With all due respect ATI seems to be conducive of this type effect even in other 3D apps. For some reason ATI is not as Effective for 3D as it's counterpart NVidia. I really don't know why cause ATI is best for Vid games, (Fast Vid Games), too, but it is just not as good with 3D itself. The other forums pop up with this type problem and others from time to time and it is usually ATI or not enough RAM and I am assuming you have plenty of RAM.

I would rather be Politically Incorrect,
Then have Politically Correct-Incorrectness!!!
