So like many people, I can't run the game in fullscreen mode. When I run the game in windowless mode, however, I can't get the performance to be smooth without reducing the resolution. If I make the resolution smaller, the game runs just fine. My problem is that reducing the resolution means the window for the game is smaller than my screen and therefore only fills a corner of it. Is there a way to make that window fill my entire screen without increasing the graphics processing resolution?
