Appearently you haven't been reading various message boards where hoards of people are complaining about the Catalyst driver support. Using Catalyst 3.8 drivers the game crashes randomly. Documentation states to use 3.7, ok fine, so you switch to 3.7. Here is the problem, when you are in a nearby explosion and your bell gets rung (or the death sequence) the graphics are supposed to go all blurry. With Catalyst 3.7 drivers the graphics are corrupted.
You're absolutely right. I didn't read those. I use a Radeon 9700 Pro and use the Catalyst 3.7 drivers so I didn't have a problem. Since I do not have the time or desire to read the drivel of every single gaming message board out on the Internet I can only test it on my one lone machine and go from there.
Also, I did not have graphic corruption problem on my machine using the 3.7 drivers that you discuss. The bell ringing effect worked fine.
