It is the 9000 Pro (or at least was advertised as such by the manufacturer), but the X600 is not the Pro version. As I said before, the memory speeds reported are very close between the two cards. > Since you said there was no difference in image > quality from having > the graphics acceleration slider down vs. up, it > sure sounds like > *something* (badly written driver?

I said that I don't see a difference visually, but considering we're talking about black and white graphics in PrintMusic/Finale (not SmartMusic), it's a little hard to conclude that nothing is different. > If the > extra work being asked of your X600 is killing > performance and not > actually improving image quality, to me that sounds > like a software > problem and not a hardware problem, especially if > the slowdown is > only in selected applications. Not if certain enhancements are being applied that just aren't terribly obvious. And keep in mind that I said that both cards exhibit a dramatic decrease in speed. It's just a greater decrease in the case of the X600 with all features enabled than with the 9000 Pro with all features enabled. Even with the 9000 Pro the decrease is going from around 10fps down to about 2fps. > When I did my own Googling on this, I found lots of > references to > people who found that backing off one notch on the > graphics > acceleration slider dramatically increased > performance in selected > applications.

I'm pretty positive that I can try this on just about any PC and find that there will be a decrease in performance. We're clearly adding more work for the GPU. Since my cards are similar in memory speed performance, and since we've read that this is a key factor for 2D performance, it's not far-fetched to guess that any extra work repeated many times over could be enough to switch things around. Making guesses at this point is just silly though. The key test would be to get a hold of a computer that has a video card with memory that runs at 3 to 4 times the speed of these cards (which today's best cards have) and see how it performs with two cards of 2 different memory speeds.
