Catalyst 9.1 WHQL benchmark review
AMD's Catalyst 9.1 WHQL has been late and came just in time for a January release. PC Games Hardware tests if the long development results in better performance.
Catalyst 9.1 WHQL benchmark review: Introduction
With a noticeable delay AMD released the Catalyst 9.1 WHQL on January 29. As usually the package of CCC (Catalyst control Center) and drivers is available for download in versions for Windows XP and Windows Vista.
Although the 9.1 is a WHQL certified driver, which had to pass Microsoft's quality tests, it still contains the AF Bug known from the 8.12 Hotfix - the problem is also mentioned in the Release Notes. But they don't list the D3D10 workload optimizations for multi-core processors which have also been introduced with the 8.12 Hotfix. Our benchmark results on the next page reveal how fast the Catalyst 9.1 WHQL is compared to the 8.12 Hotfix and the 8.12 WHQL.
