Official 9.5 Catalyst Drivers Released
 
Better late than than never, eh?
 
The ATI Catalyst 9.5 drivers have now been officially released offering the first official support for the 4770 graphics cards. Dated 15/05/09, the Catalyst drivers have been ready and waiting on the website for four days. Your guess is as good as mine when it comes to the reason behind the delay, but for all those skeptical of the leaked drivers we posted earlier, you can now grab the official drivers from AMD's website.
 

Here are the Release Notes:
 
New Features
ATI Catalyst™ 9.5 – Unified Microsoft WHQL certified graphics driver for Windows 7 and Windows Vista
ATI Stream™
ATI Catalyst™ 9.5 – Unified Microsoft WHQL certified graphics driver for Windows 7 and Windows Vista
AMD has delivered a single unified graphics driver that has received WHQL certification for both Windows 7 and Windows Vista
Meeting Microsoft’s WHQL certification requirements in the ATI Catalyst 9.5 driver for Windows 7 clearly demonstrates AMD’s focus and determination to deliver an extremely stable and robust Windows 7 experience on AMD’s ATI Radeon Graphics accelerators

ATI Stream™
ATI Video encoder update
ATI Catalyst 9.5 resolves a number of issues previously seen in the ATI Video Converter and is supported under Windows Vista 32-bit and Windows Vista 64-bit
Using ATI Stream technology, owners of ATI Radeon™ HD 4800 Series and ATI Radeon™ HD 4600 Series of graphics cards can take advantage of this video conversion tool (found in ATI Catalyst™ Control Center Basic View) to achieve substantial performance improvements when transcoding video files

Performance Improvements

Some measured examples are:

Unigine Tropics DX9 – performance gains of up to 11% for single GPU and ATI CrossFireX™ configurations with anti-aliasing enabled
