Okay I have tried 1000 times now changing my display settings from 16/10 to 16/9 unchecked the windowed mode box set my display to 1920x1080 and the game just wont launch into full screen mode. I built my PC from scratch I am not dumb just cannot get game to launch full screen have tried every setting I see available and still same thing everytime! I have tried checking the borderless check box tried having both borderless and windowed checked and unchecked change the resolution to everything my display will support but everytime it launches back to same windowed box and wont change help please???
