Has anyone tried Portal on a 330m MBP yet?
I have a late '09 2.26/9400m MBP and Portal seems almost religiously capped at 30fps, and seems to just between 30fps and 60fps when you're not moving. Very strange behaviour indeed. (All low settings @ 1024x768 iirc)
I completed Portal on the Mac the other day, and whilst it was fairly cool to be playing on the mac (anyone noticed how alt-tabbing out actually works, something that has never worked properly from the days of HL1 on windows!) the horrible mouse acceleration curves made it very difficult - I couldn't imagine playing an actual FPS like CS:S or HL2 on it.
