I have a TIbook 667, and was wondering what I can expect to play (enjoyably). I've tried UT2k3 and the game is unplayable, it's around 1 or 2 FPS with all options on minimum. The TIbook has 512 MB ram, and 16 MB vram. I've been playing EV nova, but the FPS on that is only around 45 at max! What's up??? I've also tried the MOH spearhead demo (I'm on cable) and it's playable but gets pretty choppy at times. If I got Simcity 4, would it be unplayable or would it play fairly smoothly at medium detail? I got the PB for $1000, would've buying one of the newer PBs for $2000 have been a better choice? Also, is there anything that I can do that will speed up some of my games?
