Description of the Issue
I fly in VR and very tightly optimize performance in order to keep a smooth experience. Recently I was trying to track down an unusual and consistent cause of reprojection occurring, seemingly about once a second during flight. This wasn’t a problem I was having recently so I wasn’t sure what was going on.
I won’t bore you with the troubleshooting steps, but eventually I realized that the frame spikes only occurred when the aircraft was in motion. As soon as I stopped, they went away. If I started rolling again, even very very slowly, they came back. Like a heartbeat pulsing every second or so. I thought for sure it had to be something monitoring SimLink so I started closing things that did, with no change. Then I recalled that I had recently started running the SimLink app again, and sure enough as soon as I exited that app, all hitches went away.
I have a video showing exactly this with a frame time debug on, but it is too large to upload.
