I'm using a 1ghz 12inch iBook currently and I recently started playing the original Unreal Tournement again. Last time I played this game was on my 400mhz iMac, and frame rates were low 20s/high teens. With my iBook, with 24 more megs of VRAM and a G4 1ghz, the frame rates are only up to high 20s-high 30s. Not much of a jump considering the jump in hard ware I'm working with. Why is it not better? I played agains someone running on a 866mhz G4 with the same amount of VRAM and it just looked much better. Is it the laptop screen that just doens't look as good? Or is it something to do with the specific parts of a laptop that don't work as well? Back in the day (okay, 4 years ago) I remember a friend running UT on his PC with 500mhz pentium and 16megs of VRAM was getting much better frame rates.
