Blizzard has also done a good job of providing Mac support for World of Warcraft. In fact, the same discs used to install the PC version will work in installing the Mac version of WoW. Unfortunately, Mac WoW performance is nothing to write home about. Performance on a dual G5 2.5GHz with an ATI Radeon X800 XT Mac Edition is less than half of the performance of a single Athlon 64 4000+ and a Radeon X800 XT. The performance on slower video cards is just as disappointing. Blizzard has been active in improving Mac WoW performance, but the gap remains to be nothing short of huge. Mac OS X has never been known as a gaming platform of choice, but Mac users should at least be able to run the games to which they do have access at comparable frame rates to their PC counterparts. Regardless of whether the Mac WoW performance issues are the fault of Apple, Blizzard or the GPU vendors, they need to be fixed if any of the responsible companies actually care about that user base. WoW is quite playable on the Mac - it's just noticeably slower than on the PC.
