Low performance in VR

[rasteek]

So for the last few days i have been playin around tryin to dial settings for VR and its pretty much not possible. 

I tried default airports, EGLL with everything disabled, all settings on low and i get maybe 25 FPS in VR ... tried Cabin, No cabin, different airports and so on.
My specs are 7950x3D, 5090 rog astral, 64GB Ram, so basically top performing PC.

Did any devs tried it in VR and if they did how are their results?

Thanks

Hi!

i9 13900, 4090, 32 DDR5, Varjo Aero here.

I get stable 30fps in FS2024, on DLSS4 preset K, graphic setteings custom between medium/high. You have powerfull rig, what VR hardware do you use?

Hi,

I can get 120FPS no problem in cessna at random airport, problem is a350 on any of the heavier sceneries. Or a330 or fenix a320 for that matter ... 
And i can get 140FPS all ULTRA in any of the airports in airliners in 2D mode

Interesting is that when i look around cockpit or turn around and just watch cockpit doors fps goes under 20 or hovers around 25 ..... or if i just look at MCDU, FPS goes down.

Switching between DLSS or TAA does not make any difference at all, even if i lower all settings to LOW i only get 3-8FPS more .... 
I tried with Oculus Debug Tool, SteamVR, Virtual Desktop and it all performs around same numbers, no matter what i do ....

Its like LODs are loading even if i dont look at them but im not debug expert in developer mode so i cant be sure

I have Quest3 and im on Win11 24H2, with latest nvidia drivers and on SU2 beta

Hello,

Can you send me a screenshot of your in-sim settings? It may also help to completely uninstall then reinstall the aircraft. Some have done so and fixed performance issues.

Thank you 🙂

Like i said, i tried with all low settings, everything to a minimum. and it was few FPS more. Dont have a screenshot. But will make it after reinstall if it will be still the same.

Will try to reinstall, do i just do it in IniManager or do i need to do anything else?

 

thanks

I have also a quest3, a 7900x and a 4080. 30 FPS are always possible, 36 is somtimes hard in VR on complex airports. Im using high settings with DLSS4.

It is crucial to keep the VRAM usage under the limit. Nothing else kills the FPS like full VRAM. Therefore I'm using the low-res textures.

yeah i have plenty of VRAM, so that is not an issue, if i get 36 stable in a350 at EGLL im a happy man honestly 😉

I would say that the issue has to be on your side, not A350. With a rig as yours you should have no problems at all to get 30fps in all scenarios and settings medium/high. Difficult to say if it is something with airframe installation or other software/hardware issue.

well funny thing happend, i tried EGLL in cessna 404, and had same FPS issues .... then i tried A350 in EGCC and had 72 fps (36per eye) ... then i tried EDDF in a350 and dropped frames again, so im now VERY confused what is going on 😄

Ok my last reply got me thinkin... So i went and rechecked all my scenery, lo and behold, MSFS decided to re enable all default scenery, so it was all duplicated.... Why did it do that, NO IDEA. 

Anyway, i disabled all my duplicated scenery (wish there was a good tool to check all that, OR BETTER YET WISH ASOBO WOULD GET THEIR S*** TOGETHER) and i got 68 FPS on all ULTRA in EGLL in A350 🙂 in VR (will fine tune it later 🙂 ), and 180 in 2D 🙂

i would notice it before, but my VRAM was chillin at 18GB with both sceneries so that is why i never checked it.

 

well anyways, thanks for all the replies 🙂  this topic can be closed now 🙂
