We're glad to offer you the latest Catalyst driver, now reaching version 12.1a, still in preview mode. Being already the second 12.1 preview driver might very well mean that the final stable version is expected really soon.
The major update concerns Rage, as the latest version of the game brought some troubles with the old 12.1 Preview driver. Rage is said to perform 5% faster with the present version of the Catalyst, while texture corruption issues introduced by the latest game update are being addressed.
Map switching generated errors and even game crashes when used with both 32-bit and 64- bit systems, but AMD says that these issues have been resolved in the 12.1a Preview driver. Finally, you should note that all the features present in the 12.1 Preview are also present in the 12.1a edition.
While waiting for the final release of the 12.1 Catalyst, you can
download and experiment with the 12.1a Preview, for XP, Vista, and Windows 7.
