Granted, I should have waited to actually play the game before voting for "low", however my system is rather slow....
AMD Athlon 64 X2 3800+ (939 socket)
2GB PC3200 DDR (yes, not 2, or 3)
NVIDIA 8800 GS
Windows XP SP3
I'll likely end up backing down the resolution, and everything else, down really far.... Hopefully I'll be able to play at all.
