Yeah, I knew it was the processor. Great game. But, there is a lot going on, and with 1.5GB's of RAM, and two sticks of it being crappy 533MHz 256MB sticks, that, and running a Single-Core AMD Sempron 3400+ @ 1.8GHz OC'd ~ 2.2GHz, is just not going to cut it. The game doesn't rely too heavily on your GPU, like LOTRO, I can tell you thats for sure. As I have a BFG GeForce 9600GT OC-Edition, and I can run Crysis just fine. HL2:Ep2 and Portal both at the highest of the high. I'm with fredwv on the Dual Core.
