S!
If you can live without the older atioglxx.dll in your IL-2 folder and run Black Death for a few secs every time you start the game, then you can safely use 10.2's or even the leaked 10.3's floating around. It sure is a bit more work, but I do this way, just run track to clear blocky text and after that game runs normally. It is only the first load of 3D that does it in Perfect mode.
I've been running tests so my face is blue to get best settings. Actually you get very good image with game controlled Anisotropic Filtering and using Box 2x with SuperSample Antialiasing, it clears the shimmer effectively. Coastie found this. Also in Color at CCC panel you can fiddle a bit with gamma, I dropped it a few notches and the colors are better too
I slap my conf.ini below, check it and see what you can use
