I have a white 2.33 GHz 24" iMac with 2GB of RAM, system 10.4.10. Up till now it's played WoW perfectly with gorgeous graphics. Recently a patch came out that seems to have screwed up a TON of technical stuff, and I'm no exception. I posted to their Mac boards regarding the screen tearing, texture problems, and graphical artifacts I'm seeing, and the only response was that my artifacts are probably because the computer's overheating. I find this really hard to believe considering I had a problem with my old computer overheating and the symptoms were completely different, plus this coincides exactly with the patch and hey, what a coincidence? But I thought I'd ask here -- is there any way to tell whether the computer is running hotter than it ought to? I know about one or two of those widgets that show you the temperature and fan speeds, but I don't know what the benchmarks are for iMac performance, nor what's "too high" when playing a game. Thanks for any help you can provide. I tried to search but got back too many responses to find the answer.
