Does Macbook Pro Run CS:Source

Of course it will run. But not in highest performance. I would say the graphics are decent enough to play with no lag using bootcamp. Don't use crossover, bootcamp is a way to go for gaming on a Mac.

 

It can run at full resolution, textures on high, but don't enable AA nor AS.

 

Don't listen to people in this thread.
Also, what are you doing asking if a computer with probably the best integrated graphics can run a 5 year old game?!
CS:S runs on my Pentium 4 HT 3.4GHz with 1.5GB of RAM and an NVidia 6610XL, an OEM underclocked 6600.
I can run it full res: 1600x1200 no lag. with all settings on fullest they can be, everything enabled.
That's a 4ish year old PC.

 

Err... I know that.
I'm pointing out that I have a 6610XL. It gets something ridiculously low compared to the 9400M, when using benchmarking tools.
However, CPU and RAM do matter as well.

 

I run it in Crossover on a 22 inch external display without issue using both the 9400m in my MBP and the 9600GT. The 9600 is faster but not much. CS is an old game....so old I first played it over a modem...as in dialup. Source is a little more demanding but not much.

 

It runs very well on my base 13", so you should be good to go.

Even MW2 runs fine on the 9400m

 

well I know this won't help but my machine runs it at native 1440x900 with AA and AF enabled with HDR enabled. avg 70-90 frames.
