Did you run a driver cleaning tool in safe mode before installing? Did you go through the registry to see any leftover keys were there? Just because the drivers offered no performance benefit to games doesn't mean they didn't do anything. They fixed a lot of issues that people had, like stability, incompatibilities and other errors not including gaming.This 9.2 is useless. It offers no performance benefit for "normal" games and it also breaks Microsoft Flight Simulator X.
It can't start anymore - it crashes with error 1033. Going back to 9.1 or 8.12 Catalyst drivers fixed everything.
Steer far and clear of this turd (9.2).
