I just got a new ViewSonic XG2401 monitor which supports FreeSync and has a 144Hz refresh rate.
I was able to flawlessly enable AMD FreeSync in my Crimson settings after enabling it in my screen's OSD.
Afterwards I set the monitor refresh rate to 144Hz in windows.
In CS:GO I capped the frames using fps_max to 144 since the FreeSync range on this display is 48Hz-144Hz.
The game becomes unplayable, I have constant stuttering and some flickering even though the FPS stay between 142-144.
It feels like I'm lagging but my ping stays around 28ms.
CS:GO isn't the only game I have issues with. In Overwatch I get increased screen tearing ironically.
Once I disable AMD FreeSync in the Crimson settings everything runs smoothly.
