Everytime I load killing floor 2, my screen is very blurry making it incapable to read let alone play the game. I have tried to change my resolution in the config and in the games properties yet it still is very blurry. As well, it seems that the steam overlay is around 80% of my screen when I tab out. I have been told that my resolution might be stuck at 320x240. Anyway, what can I do to fix these problems?? Thanks
