I am getting an incredible number of dropped frames as shown in fpsVR. I can easily be on over 100 dropped frames in a minute or so.
This is even when running at a very low SS of 30% for example, and framerate stays at 90fps, GPU and CPU usage very low (3090 & 10900k). So to be clear, this isn't low framerate or reprojection etc, it is literally only "dropped frames".
Other sims run great, just something is causing an issue with DR2. I didn't have this problem with my Vive Pro.
