Hope this helps someone else as it was frustrating trying to disvover the cause but huge relief to find simple quick fix. I'm experiencing random frame drops/stuttering and reprojection even though there is a ton of GPU and CPU headroom. For VR, you need fix FPS matching the refresh rate (90hz for example). I use FPSvr to monitor my GPU and CPU, but no matter how low stress it on them, I still get about 80% reprojection. When the game engine renders the view for en eye, it outputs a "normal" projection of the scene. Motion smoothing Hello! I was click around in steamVR settings, and woundring about all the settings.

Either that's a placebo or you haven't restarted the WMR portal after making the change to the default. Features: - Set supersampling values. Basically it's a more aggressive version of motion smoothing. Change to: "Allow Asynchronos Reprojection: on" and "Allow Interleaved Reprojection: off". With default settings this means your FPS is halved and every other frame is a reprojection. My reprojection ratio was at 34% and doing so dropped by 30%. when i run steamvr, without even entering a game, i often hit 100% cpu core 0 usage, and start reprojecting like crazy. And yes, I am trying to do this without sacrificing refresh rate (90Hz), quality (to a degree) and my wallet.
