Obviously, 12.7 Beta is faster than 12.6 WHQL; 12.7 Beta June 26 comes 4th and 12.6 WHQL 8th in our top drivers list.
Based on the release notes for 12.7 Beta you get the feeling that this driver would be awesome but after you test those “improvements” for yourself you see that things aren’t pink. We should have seen improvements with 3DMark 11, Battlefield 3 and Crysis 2 but unfortunately that didn’t happen (at least with a HD6950), performance was actually slightly lower…The only game that was indeed performing better is Skyrim but most people have game breaking issues that must be fixed ASAP.
I still have that feeling that nothing really changed since AMD made their announcement regarding drivers schedule modification and if you really want to feel a change (fixes, improvements etc) with each driver released you need to get a HD7900 card. After AMD made a compromise in dropping support for pre-HD5000 cards I expected better support for HD5000 and HD6000 cards, which isn’t happening at the moment…
I can’t refrain from saying that Shogun 2 is unplayable on HD7900 cards due too freezes and lock-ups yet AMD focuses on performance…
And if that isn’t enough rant, AMD still focuses on 2-3 year old games instead of addressing issues with earlier ones which should be in my opinion their top priority…but AMD likes to praise themselves: http://blogs.amd.com/play/2012/06/28/the-new-catalyst/
