Fixed FPS: diminished aircraft performance

[Motomouse]

Instant Action L39 Free Flight Caucasus: When I use 45 FPS fixed my plane is slower versus FPS sync deactivated (90 FPS) compared to the other plane of the formation in this mission.

(I use the same low settings with both 45PFS and 90FPS for this comparison to make shure I achieve the 90 FPS constantly. I could not believe this behaviour in the first place, but different test runs confirmed the result.)

Nose wheel steering in the Mig15 and the L39 is noticable and substantially easier at 90 FPS versus 45 FPS fixed.

The input handling and simulation physics seem to be realated to the FPS. It should be independant from the frame rate. 

 

Can anybody compare their own experience? Is this only in VR? Is this different for particular headsets?

After further testing I can not confirm my first assumptions.
