AMD’s driver team is on a roll at the moment. The guys on the Catalyst team regularly churn out a new driver every monthy, but Catalyst 9.4 has turned up just three weeks after the release of Catalyst 9.3.

At the top of the new driver’s feature list is a new Auto-Tune feature in the Overdrive section of the Advanced Catalyst Control Center. As you would expect, the object of this tool is to do automatically find decent overclocked settings at which your ATI GPU will run stably, saving you the trouble of trial and error.

Of course, previous ATI Catalyst drivers also featured an Auto-Tune facility, but the new one works slightly differently. While previous versions simply displayed a dialogue box as the driver experimented with different clock speeds, the new Auto-Tune tool displays a full-screen graphic (pictured) in order to fully test the 3D clock speeds when running in full-screen 3D mode. There’s nothing revolutionary here, but it’s still a neat feature to have in the driver. According to AMD, the new Auto-Tune facility was specifically designed for Radeon HD 4000-series GPUs.

As you would expect, the new driver also features a few bug fixes and adds support for the Radeon HD 4890. The bug fixes include fixing the Compute Abstraction Layer (CAL) under Windows XP, meaning that XP users can now fully take advantage of AMD’s Stream technology.

As well as this, AMD also says that the new driver fixes problems with flickering in World of Warcraft when setting Shadow to Medium or High using CrossFire. Plus, resolutions above 1,024 x 768 will now apparently go to full screen more properly when using specific HDMI displays that previously had problems.

You can download Catalyst 9.4 now from here. Are you interested in AMD’s enhanced Auto-Tune feature, or would you rather use another overclocking tool or go through the process yourself manually? Let us know your thoughts in the forums.
