Graphics accelerator problem

[JRichizzle]

Hi,

My graphics card is pooping out on me during motion simulations. I am updating HEAD_POS with a continuous timer to simulate smooth (passive) linear translation of the eyepoint through an environment. I use hotspots to update the position of 3 different segments of the environment in a "leap frog" manner.

The program freezes at variable times during this process and the following message appears:
"VPU Recover has reset your graphics accelerator as it was no longer responding to graphics driver commands. Please tell ATI Technologies about this problem."

Any clues as to what is going on?
