for some reason when i try playing crysis 2 in dx11 the game only opens in a really narrow and wide window mode, when i go to the resolution option it just says "undefined" and wont let me change it at all, any way i can fix this? does crytek just need to patch it for windows 8.

i really hope someone has a fix. specs below

i5 2500k
2x gtx 670
8gb ram
2560x1440 monitor

thx
