No. I'm on a 2.17 GHz Core 2 Duo MacBook Pro right now. I ran in a couple LOTA races while in hotels last year. LFS plays with very high framerates even on a 1920x1080 external display. Vsync on 60Hz and FPS never goes below that unless there's a ton of cars closeby in external view, like in a race start. The video chip won't antialias at or above 1600x1200 though. BTW, is yours a MacBook or MacBook Pro? I'm interested in knowing if LFS would be playable with the MacBook's integrated graphics.
