I've been playing BF2 single player at 1600x1200, medium settings and it's been clipping along at 60fps as reported by FRAPS. Sometimes around 74/80 FPS. Keep in mind this is on a T1300. Sometimes there's lag, but it clears up quickly. 2GB of memory would fix that problem, though. Not sure about Multiplayer performance. I don't play well with others.
Haven't Frapped my performance in CoD2, FEAR or others yet. Been busy.
