Arma uses wrong monitor frequency
New, NormalPublic

Description

SInce the last update, Arma reverts to the 30Hz frequency of my monitor instead of the 75Hz frequency of my monitor. It seems to happen everytime I ALT/TAB to my desktop and back. My desktop is still running at 75Hz. I have to use AUTODETECT from the video options menu to recover to the right 75Hz frequency, and then I have to re-set all my settings.

Steps To Reproduce

Start Arma (via Launcher). ALT-TAB to desktop and ALT-TAB again to switch to Arma. Arma then uses the 30Hz frequency instead of the 75Hz frequency. If you use AUTODETECT from the video options menu then Arma switches back to 75Hz.

Please note that the game is running fullscreen. If I set the game to fullscreen window, then the game obviously stays at 75Hz.

Additional Information

This seems to be related to the fact dat Freesync is not working anymore. I will enter another bug report for that.
