I think if you give CoD a try with the lastest Beta patch you'll find that most of the previous problems are fixed. I find the frame rate much improved, the legacy graphics issues cleaned up and biggest improvement for me is the memory/CPU assignments that seems to have cured the crashing problems. I can easily run a sim in mission builder with up to 80 planes, lots of static and mobile features on the ground and not have some much as a stutter unless I get tight with a large group of bombers or fighters.

As for the 12.8 Catalyst, don't know why it won't work in my machine, but the problems was cured as soon as I rolled back to 12.6.
