Problem VSync (sometimes) not working in full screen mode

[Nikogori]

I am having a problem with VSync in full screen mode. This happens on both d3d7 and d3d9.
This doesn't happen in windowed mode.
(Disable vertical sync is not enabled)

This is normal.



Open dialog (e.g. Ctrl + F1) and click on it, VSync stopped working.



Hit Alt + Tab or Windows key. Frame rate has returned to normal 60fps.

Have you tried forcing VSync on via your GPU control panel? I haven't managed to replicate this problem at all on my end.

I found the culprit. I have disabled AMD FreeSync and orbiter keeps steady 60fps.
