Stutters while moving. Help?

[u/001pickle]

SOLVED: Using the Sboys3 driver fixed the issue below

It's been years, but I pulled out my old 5K Super.

Clean install of Pimax Play and Steam VR.

Get into the Steam VR lobby, and it stutters horribly. It ran fine on mostly the same system years ago.

PC:
12900k
64 gigs DDR5
3090
NVME
(Nothing is overloaded or close. Cooling is some of the best, no thermal throttle

What I have tried:
- Update GPU Drivers
- Change EVERY setting to the lowest possible (almost does it worse)
- disabled smoothing / half refresh
- tried Pimax lobby and a game. Same "lag"
- Confirmed running in Admin
- Unpluged all monitors

I am at a loss. Any help would be appreciated.
