Hi,
I play CoD4 on a 2009 13" Macbook Pro. My specs are a Geforce GT 9400m (256), a 2.26 C2D, 4 Gigs of 1333mhz RAM.
I play CoD4 at 1152x 720 or something like that. Textures are all high, and the rest of the stuff is off, like shadows. I usually get around 30ish FPS on Multiplayer.
My issue is that, after about three-and-a-half minutes of gameplay in ANY game with ANY connection speed, even if it's been smooth before, I get lag/hiccups that will have short periods of slowdown, then fast, then short periods of slowdown (1.5s), then fast again. This ends after around two minutes. Is this performance issue due to the GPU? Anyone else get this?
 
It might be heat. Any idea what your temps are?

TBH, I've pretty much stopped playing CoD4 on my MBP since building a gaming PC. OTOH, you are lucky to get 30 frames from that 9400m. :eek:

I really don't know. I don't have any temp monitoring software, however the computer is silent and no fans ever spin up until I've been doin it for at least half-an-hour.
 
It's a temperature issue, I had the same thing happen. Download SMCfancontrol and turn up the fans when you play.

If your MBP isnt hot dont bother with that crap.

Normally I would agree and I don't usually like the idea of tweaking hardware or even simple things like fan revving, but it seems to have worked, whatever it is... ...Only lag I experience now is because of my terrible internet connection.

Than the heatsink is not making good contact with the CPU if the metal above the keyboard wasnt hot.
