I’ve made a habit of flying a default route in VR after each update since the transition from SU05 to 06. Identical settings, same airport, same time, weather only clear skies, multiplayer off.
With the last SU, the frame rate dropped from the previous average of 45 FPS to 30 FPS, with short-term dips of up to 16 FPS.
Since Maverick i become around 33.
Luckily I’m not the only one affected. As a result, the error is guaranteed not to be on my system side.
