Blanko has a shit rig. I haven't come up with an appropriate term for mine. I get 15-20 FPS at places where snow is falling, and sometimes way worse depending on how much stuff is going on on the screen. Indoors I generally get around 45, depending on what's going on of course. It was a lot better at the start of the game though.
I thought my computer was shit, but apparently it's way worse than that, seeing as how I run it in 1152x864 with the graphics settings otherwise set almost to max, and I get way worse performance than Blanko.
For all I know, this is worse performance than what you get on a console, but I take shitty performance over using a gamepad in a FPS game any day.
