What are the system requirements??? o_o;
It's completely tanking my laptop. I'd say it'll run at maybe 5 fps, and the sound is very choppy. Pretty much impossible to do anything. It also takes up about 600MB of RAM.
I have a Core 2 Duo at 2.1 GHz, 4GB of RAM, and nVidia graphics. It's not a speed-king, but it can play Half-Life 2 without a hiccup, and emulate some Gamecube games.
