Freesync seemed to be working fine with 15.4 beta driver, and all games worked fine. Then I updated to 15.4.1 beta and that's when I noticed tearing in Mortal Kombat X. I thought it was some sort of bug in the game, but then I noticed that the monitor was stuck at 2560x1440 100Hz, instead of 144Hz (I'm using DisplayPort cable). I tried few Catalyst drivers such as 15.3, 15.4, 15.5, and still unable to select 2560x1440 144Hz. When I select 144Hz, the resolution jumps to 1920x1080.
Anyone else experiencing similar issue? Latest driver cleaner didn't help.
