i have an IBM T43, 2.0ghz, 512mb RAM, 64mb graphics, and the game runs. albeit slow as a dog, but it works, no graphical anomalies at all.
on my p4 3.2ghz, 1gb ram, 128mb 6600GT, i get stripes all over the screen, and randomly the games slows to a crawl.
on my x2 4400+ with 2gb ram, 256mb 7800GTX, win x64, stupid game just crashed all the time - not even to desktop, just total freeze.
so in all, i'm basically almost only able to play on my laptop. stupidly.
