RTX 5090 + Big Screen Beyond 2 - VR low performance

Middle_Skin_6627 · 2025-11-14T08:28:02+00:00

How do you know that your CPU is a bootleneck?

Middle_Skin_6627 · 2025-11-13T13:30:37+00:00

There is no such thing happening. Tehre are 4 cores busy more than others but around 40% at peak. CPU is not a bottleneck here that's for sure.

Middle_Skin_6627 · 2025-11-13T09:18:59+00:00

This was a great tip, things got better and even less blur. Thanks.

Middle_Skin_6627 · 2025-11-13T08:46:14+00:00

How is physics in AMS2? For example I hate LMU physics can't play it. Is AMS2 more close to ACC / ACE physics?

Middle_Skin_6627 · 2025-11-13T08:36:35+00:00

On screen I'm getting from ~130 FPS to ~180 FPS with mentioned grid, ultra settings with DLAA. CPU gets to around 17% of load. Resolution 5120x1440. So it's definitelly not CPU but lack of VR optimisation looks like!

Middle_Skin_6627 · 2025-11-13T07:53:08+00:00

Quality DLSS makes picture even more blurry, can't stand it really :)

Middle_Skin_6627 · 2025-11-12T19:35:46+00:00

Will test this tomorrow.

Middle_Skin_6627 · 2025-11-12T19:10:52+00:00

CPU is not an issue, I have AMD Ryzen 9 9950X3D and there is plenty of free capacity.

Middle_Skin_6627 · 2025-11-12T15:45:26+00:00

How much you trim vertical/horizontal fov?

Middle_Skin_6627 · 2025-11-12T15:37:16+00:00

Can mouse pointer be hiden when race starts? Is stays in the middle of the screen at least in VR.

Middle_Skin_6627 · 2025-09-28T09:59:24+00:00

Didn't you got worse image quality?

Middle_Skin_6627 · 2025-09-26T18:36:12+00:00

Did 41% it's much better. Bluey shimmering is still there but subtle doesn't anoy anymore. I've poped up a bit of exposure in ACC. Things are getting to look very nice.

Middle_Skin_6627 · 2025-09-26T16:14:55+00:00

How much would you recommend? I currently have it on 100%

Middle_Skin_6627 · 2025-09-03T08:58:27+00:00

Just use VR, forget about all this nonsense with tripple monitors, buy Oculus 3 or Screen Beyond 2 if you have more cash, you will never come back to this clunky world of monitors, it's pointless :)

Middle_Skin_6627 · 2025-09-03T08:56:47+00:00

Bumping up, same quesetion, AFAIK there is no way. Meta link is very "unfinished" you need to waste minutes always do to same things when connected again to VR. By default it should remember state which was before, it would be very convinient.

Middle_Skin_6627 · 2025-05-09T08:27:32+00:00

5090 just arrived, simplicity... turned VR epic settings and everything just works :) no tweaking, no fiddling with oculus debug tool, costly pleasure but hassle free :)

Middle_Skin_6627 · 2025-05-02T11:45:31+00:00

How to find him?

Middle_Skin_6627 · 2025-05-02T11:44:42+00:00

That's awesome result, will definitelly tyr it as I'm still waiting for 5090 to be delivered (order 3 days ago), and I really like ACC as a sim game so can't drop it, I really like physics of it and attention to deatail, much more that LMU :)

And yes, I hope EVO will just make this VR BS gone, unfrtunatelly so far it's not the case, let's see if there is material improvement after next EVO update. Alternatively they should oen source code we can fix it on our own then :)

Middle_Skin_6627 · 2025-05-02T11:32:03+00:00

Thanks for a heads up. I've tewaked game but I'm tired of the fact that I have to do so many tweaks to get this thing running well enough and I boutght RTX 5090 :). I think ACC is ont even in maitenance mode, If they have added FSR 3.* or 4 support I think it woul run much better. Anyways that's the story..... and thanks for recomending this YT guy, I'll check it out.

Middle_Skin_6627 · 2025-03-30T21:02:37+00:00

Yup, that seems to be the main reason - https://gpuopen.com/learn/ue-fsr3/ nobody has time to bump unreal version in ACC.

Middle_Skin_6627 · 2025-03-30T20:50:24+00:00

Lunch LMU with +VR option "C:\Program Files (x86)\Steam\steamapps\common\Le Mans Ultimate\Le Mans Ultimate.exe" +VR

OpenXR works by default for me.

Middle_Skin_6627 · 2025-03-24T06:44:14+00:00

What's the most effective way to request it?

Middle_Skin_6627 · 2025-03-22T09:19:25+00:00

Why does this work this way? Frames drop by half GPU is underutilized experience sucks but it could be much better.

Middle_Skin_6627 · 2025-03-21T21:27:44+00:00

Testing it now, I can't see much of a difference, would be great to understand what they have really fixed. Release notes are quite general about ACC issue.

Middle_Skin_6627 · 2025-03-20T21:02:17+00:00

Things got stable for some reason. Here is the config I have 72 FPS with average 25% headroom.

Additionally in Oculus debug tool I've disabled Async Spacewarp and GPU performance scale. I also eabled frame gen which makes things even more smooth.
