AMD has made available its first new ATI Catalyst driver release of 2010, introducing support for Linux operating system Ubuntu 9.10.

The release, version 10.1 and the first of twelve schedule Catalyst launches this year, also provides Windows users with minor performance improvements - with AMD claiming a 3 per cent boost in popular titles Left 4 Dead 2 and Crysis when using certain Radeon HD 5000-series products.

A wave of bug fixes are also included, but AMD has used the release as a platform on which to promise bigger and better releases later in the year. AMD product marketing manager Jay Marsden states that "over the next few months AMD is planning to roll out some major new features and functionality into the ATI Catalyst drivers".

In the meantime, Catalyst 10.1 is available to download at game.amd.com and the pertinent sections of AMD's release notes can be found below.
