VR Performance Issues High CPU Usage & Stuttering (vr server background prosess)

[TonyBamanaboniNZ]

posting this here as steam support wont let me upload this as a ticket.
Since yesterday, I’ve been experiencing significant performance issues when playing VR games on my PC, most noticeably in VRChat when avatars are loading but im also having the same issue in games like beat saber. I’m encountering unusually low FPS and intermittent stuttering, where the display freezes for 0.5 to 1 second and briefly shows the SteamVR dashboard.
I suspect this issue is related to SteamVR, as I’ve checked Task Manager and noticed that the VR Server background process is consuming 60–70% CPU usage—often higher than the actual games. I’ve tested both the stable and beta versions of SteamVR, but the problem persists in both.

The only temporary workaround I’ve found is manually setting the VR Server process to run in efficiency mode via Task Manager, which improves performance back to what it was before i noticed the issue.

Could you provide any guidance on resolving this issue? Any help would be greatly appreciated. im more than happy to provide you with any other information you may require.

normally my game sits at 180+fps but recently its been 30 - 40

PC specs are
cpu: amd ryzen 7 5800x3d @ 3.4GHZ
ram: 4x8 sticks of Kingston hyper fury @ 3200MHz
gpu: nividia 4070 ti running game ready driver 572.42
storage: samsung nvme ssd 980 1tb

I've started to notice the same issue I'll try to put it in efficiency mode as well to fix this

Glad to hear I'm not the only one let me know how it goes on your end after you try the temporary fix also drop your specs too as it may help whoever at steam finds this bug to fix the issue
