Greetings,
recently i saw Wrack get one big price discount in my wish list so i decide to give it a try, after successfully downloading the game ( game size is about 800 mb ), i lunched it, everything become PIXELD like 320x160
which looks like the game is only suitable in gamepad or sth like that, i know it is a doom like but it doesnt mean i have to play this game under DOOM resolution! I have no idea what's happening and i cant figure out how to change the resolution ratio in the game setting, so help me plz!

P.S:
I use win8.1 as my system, maybe the configuration identifies it as one pad ?
