I wouldn't say that about the ATI driver folks. Back when I was running a small team at MSFT, we were the first serious users of the then-new WPF text rendering APIs that were built on top of the new driver models. So, we hit bugs. The ATI on-site folks were awesome. Usually, they had already found the bugs and had a patch that was going through stability testing. When they didn't know about it, one of them would come by, usually within a couple of hours, and connect up a kernel debugger or whatever else was needed to track down the bug and turn us around a fix. I still prefer AMD video cards to this day based on that experience.
