Question VAM not using GPU OR CPU effectively

[curunir]

Hello everyone. I'm on 1.22.0.12. I just upgraded from an i5-10400F / 3060 ti to a Ryzen 5 7500F + 7900 XTX. However, my FPS in VR are barely improved.

At first I thought it was due to AMD Chill (I normally have it limit the framerates to between 45-64 fps). I disabled that but it didn't make any difference.
Then I thought it was due to the asynchronous spacewarp option in VR desktop (limiting to fps to 45 so it can interpolate to 90 fps). I disabled it too, but that didn't make a difference either.

I can be on a scene of moderate intensity and get 40-45 fps, but with the GPU usage hovering around just 60% (this checks out with the board power draw, which is only around 200 watts). Before you say I'm being CPU limited: at the same time my CPU usage is hovering around 20% on just a single core.

So my question is: if VAM is not being either GPU or CPU limited and I don't have any artificial frame limits or frame generation/interpolation, wth is limiting my performance?

I was expecting to hit around 90 fps at least with this setup (of course depending on the scene and quality settings) and the headroom is clearly there. But for some reason VAM just refuses to use more resources which are actually available. (~40% available headroom for GPU, ~80% for CPU)

It is basically single core cpu limited. Thats why not even high end setups will achieve very high fps in VR at least

I understand, but as I wrote it's using only 20% of that single core in my case

I'm on an i9-13900K w/ RTX 4090, both AIO water-cooled, sadly limited to 32GB because of a damned Asus MB issue (last time you bastards..). And I still have to keep it simple to have a decent FPS.

Basically: Learn to appreciate women with short hair, in small rooms, and turn off extra lights.

alot of it has to do with the physics. within the "performance monitor" pay attention to the "physics" because you want to try and keep that low. For really intensive scenes i would change my "Physics update cap" from 3 to 1 and that normally increases the FPS by a large amount and my GPU utilization and CPU utilization shoots up as well. and I can see my GPU maximum power and CPU packpage power hit it's limits. But if the physics of the actual scene is too high; my GPU and CPU utilization drops, and i have alot of headroom and the FPS is relaly bad.

I hope this helps... because it is not your system normally. But it is the scene or how you have your preferences configured to handle the scene.

I am in a similiar situation to you guys where i have upgraded parts or even reformatted the entire PC and noticed huge differences in performance even with the same hardware from different installs... and there are just some settings I have overlooked and i was not able to achieve the same performance until adjusting some of the settings like physics caps ect ect.

ALSO, try this out! It helped improve my performance a large amount and it is worth a try: https://hub.virtamate.com/resources...to-30-faster-physics-up-to-60-more-fps.43427/

Just going thru this guide helped me resolved some of my performance issues from session plugins that i was not aware of that was causing issues.

I am with you on that.... I have the same CPU on the ASUS Hero and i felt like I have been beta testing both the CPU and MB since the CPU's launch... it is the last time I build a PC at launch because I absolutely love this CPU and MB but it would have nice to not deal with the bios issues for the first few years.
