Just got a new 1.8 ghz single proc G5 to test out at work... I work in Visual FX and have been on Linux and Winnt up until now. Currently I'm doing some wire and rig removal in Combustion on the PC and I've been eager to test everything out on the Mac before we buy a license. To my dismay the performance is HORRIBLE!! It can't even play 2K 10-bit Cineon files at 24 fps, something that my cheap 2.0 Ghz Athlon can do with ease. The best I can get it to go is 16 fps. I really don't understand this... Combustion writes frames to RAM and then plays them back, why can't the G5 play them back in real time?? Can someone who knows or uses discreet Combustion on both a Mac and a PC enlighten me to the performance of this program?? I really hope this isn't representative of the overall performance of the G5. I mean, I realize that Combustion probably isn't optimized for the 64-bit processer... but right now the 2 Ghz Athlon is slamming this thing. I shudder to think how Maya is going to perform, but unfortunately Alias took down the PLE download from their website until they release version 5 of PLE... ... any thoughts?
