I'm having huge problems playing the game. The fps, with a group of monsters, drops down to 5-10 (group play-impossible). I tried everything blizz recommends in "support" but it got me nowhere, tried everything I could find on forums (disable trilinear filtering...). I also tried every combination of graphics, putting it down to 800X600, and IT WAS THE SAME fps drop/stuttering as on native 1440X900.
What I'm trying to say is that I don't get any changes no matter what I do. I should be seeing some changes to gamplay with everything low/off and 800x600 res, right?
So, my question is:
1. is it a problem with the game
2. is it a problem with my computer, and I need to make some hardware changes (which?)
3. would boot camp solve my problems (windows extremely expensive)
I would be extremely grateful to anyone who might have some insight and help solve my problem. Thank you

Your laptop has two sets of chipsets available, and may be inadvertantly switching between the two due to either estimated battery life, energy saver settings, or your graphics switching setting.
For your Energy Saver settings, you should have at most either "Put hard drives to sleep" or "Put display to sleep" activated, but not both. You should also never use the Sleep option in the Finder's menu or by using the keyboard combination CMD-OPT-F12, as the puts the system completely to sleep. There is a known bug in both Liion and Mountain Lion where OpenGL performance takes a nosedive after sleep has been used at any point. The only way to fix this is to reboot, or switch to a different resolution and then switch back to the resolution you want before launching any games.
As for graphics switching, you want to set it to always use the nVidia 320M discrete GPU. The instructions are in the article linked below:

Try these settings and see if it helps resolve your issue.

I appreciate the suggestion, but it's not it, I'm a "veteran" in trying to make diablo 3 work on mac.
In the end I had to succumb to installing windows 7 on boot camp, and it's like I bought a new computer! Max res (1440x900), high everything (including shadows) and stable 30-50 fps.
