AMD Athlon XP 2800+
1 GB RAM
1 Nvidia 7800 GS
And as i said, i really did everything you and the other helpful members posted or recommended. So thats not blaming the game, its a fact that the game any my computer dont work too well with each other. And that is a bit strange as even CoH or MedievalII run both without problems on medium to high settings. -> no rant, no blame.
