[Skyrim VR]: CPU performance problems

[FedX]

Hi,

i have serious CPU Frametime problems in some very specific scenes and i cannot figure out where it comes from. Even if i disable all effects and use no other mods, the problem keeps the same.
I tried every setup, even another CPU (5800X) but nothing helps. If i deinstall ENBSeries complete the problem is gone.

In this Scene the CPU frametime is horrible:


if i turn the head only a few cm to the right everthing is fine:


So i would assume its because of this single tree(?) But in other scenes where i stand directly before trees everything ist good.

If i change the ini to the following:
[GLOBAL]
UseEffect=false

[EFFECT]
UseOriginalObjectsProcessing=false
EnablePostPassShader=false
EnableAdaptation=false
EnableBloom=true
EnableLens=false
EnableAmbientOcclusion=false
EnableProceduralSun=false
EnableCloudShadows=false
EnableSubSurfaceScattering=false
EnableSkylighting=false
EnableSunRays=false

The problem stays the same.. are there additional effects which are always active ? I dont understand why this problem occurs even if i disable everthing.

System Specs:
-ENBSeries v0457 (also tried 0375)
- Valve Index 90Hz@100% SS
- 32Gb DDR4
- Ryzen 5600X
- Radeon 6800XT

best regards

That site banned in russia so i can't see. But in general, at least for non vr skyrim (so most likely for vr too), AMD videocards having problem with power management when they reduce gpu or vram frequency with mod installed. How to fix that i don't know. Mod do have certain performance impact even is UseEffect=false, but not very big.

Thanks for the answer.
But in my case it seems more of a CPU problem regarding to fpsVR..
I'm trying to get an rtx3080 since months now but it's nearly impossible..

Ok i found the mod VR FPS Stabilizer and EngineFixVR i and that makes the CPU spikes a lot better..

[ENBSeries]

Run some tool which display frequencies of videocard to make sure it's not what i said about amd cards power management bug. Also for me in vr games greatly helps to change priority of steam services to normal in the task manager. Don't remember which of them, several processes have higher priorities, maybe steamvrserver or soemthing like that.
