ATI has posted the latest version of its Catalyst drivers. Release 6.4 incorporates Linux support for the chip maker's Radeon X1300, X1600, X1800 and X1900 GPUs, and tweaks video quality on Windows systems courtesy of a few adjustments to the Avivo engine.

In particular, it's enhanced its edge-sharpening and noise-reduction algorithms - according to ATI, this makes for better standard-definition video playback. Another upshot is a 4.9 per cent improvement on 3DMark 06 scores and speeder frame-rates in games likes FarCry, Call of Duty 2, Unreal Tournament 2004 and Half-life 2 - all titles commonly used in benchmark testing, we'd note.
