VR Performance Issue - CPU Bound Despite Powerful Processor

[Gideon312]

Hello Forum,

 

I'm encountering a perplexing issue with my VR setup, specifically in DCS (MT). Despite having a robust CPU, I find myself CPU bound even when running the game at its lowest settings in VR. When looking sideways, I only achieve around 20-30 FPS with some slight stutters. Interestingly, in non-VR mode, I can fly with maximum settings and am GPU bound, achieving a smooth 150+ FPS.

 

I'm using an Nvidia Control Panel with default settings. OpenXR tools for WMR are set at 150%, and motion reprojection is turned off. OpenXR toolkit disabled. DCS MT as administrator. CPU unpark. 

 

There is some setting I’m probably missing.  Any insights or suggestions to optimize my VR performance would be greatly appreciated!

 

My specs are:

• Gigabyte X670E AORUS MASTER motherboard
• AMD Ryzen 9 7950X3D processor
• 64GB DDR5 (6400) RAM
• Geforce RTX3080ti 

 

Thanks in advance.

set WMR back to 100% (it is already set to 150% of the physical, when you set it to 100%), ... so that wont help ...   I am also aware that some games run on the wrong CCD on the X3D processors so you might try using process lasso to make sure DCS is running on the correct 3D CCD ..

Just wanted to drop you a quick note to say thanks for the advice on setting my Windows Mixed Reality (WMR) to 100%. It genuinely made a difference in my FPS—awesome tip! 25-30FPS to 55-60FPS (with some stuttering looking aside)

Now, I’m looking to fine-tune things even more and explore Process Lasso. Any specific tips or best practices you’d recommend for getting the most out of it?

Appreciate your help!

Not really familiar with the AMD side of the house.

As I understand it, the your processor has two groups of cpu's  one with the 3d cache, one with out, the 3d cache is the one you want for games, I'm not really sure which ones that is, sorry.

Glad the wmr settings helped!
