Since a few weeks, don’t why, I have a huge performance issue in MSFS in VR (Pimax 8kx, Nvidia 3090, Intel 9900K).
With same parameters as before, as soon as I move the headset, I suffer double vision, or stutters, or both, hard to explain.
When no head movements, there is no issue, so I guess this is not linked to a perf issue with the game parameters.
And more strangely, I just discovered that the issue diseapears totally as soon as I change the focus from MSFS to another application (using windows alt-tab, to SteamVR for example).
Everything is back to normal behavior, I can move the head without any issue.
And of course if I move back the focus to the game, same behavior shows-up again.
I have re-installed the NVidia drivers, and all the Pimax tools, without success.
