I have an Athlon 2800+, GeForce 6600GT, 1 gig 3200DDR Corsair, and an 80gig Maxtor ATA133 HD. The game is running just fine in 1152x864 with 2x AA enable. However, whenver I'm walking around the first base (just bought the game) whenever I walk into a new room in the base the game halts for about 0.5 to 1 second to "load" the room, then it runs fine again. Is this a memory issue? Any idea how I can fix this? Thanks!
