Do you have the same issue if you follow the OP’s steps to reproduce it?
Yes, I can also see the problem with the rhythmic peaks.
Exactly as described by Karvala21
Provide extra information to complete the original description of the issue:
although I noticed it in VR. I’m mostly in VR.
When loading the plane (it doesn’t matter which one you load) and placing it at an airport, everything runs smoothly,
Also in the VR environment. Image 1
However, when I go out of the VR into the normal desktop environment, it starts twitching continuously after 10-30 seconds. Rhythmic peaks can then also be clearly seen in the main thread, Image 2.
If I then switch back to VR, the peaks become even stronger.
But as Karvala21 has already described, the problem can also be reproduced after going back to the main menu and then loading a new flight.
I’ve just tried it and have the same problems with the problem.
