Recently i changed from fullscreen to borderless with no problems, now i tried to change from borderless to fullscreen and no matter what i do it just won't work, it is always borderless even if saying it is fullscreen in the settings, now i get frame drops like hell.
1- Changing "LastConfirmedFullscreenMode=0", "PreferredFullscreenMode=0" to 1 in GameUserSettings.ini;
2- Set "-fullscreen" in Steam launch options;
3- Running the game as administrator and rechanging to fullscreen in game settings;
Yesterday when i did option 1 it seems to have worked but today it just won't. The game performance for me is 95% of the time great but now the frame drops makes it pretty bad as i'm getting 40fps when smokes are dropped or too much explosions are happening.
What can i do?
