You're right ernyoka 1. I have 3 computers and have tried the program on all three. Read post 3 above and you will see that I encountered the same thing you did which is why I believe the video card has a lot to do with it. All of my machines are desktops....not a laptop in the bunch. The brand new Compaq Presario with the 2.7 ghz processor is significantly slower at rendering than the PIV 1.7 ghz machine. Both have the same amount of DDR Ram (512 mb). The difference: The Presario has an intel video chipset on board and the PIV has an NVidia GEForce 2 MX 200 video card with 32 mb of ram independent of the system. Even the old PIII with 256 ram runs the program better than the brand new Presario. I can't even use the camera tools on the Presario......they barely move anything.
