I used View speed vertical windoes to game 6 month. %0mm windows to game 1 year. %110mdh windows to game 2 moths. Now I'm sure. If you match your sensitivity from windows to game it affects your aim. %0 feels slow in desktop fast in games it causes inaccuracy for me. For check this theory I decided to change my windows to game method MDH%100 basically I dont change my 3d game settings they stay same I just changed my WPS. I suggest everyone who using %0mm windows to game and feels inaccurate in 3d game try mdh%100 for only hipfire.
