How The ATI Catalyst Driver Has Matured Since The RV770 Launch

"It has been two years since the ATI Radeon HD 4800 (RV770) series launched so we have gone back since that monumental hardware launch and have re-tested each Catalyst driver release since then to see how the performance has changed for the ATI Radeon HD 4850 graphics card. The Catalyst driver has certainly matured over the course of two years in speeding up the OpenGL performance with this hardware along with bringing new features to their proprietary driver, but it is not exactly smooth sailing.

"The ATI Radeon HD 4850 and ATI Radeon HD 4870 graphics cards based upon the RV770 GPU had launched in June of 2008. Not only was the hardware great, but it was met by an evolutionary leap in their Linux support. This was the first major ATI product launch that was greeted by same-day Linux driver support (and all succeeding launches since have shared the same level of support) and many other advancements on their once widely criticized Linux side. In the months that followed the Radeon HD 4000 series launch they went ahead and unleashed CrossFire on Linux, provided OverDrive support for GPU overclocking, and have nearly reached feature parity with their Windows Catalyst driver. While in terms of features they may be close to a parity, today we are investigating how the Linux Catalyst driver performance has changed over the course of the past 24 driver releases."
