I've got a 2.8 GHz Pentium-D DP PC (WinXP Pro) right next to a 2.5 GHz G5 DP Mac (OS10.3.9) and the speed difference is rather noticable to me (Poser 5 and Poser 6 demo). Not with small figures but things like the Mil Dragon, I can rotate the PC version (with full texture preview) almost in real time but the Mac lags quite a bit in comparison. Same sort of thing with the Cloth Simulation. But what really gets me is that in a bunch of render tests the Mac was 20% to 30% slower to render. This is especially odd since the render system was liscensed from the Mac only Pixels3D. I very much agree that the PC has out of memory problems that I don't get on the Mac but I'm not seeing much in the way of crashes on either platform. I'd also reconsider Mac Poser if it ever gets DP support and working Python scripting. Python scripts work in Mac Modo with little in the way of problems, so I know it can be done. And I do apologize if it sounded like I was suggesting that Bootcmap worked on PPCs. What I ment was as soon as the Mactel towers come out I'll get one and probably use just use Poser PC under BC. As always this how it works for me and others mileage may vary (and I'd be interested in hearing them!). Best; Dan
