I don't know if it was nVidia drivers or Vue's OpenGL software implementation. In either case, the renders are having many slowdowns.

I did get one run with of VueMark at:

597

So after four night of hard work on this problem, I've come to the conclusion that Vue 64 is not greedy enough with the CPU and RAM. My copy of Vue Infinite 6 is yielding ***to background services.

***I think XP-64 was designed to take better advantage of the multi-processing.  It's my opinion that when Vue sets its render engine on a low priority, the OS takes advantage of this slowdown to run some background services.

In my first installation, there was a slow down caused by excessive hard drive usage and possibly other issues. Now the problem is the windows activation. This annoying program comes up during every VueMark run. As soon as  it does, the interrupted scene's render time doubles. In the Task Manager, I can see Vue using only 90% of the CPU power after this background service has popped up! After I shut it down, Vue goes back to its normal 99-100% CPU usage.

I guess I'll have to activate windows and find out if that helps create more consistency in the render speed.
