Hello there!

I got a 2008 unibody macbook pro, the 5,5 version one.

core 2 duo 2,2ghz processor, 160 hd, 2gb ram, nvidia 9400m 256 mb ram.

Ive been trying hard to play diablo with this machine so I started to look for how come my mbp couldn't properly run diablo 3.

The primary symptom is constant lag in open scenery areas, it all slows down.

As I was finding some info, I discovered that this GPU used the mbp RAM. 2 GB is already too little, so if the GPU shares ram, the little would turn out to be useless.

SO I upgraded my ram to 8gb, BUT still, i can't see much of an improvement.

Am I missing something?

Please help!

You could try lowering the graphic settings or even using bootcamp if you're able to use windows.
 
yes, you are missing something. you didn't visit http://www.diablo3.com 's official mac support forum to find out that everyone with this underpowered card is having the same exact issue, and that blizzard is supposedly working on a fix. don't expect to see much of a gain.

edit: look for an update some time tomorrow which is supposed to address this issue.

That's because you have the version with the 9400m, which is an integrated card that's lower performance than even the modern Intel integrated graphics.

I wouldn't expect to be able to run much in the way of modern 3D games, at least not at anything but low or medium settings.

Use this patch and you will be able to play it:

Ram won't do much for performance but
Go into Finder, "Go", press Alt and "Library" should appear. Click that and go to Application Support>Blizzard>Diablo. You should see D3PREFS.txt look for "Hardwareclass" and change it to "1". Greatly improves performance I got about +20-30 fps on my 6750m
