Triumph! Success!
Here we go guys.
You '09 iMac users with ATI cards might get away with something cool that doesn't require cloning a drive.
Disclaimer: You mess up your Mac, it's not my fault.
Thanks: To those who suggested how this could be done in the first place. Yes, Pacifist and the download for the new Imacs does it.
Thanks also to Barefeats who found out that these drivers really are the bees knees after all.
How: Exactly as suggested.
Highlight EVERY ATI entry in System / Library / Extensions of the file MacOSXUpd10.6.4foriMacMid2010.dmg and select install from the menu on the top left of the pacifist masthead.
But you want to see the results right?
First, Before:
2560x1440 framerates with the old ATI drivers:
A pitiful example. What the heck?
The best I could manage after a few tries:
Trying it at HD resolution:
1920 x 1080 framerates with the old ATI drivers:
You get the idea.. It's better but you have a 2560x1440 display, who wants to play a game at 1920x1080?
AFTER THE CHANGE TO THE NEW DRIVERS!
2560 x 1440 framerates with the new ATI drivers:
Okay, that's a lot better.
1920 x 1080 HD framerates with the new ATI drivers:
MUCH BETTER!
Better all around.
Thanks very much to whoever suggested this. It wasn't that hard and it was a bit nerve racking potentially bricking my new baby but...
Note: this applies ONLY so far as I am aware to the 2009 refresh iMac machines with ATI cards.
My machine is a Corei7 27" with 12 gigs of ram and stock 1 TB drive.
Your mileage may vary.
Your mileage might get better results than mine.
Your mileage might brick your machine.
Questions? Ask.
Disclaimer: Apple might push out an update rendering all of this scaryness unecessary very soon. Then again they may not.
One more just because:
