Quote:  The only thing I changed from the global settings was turning the "threaded optimization"  OFF. Turning it ON seemed to preserve stability as well, however, camera tracking was VERY slow and choppy, and my cpu usage never dropped below 50%... Turning it OFF, on the other hand returned poser to it's normal smooth operation.

TikiGawd, When you say global settings, you're referring to the video card's global settings, not Poser, correct?

Not much time to get into it tonight, but I'll have a look at what kind of options I have tomorrow. ATI cards drivers have a Catalyst Control Center, and I know there are some 3D options available. Fingers crossed, hopefully it will work for me too, those crashes really are frustrating.  Thanks again, much appreciate the help.
