I installed the new Catalyst drivers for my video card yesterday, and today I noticed that several of the visual effects for Windows were no longer functioning. I couldn't find where the settings had changed, but I finally figured out that my Windows Experience scores for graphics were down to 1.0 for desktop and 2.0 for gaming graphics. After I re-ran the Windows Experience Index assessment, it was all okay again. Is that the norm for when you install a newer version of a video driver? It didn't seem like that happened before on Vista.
