Hi Williamsheil. Good points. Some of my frustration with Windows -and I have been running Windows ever since NT3.1 (now there was unstable!) has been the resources the OS actually take to run. Today I have been playing with my latest toy(new PC) It has a Matrox Parhelia 128MB workstation card. The device driver has a .NET interface - it needs huge resources from my system that I need to use Poser. A comparison - ATI radeon driver 3,244K, Matrox Driver 22,148K. I agree that poser puts extra-ordinary stresses on any system. I do not know if Intel Hyperthreading technology or AMD's Hammer would actually improve things as far as bus width is concerned. I am somewhat surprised that CL does not take into account some of the technologies that the graphics cards are beginning to incorporate into their engine (hardware displacement mapping and such) We seem to be reaching a point within the process that Poser is using the CPU/RAM for rendering operations and leaving a specialised,made for the job rendering engine quiescent. dbutenhof Thanks for the update. Sad that is probably going to be carbon based. kawecki That was my understanding of the problem. PaulC
