Fullscreen mode stuttering

Hi all,

I’m having major issues with alt+enter to get the game to fullscreen mode, without getting major fps lag. I know it has something to do with my screen (a Dell S3220DGF, 1440p/165hz) and the game engine. But everytime I alt+enter to go to fullscreen the fps drop from 60 to 30-45 and the game plays like crap. Only by fiddeling with alt+tab or alt+enter I can get the game to run normal, without any real thought behind the solution.

Any clues on why this is happening and what I can do about it? It makes playing the game a real pain with having to deal with this every time.

Love the game though!!
