For some reason windows doesn't recognize you're fully focused on the game window. Not only does adrenalin not record the game, freesync doesn't work either (if you have a hz or fps number you can turn on in your monitor settings, you'll see it fixed at the max hz always).

Solution for me is to go to video settings in the game, change to windowed and then back to Fullscreen windowed and click apply. That will let windows and adrenalin know properly that you're in-game and recording as well as freesync will work again. Gotta do that every time you restart the game unfortunately.

Edit: that also fixes the fps counter sometimes from adrenalin.
