Choppy, Stuttering, Jittery Performance (used to work fine)

Any head movement renders choppy and makes the game unplayable. Only on this game, no others.

According to steam VR performance metrics i'm all green and not dropping any frames. According to virtual desktop, same, consistent locked at 90fps, no dips, low latency. No obvious hardware bottleneck, even setting render scale to 20% yields no change in performance. Used to work fine on my OG vive.
