I've just purchased a brand new 2008 Mac Pro with the ATI 2600 XT video card and everything seems to be fine except when I tried to run the Cinebench 4D demo program (not the benchmarking program). When I try to launch the program (it installed fine), I get some garbled text on the splash screen and after the program loads I see mostly black areas where the tools would be, making the program basically unusable. My buddy tried it on his iMac and Macbook Pro and had none of the issues I was having. One thread on Apple's forum suggests that it's a Leopard bug with the ATI card and Cinebench 4D. I'm trying to determine if this is indeed a driver issue or if it's a faulty card. Can someone out there with a Mac Pro and ATI 2600 XT download the Cinebench 4D program and see if it loads and works right? Here's the link to the downloads page: http://www.maxoncomputer.com/download_demo.asp Thanks.
