Found that a lot people are wondering the performance of MacBook's 9400M. Especially about games under BootCamp. So I just post some of my experiences.
Below is a chart for some popular games’ performance. And because many games has no frame-rate benchmarking, so I’m just gonna describe what I saw. No AF or AA whatsoever. My MacBook is a 2.0G/2G version.
Crysis 1280×1024 Low
Barely playble. 10-20 fps I guess, but I did finish the game. So I think it’s playable.
Red Alert 3 1280×800 Medium
Smooth. The framerate will drop to around 10 occasionally, but 95% of the time, it’s very smooth.
Quake 4 1280×800 Medium
Smooth as silk. Only dropped to lower than 30fps in intense fights.
Doom 3 1280×1024 High
Smooth. Considering it’s a rather old game, this is no surprise.
Call of Duty 4 (Mac) 1024×768 Low
Barely playable. COD4 Mac is definitely slower than the WW under Windows. Which is interesting, as they use the same engine.
Call of Duty: World at Wars 800×600 Low
Playable. Maybe not as good as I expected, but playable. I managed to finished the game. And low is not that ugly too.
The Elder Scrolls: Oblivion 1024×768 Medium
Smooth.
Fallout 3 1280×800 Medium
Smooth playable. Very smooth, looks great too.
3DMark 06 12800×800 over 2100
World in Conflict 1280×800 Medium
Playable. In-game enchmark is around 14fps.
