This is a definitive video if you want to understand how the differences in the processors and explaining how the different bottlenecks happen

Thank you so much. Great video! May I ask where you sourced the casters used on your monitor stand?

If the simulation logic doesn't run during a replay then this isn't a realistic benchmark

i noticed going from oculus VR to open XR (which was necessary in order to even use fpsvr app) resulted in higher render value and also more gpu usage i tried openxr toolkit and it has no foveated rendering, maybe thats why? how did you connect with your quest 3 and use fpsxr app to record the data? questlink with cable? does steam vr need to be running? also, my iracing is separate from steam. is that a problem? thanks

Hello de FRANCE, jeune homme est-il possible d'avoir votre réglage en fichier de votre content manager ? Je vous en serais reconnaissant. Merci et super job. Je joue principalement sur assetto corsa en 11520 x 1600 soit 18 432 000 pixel avec une 4080 Aorus Master un 5950x et 64 Go de ram.

Dude you’re doing the lords work! 😅 us sim racers appreciate you!

Appreciate all the work you put in. I think it’s important to highlight that in 1080p you’re extremely cpu limited for the 7900xtx which not necessarily indicates gpu performance and can therefore be a bit misleading. Good video tho!

Great charts. Very useful. I have a 5800X/3090, and I do VR. I'm trying to guess what it would take to run 120hz in a newer VR headset. I see that I shouldn't be too far off as is with my current set up, so long as I am ok with the occasional hiccup.

Dear CZcams algorithm, please promote this channel more. Thank you.✌️

Keeping a eye on this since I only have my PC case at the moment. Haven't decided what GPU to get and this will be one of my top simgames to buy.

do you think a 7900xt and a ryzen 5 7500f is enough for 1440p triples? gonna play on relatively low settings for fps

Your CPU will determine the experience you have in this Title. Remember...... This is a Brand New 2024 Game. Don't expect to have top tier performance with hardware from generations back. This isn't Iracing, AMS, ACC.. ect! Which are all titles that. Are 5-10 yrs old now. Upgrade your PC Especially your CPU to have the best experience in this Title!

I do not think anything in this video is remotely more than random guessing based on almost nothing. Also i have no idea what you are trying to say start of video? (Maybe it´s me not understanding some kind of internal jargon or something) You asumptions, convoluted calculations ect. you are manipulating (you own words!) distorting and to be frank; Nothing makes any sense, nobody will gain anything from you effort i´m sorry to say. I think you have good intentions and not sugesting trying to fool anybody, for whatever reason.

brilliant advice. these apps do some work in background, I agree. Will test to turn it off .7900xtx and ryzen 7 7800x3D CPU. VR is Pimax Crystal Light.

I love these vids man keep it up me and my friend have triple monitor setups he has 7800x3d with 4080s with 4k I got 7800x3d with 7900xtx with 2k we get similar fps, but its good to see a breakdown like this I love it

VR please. Thanks for video, I know you done some VR + GPU benchmarking earlier. There is no official VR support for Le Mans Ultimate, but when it comes, do we have a chance to get VR video? `yes really good sim. also Assetto Corsa Evo will be released soon.

thanks bro

So basically i need to get rid of my 6800xt and buy a 4080?? 😦

Good to know my 7900XTX would be enough with medium/high setting in triple 4k. Asked a refund because the menu was so laggy but still curious about the game.

Thanks for doing this Matt! One weird thing with both rF2 and LMU s that when Post Effects (or maybe Special Effects) on anything above medium your performance can really suffer. For this reason I have them both set to medium. I don't know why, it's just a really resource intensive setting. Like cubemaps on iRacing. With shadows on medium, detail settings on ultra and reflections on low I'm locked at 120fps on my 3440x1440 using a 6700XT and 5600.

How about the performance in VR?

You have genuinely no idea how happy I am to see this. I plan on simracing in LMU and perhaps iRacing in the future once I’ve upgraded my monitor from 1080p to 1440p

Thanks for putting in the benchmarking work. As a 7900xtx user i am very curious why the frame rate tends to be lower in cpu limited scenarios. Especially since VRAM cant be of any concern when it is about 1080p performance. I love the card and its working well, but i am driving iRacing and EA WRC in a mostly CPU limited way and wonder if there is more to get from it 🤔

No way you test LMU! rF2 and LMU are different beast when it comes to performance as we can see. I have 7600x with Rx6950XT and I must say that your prediction are spot on;) Is there a chance that you have thought about testing the CPU? I'm currently playing only VR and basically only LMU and rF2. I want to upgrade but I'm not sure if I should go for 7800x3d of 7900XTX/4080s first.

love my 7900 xtx. love lmu

I mean nvidia with an amd cpu is def the clear choice for sim racing. Even the community is on the same page. Its crazy if you being up amd in the sim racing community. Nvidia may not even realize but its like 95% nvidia so yeah. But I do believe overall it does perform better in sim racing titles. Yet amd cpus perform better lol. Also the fact its so close anyways in raster with nvidia not choosing it doesnt make sense when you get all the features instead of just fsr. So even in amd won or edged it out. Nvidia imo would still make sense for the extras they offer and upcoming sim titles that will be utilizing thise things.

Thanks. But fow-liage

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.
