Just wanted to post this for anyone else who's happily installing and copying things on their shiny new Mac Pro with 8800 and decides to open up a game.. so they can avoid my initial experience. While I had a bunch of things installing, I decided to open up World of Warcraft and see if it looked pretty on my new display, esp since I'd been playing with most settings on minimum on my old computer. So of course I dive in and set all settings to max, reload it.. and.... NINE frames per second. Ouch. I set the settings to be more modest, and... 12 frames per second. Needless to say, I was more than a little disappointed. I'd installed everything, even done the 10.5.2 update and reboot. What I'd missed was... Apple decided to be idiots and have the 10.5.2 Graphics Update separate from the 10.5.2 Update.. but not only that, the graphics update won't even show until after you've installed 10.5.2 and restarted and then run Software Update again (else you'll wait a week til it checks automatically). After the Graphics update? All settings max (minus the multi-samples), and 90 FPS on 2560x1600 resolution. Sweet! So... run Software Update, get 10.5.2 and all other things installed. Restart, run Software Update again.. have it install the Graphics Update. Restart, and enjoy!
