All you Radeon owners should head on over to
the AMD/ATi website and grab the new Catalyst 9.5 drivers. The link to the patch notes still points to v9.4 PDF release notes, so for now there's no word on what's changed. Grab them if you need them!
Update: The drivers bring full support for Windows 7. Otherwise, the 9.5 Catalysts are supposed to improve performance in Company of Heroes and BattleForge by up to 10%. AMD also claims it has resolved "a number of issues" with the ATI Video Converter.
TweakTown posted ATI Catalyst 9.5 Vista Driver Analysis:
The latest drivers don't show a whole lot for the HD 4890 and HD 4870 X2. As for the HD 4850 we see performance drops in many games and by a good chunk. For the most part we wouldn't recommend HD 4850 users upgrade to the latest set of drivers.
