steam for projection, and iRacing, all on maxed-up settings. Yes, the experience is close to real driving 🚗. A small interesting observation is once latency is low, the control of the car becomes so amazing. That is what all top racers have, but they avoid mentioning it much. You feel immediately once the car oversteers, and correcting that becomes much easier. Sure not less than 120fps.

honestly this is the best video out there covering this topic. Thanks man you are a legend for all that work and effort that you put in here. im also running AMD Hardware 5800x3d and a XFX 6950XT and im struggleing with my FPS on triple 1440p. 3 Projection mode kost me around 20-35FPS but for me it is iorth because the emersion feels way better.

Will the RTX 4060TI on triples 1080p get good FPS

Precision X1 had hope, but then EVGA threw in the towel (sadge). What headset do you use?

afterburner or in german arschbrenner! .. 😂😂😂 is only useless old, nothing for oc or uv or optimizing, the best software is amd adrenaline! (joke) iam a linux gamer nohing goes over corectrl

i still have a 9700k with 3070ti. maybe i dont need to upgrade yet then.

I'm a firm believer in there are too many polling type events that are happening. IRQ events, so to speak. Too many of these interruption events are preventing computers from working as expected and to their potential.

Thanks for informing me that I can use 1440p triples instead of 1080p with my 5600x. Also, thank you for letting me know that the upgrade to the 5800x3d doesn't provide as much as I figured it would! Definitely considering an upgrade to one of the newer AM5 processors being released soon.

Great vid and defo helping this newb understand a bit more… currently on a build and have purchased a 7800xt 16gb gpu and wanting to pull the trigger on cpu with the 7600x being top of the list at $190 and if balling then the 7800x3d for $380. Problem is after seeing this vid the gains appear to be minimal for the extra cost or am I missing something? Thanks in advance 🙏

So what your saying is that I need to upgrade my cpu from ryzen 7 to threadripper 5995wx and gpu from 6750xt to 7900 xtx? Lol.

It would be awesome to do this for VR ❤😮

Hi, by any chance do you have a 4070 ti super too?😅

What's the performance difference with 4070 Super (I have) vs 7800XT (want to try) with 2k 32" triples, I gotta know?!

wtf with pedo mustache? u blind?

I get stuttering 24/7 at night Spa dry races even when FPS is 130, it’s really annoying and takes away the fun. When everything is butter smooth I forget that it’s a game but when stutters happen I say: Damn it’s obvious just a game. I’m not an expert regarding these things to find the cause but have Geforce experience running but it ran previous season also without any problem so don’t think that’s the issue. I think 99% it’s an iRacing problem with those latest updates you mentioned in the beginning of the vid…

Interesting... I struggled with stutters on a Gsync 120Hz TV but fixed them (I think) by switching GSync off for iRacing, setting the TV to 60Hz and turning VSync on in iRacing and locking to 59fps in RTSS. I don't see why we should have to stop using Afterburner (for underclocking and custom fan curve in my case) just to use iRacing smoothly. The stutters I see happen mostly on newer tracks like Circuito de Navarra, so I'm not sure if it's also down to optimisation perhaps on iRacing's end.

What about Geforce experience ? And Rivatuner statistics server ? The first I use for max fan control rather then auto fan when it’s hot weather and 2nd use for capping my FPS…

Hey mate,u seen to have a queat 3 and a 4080 also Any tips on setting ot up for iracing and how to run the headset Thanks Jamie

Can anyone explain what "Frame Re-projection" is exactly? Hardware is trying to recreate something it missed?

I have only GPU temp monitoring checked and polling is 2000ms also you can entirely pause monitoring if you right click on the graphs, on my MSI skin I can click DETACH and show graphs and you can pause it forever this way

Have you tried it with any other hardware monitoring programs? HWinfo64, AIDA64, OCCT...? Are the stutters a result of contention for the resources, or is the monitoring software too aggressive, or too inconsiderate in how it polls the hardware?

user error. you have 500 things being polled/tracked in afterburner, of course its going to cause lag/stutters

“MSI Afterburner is to blame,” but this issue also occurs with Precision X and HWINFO64. These problems have persisted since the release of the 3000 series and have never been resolved. Most of us who have encountered this issue simply shut down any monitoring tools before starting a VR gaming session. This problem has been around for so long that I’ve stopped looking for a solution and just accepted that it’s easier to close these apps and move on. Thank you for addressing this issue. Hopefully, it will gain some traction and eventually get fixed. Ideally, we shouldn’t have to choose between monitoring our hardware and having a smooth VR experience.

a bit misleading, I agree that 3rd party apps can introduce weirdness as for you in this case, but to blame is iRacing and its engine and nothing else

Well, read the manual, read the forum. If you add sensors for no reason and especially those who have a high polling time sure it is having an impact. It's not the software itself, but how you configure it. In the Monitoring Panel of MSI Afterburner you can right click and enable the profiler panel which will show you exactly which sensor takes how much time to poll. Especially external sensors like those by perfcounter.dll have a huge impact. Use only those which you do need, preferably the internal ones and untick every other sensor. FPS, Frametime, GPU temp, GPU load, CPU temp and CPU load are not heavy and won't give you a noticeable impact while gaming.

Learn how to use MSI AB's performance profiler panel. It is not Afterburner, it is PEBCAK user to blame. Experienced users know how to troubleshoot issues like that and MSI AB contains the most detailed diagnostic tools for that.

Some sensors (like power or voltage) can have quite high latencies. The GPU driver can stall (it's the driver that actually does the polling when Afterburner or HWinfo or whatever requests it.) You can enable the sensor overhead calculator in Afterburner to see which sensor group is problematic and disable those. Although as always, it doesn't make sense to keep playing with monitoring software running. Use them only initially to find the performance sweetspot for your system, and after that's done, keep them closed.

Can also confirm this issue. Happens/happend in DR 2.0 with a 3080 Ti and a Pico Neo Link. Must have something to do with Nvidia drivers. Had been using it for years without any issues. Tried many old drivers but unfortunatly without luck. Also disabled all monitoring. Had to uninstall Afterburner.
