ive got everything on medium settings at 800x600

my pc is

AMD2600+
512ram
nForce2 MOBO
Geforce4 MX440 128mb

I've got xp home, with dx9.c and sometimes the game runs well, other times it doesn't. I'm pretty learned when it comes to system performance so my pc is running optimal. My card is fairly crap, but still should run well judging from what other people have been saying (gforce2 runs it so well!)

Maybe its a directX problem, or just the demo is running some weirdo video rendering etc etc.

Hopefully it's the demo...
