I have the exact same problem on vive.
I checked in afterburner: every 90s my GPU usage drops severly, and each time it has a matching “freeze”, what is weird is how regular it: Image
So far I: - Reinstalled SteamVR - Removed my CPU/GPU overclocks - Updated GPU Drivers - Switched the game from a 5400rpm HDD to a 7200 - Reset all my Supersampling options - Tought it was the cells loading so I set the uLargeRefLODGridSize back to 5 (was at 9 for some reason)
Nothing had an effect.
CPU/GPU temperatures are more than acceptable, no thermal throttling. I don’t really know what to try next, other than trying to disable mods one by one and see if it has an effect :
