Desktop frame rate and vsync effects on FPS

I’ve done some more testing using the latest NV496.84 driver which itself did not lead to any significant performance differences vs. 496.49 for me. However, what I did was to compare the following window focus situations:

  1. MSFS is the only window visible on-screen and in-focus (mouse-clicked)
  2. MSFS plus Start Menu raised via Windows key
  3. All windows incl. MSFS minimized so that only the Windows Desktop is visible.

I’ve repeated the tests 3 times each but variations were small and results reproducible so I included only one plot each. The results show that with my setup I’m gaining even a few more minimum FPS (and +1FPS average FWIW) by reducing 2D visible output to Desktop only.

What’s more, when checking Windows Task Manager, ANY additional windows visible on-screen (WMR App, Flight Recorder, …) will lead to a small additional GPU load of 1…3% with my RTX3090. Maybe this is more significant for users with lesser GPUs so hopefully this info will be helpful for others.

Now let’s hope SU7 won’t bring us any performance regressions…
