for what its worth, i installed FEAR last night and let the game auto-detect settings. it went with max for virtually everything. i was gonna up the resolution to native, but i got a warning saying that the game wasnt optimized for this res (it seems to only be optimized for the "standard" resolutions). so, its currently running at 1024x768 or something similar to that.
the game runs super smooth. averaging around 40-50 fps. fans dont even stay on all the time. doesnt get too hot or anything.
so to those people posting in the thread above me and saying that its ridiculous to try and run a game like FEAR or farcry (which is 2+ years old!) - maybe you ought to try it first.
FEAR ran fine on my previous MBP 2.0Ghz CD 2gb ram, 256mb vram. I can only assume that it will run much better on my new C2D 2.33Ghz.
Call of Duty 2 runs perfect on C2D with most of the settings maxed, where I would have to go with medium on CD.
