I am running DAZ Studio now on two Windows 2000 Pro machines with current SR3 Win2K update and on my 32MB MATROX card it is MUCH SLOWER than on my 64MB ATI Radeon. Could be RAM, or maybe the ATI Drivers are better suited for DAZ Studio- (at this particular point in ALPHA!!!) So folks, check your graphics card- it and memory management on your computer will likely make a big difference on different machines running different operating systems.
