After two previews of its 10.4 driver, AMD has finally released a full WHQL-certified version of its April driver. The new driver supports all Radeon cards from HD 2000 series onwards, but all performance improvements are reserved for, as you could have guessed, HD 5000 series cards.

The new driver features new video enhancements as well, as it comes with H.264 Level 5.1 support with the ability to playback 5.1 level streams on all supported players as well as the ability to playback high resolution content (4Kx2K).

Other noted novelties include enhanced support with performance improvements for the Windows 7 Drag and Drop video converter, support for new H.264 file formats, and an option for enabling/disabling GPU acceleration in ATI CCC.

The performance improvements are limited to the HD 5000 series cards and they only include S.T.A.L.K.E.R. Clear Sky with up to 6 percent on the HD 5970 and up to 3 percent on both HD 5800 and HD 5700 series cards. We guess that the Battlefield Bad Company 2 fix is also present in this final release as well.
