I know I mentioned something similar when upgrading to Catalyst 11.11, which turned out to be a bug in my code :-/, but there definately seems to be a significant drop in performance using these drivers (-18%).

Apparently others are experiencing a similar drop in performance:

I realise these are preview drivers only, but it is strange and concerning given the degree of performance impact...Unfortunately I'm going to have to wait for the final release before I can restore performance as re-installing 11.12 doesn't revert the problem (obviously the uninstall didn't remove everything).

Has anyone else experienced these same performance drop using Catalyst 12.1 preview drivers (Win 7 64bit)
