    A Message to VMware Fusion Users with Macs that have ATI Graphics Cards about Apple's Mac OS X Update 10.5.7

    Apple released the Mac OS X 10.5.7 Update yesterday, and I know many of you are eager to try it out. However, if your Mac has an ATI graphics card (MacPro or iMac), and you rely on VMware Fusion's 3D Acceleration feature to run either Windows games or other Windows 3D applications in your virtual machines, we recommend that you do not upgrade your Mac to 10.5.7.

    We are making this recommendation because the ATI driver in Mac OS X 10.5.7 breaks the 3D acceleration feature in VMware Fusion. You will likely see issues ranging from slow performance, to incorrect rendering, and even crashes, when you run your 3D applications in a Windows virtual machine on Mac OS X 10.5.7.

    Both Apple and ATI are aware of this problem and are working to correct it in a future software update. In the meantime, if you have an ATI graphics card in your Mac and need VMware Fusion's 3D features to work, we recommend that you do not upgrade to Mac OS X 10.5.7.

    Stay tuned to the Team Fusion blog and follow us on Twitter for the latest updates.

    Most of us simply boot into Windows through Boot Camp to do 3D gaming on a Mac. 3D gaming performance under VMWare is atrocious.

    I have the previous generation iMac with the nVidia 8800 GS, but I do the same thing. For the best Windows gaming performance on an iMac, Boot Camp is the only way to go.
