I'm having the weird issue that in game I never get 144hz my max is 90+/-. Ingame menu is no problem at all but when in a match I immediatly get a drop. Dx12 is not on all the specs are on auto, except for the frame rate which is set voor 144. When I bought the screen some time ago I was able to reach it and in other games it is no issue but ever since an update I never get the same result.
Run i7 6700 + 1080GTI + 16GB DDR4
