It appears Asynchronous Reprojection and Motion Smoothing are unavailable when using NVIDIA GPUs though no explanation is provided (tested using Valve Index Headset and GeForce RTX 2060). Are these features currently in development or is this a driver/hardware limitation?

As of the last update I've heard from anyone affiliated with Valve, Async Reprojection is currently blocked on Nvidia's end. This was within 2 months, not sure I have the exact quote on hand though. I'm also fairly sure Motion Smoothing is dependent on Async Reprojection working (but also Motion Smoothing doesn't work on AMD either and is completely unimplemented in Linux).

As of motion smoothing is supposedly working on AMD on Windows 10.

On Linux motion smoothing indeed does not exist yet.
