The fans should come on, as Diablo III is a very demanding applications, more than WoW/SC2 due to graphics. You should be able to hear them.
Now, for the 320M, you should be able to try to drop your hardware class to 1 in the D3Prefs file and limit your Max Foreground FPS in between 25-30. This should lower the heat, and may it not so hot, as this is an integrated card.
I personally have a 320M for my Mac Mini and I play Diablo 3 with FPS limited to ~23. I can play at native resolution with shadows on low very well. Heat isn't an issue with these settings for me. You may want to see if that helps.
I expect the fans to come on, as it IS a demanding game as you have said. I'm just wondering why the fan rpm has increased so much since the newest update. Before the update, the game ran fine at a decent temperature with the fans spinning nowhere near as fast, so I guess I'm just wondering what changed and how I can change it back.
I don't have the 320M, I think the guy that posted after me did though. I will try the hardware class change though, but my FPS are already lowered to the values you suggested. It may be a few days before I get back, as I am on vacation, but I'll keep you updated on the issue.
my friend... look, first off, you really dont seem to know a damn about what you are talking about...
i am not doubting that the patch made things worse for you, nor that blizzard messed up the mac client. but still your ignorance is troubling me.
a sticker telling you "works on mac" is what you base your claim on?
a mac is still a computer and relies on hardware. and hardware changes and gets replaced/updated in newer iterations of macs.
so there is no such thing as "works on mac".
also you are running the game without a dedicated graphics card and are pissed about bad performance/heat issues?
please invest some time into research, before buying your next computer and dont just expect everything to work because you are assured of it by a sticker.
This isn't the place to argue the Mac vs PC debate, but suffice it to say that I have done plenty
of research on Macs, and am not sure where you think I am "ignorant" on the subject. There is
such thing as "works on Mac" because I have plenty of programs that run flawlessly. And you're right, I do expect that if something is advertised as supported, I expect it to work (false advertising?). I wouldn't buy a PS3 game and expect it to work in my Xbox, and the same logic applies. None of my previous laptops (PCs) had dedicated graphics cards either, and they ran games fine, so that really isn't the issue that I'm having. But again, this isn't the place to debate this, so if you're so against Macs, don't visit the Mac
Technical Support forum, and don't assume that I haven't done plenty of research on the computer I own.
