Intel core i5-4670k clocked at 3.5 ghz (quad core) , 12 gb of Ram Not exactly sure what its clocked at, and a gtx 760 4gb super overclocked.
Normally I run at around 30 fps as well, however there are ALOT of things you can do to your game to optimize it for asylum.
I currently after optimizing play on around 60-80 frames, 35-45 in heavy combat - talking like 10 smokes, CQB, Staring Dudes in the eyes combat.. The only time i stutter is in vehicles because you cant avoid the rendering speeds sometimes.
