AMD has released the AMD Catalyst 12.6 Beta, available for
download here. With the release of the Catalyst 12.6 Beta driver, AMD also
confirmed earlier reports that the company would move away from its Monthly Catalyst
release plan and released drivers for the Windows 8 Release Preview.
"Our goal is to ensure that every Catalyst release
delivers a substantial benefit to our end users; as we have today with
the release of the Catalyst 12.6a Beta," said David Doel, AMD marketing team. "We will still continue with the
Catalyst naming convention; Catalyst: Year.Month., You just won’t see a
new driver every single month. We are confident that this will only
benefit the end user; you’ll only need to upgrade to a new Catalyst
driver, when it makes sense" he added.
AMD also introduced the AMD Issue Reporting Form.
The company made a number of improvements to the older Catalyst Crew Feedback
form, making it more comprehensive. AMD said that it would review every
report posted and investigate every issue encountered.
