Poor performance on Mac Pro

Mac Technical Support
I have had this problem for over half a year now, and it's still persistent. I am unable to get over 30fps on graphical settings over Fair quality. I currently have it set to Fair quality, with a few tweaks here and there to other graphical settings but even so I still get occasional hangups/popins graphically. I have tried pretty much everything I can think of to fix this issue, such as re-downloading patches, re-doing the wtf folder, reset sram, etc. Recently I copied my WoW folder onto an external drive and put it on a new iMac (with no upgrades/out of the box essentially) and the game ran smoother on it!

I have my WoW folder running on the boot drive, a 2-month old 240gb Mercury Electra 6G solid state drive. With WoW running (64-bit if that matters), it is using 53% CPU, 5.5% user, 1% system, and 94% of CPU idle.

That machine should be way higher. something is differently wrong.

do you use sleep mode on that machine instead of shutting it down? like all macs on 10.7 or higher. sleep will tank performance.

I have an even older mac pro that sees 60fps on good settings pretty much everywhere except for highly crowded areas and raids. Then fps drop down to teens. But that's expected with a 2008 cpu and wows old cpu code. Your cpu is 2010 though and should do better then that in those situations. so maybe that's where you see 30fps? if so that's probably about right actually.

but anywhere else you should be rock solid 60fps at probably high or even ultra.
If I'm out in the middle of nowhere, I can get about 35 or so fps on High, fluctuating by 5 or so. Even in 10 man raids, on fair settings, I'll still get hiccups and not a constant 60fps (which is max threshold I have it set at).

I have tried all of the suggestions, without addons on,
Reset UI
Repair World of Warcraft
Reset System Management Controller (SMC)
Delete Data/Cache Folder
Repair Disk Permissions and Repair Disk
Reinstall Drivers (Combo Update)
Perform an Apple Hardware Test

I'm honestly starting to thing that it may be a hardware/compatibility issue with the game itself. However, I have indeed noticed that even on Fair settings my PCIe slot would heat up to 80-85 degrees C, so I had to install a program (SMC Fan Control) to manually crank up the min fan speed so my card wouldn't die from overheating... the fan runs at a constant 2000rpm, with avg temp around 75 C (compared to about 55 C when WoW isn't running).
I'm having the same issues on a MacPro (NOT the MacBOOKPro since people seem to think we're always talking about the laptop) and I've gone from 106fps to 11fps from 5.0.x to 5.1.

Running an PC ATI 6870 on 10.8.2 @ 2560x1600 with addons turned off (off/on, doesn't make a difference). I'll try installing Windows 7 via bootcamp and play that way for now but so far the framerate is crap.

Not sure how to provide a dump or any logs for bliz to take a look at?
Omegal, can you give me an idea of your settings? i have a late 2008 MBP running 10.6.8. I have all settings on low for WOW, I can' get above 33 FPS and in Pandaria it drops to 22 FPS. Any suggestions would be appreciated.

Lockstar, we are on Mac pros, not macbook pros. i have a 2008 mac pro which is getting much better performance than their 2009 and 2010 mac pros for some reason. which is how i know something is just wrong on their end. especially considering using same gpu even as OP.

I'm on 10.8.2 now but i never had probelm on 10.7.5 either. in fact. 10.7.5 should be ahead of 10.8.2 for the mac pro since 10.8 had opengl regressions and no improvement to ati 5000 series drivers to counter it (unlike the 2012 macs which benefit highly from 10.8.2 despite the opengl regressions).
