ATI Technologies has released a new catalyst driver package for its Radeon 9559 and higher graphics cards. The new release comes with performance improvements due to improved compilers and optimisations.
ATI video cards with 256 MB video memory improved performance by up to 22 percent on X1000 series cards. Lower end ATI Radeon X550 and higher graphics cards receive improvements up to 30% in Call of Duty 2 when running resolutions of 1280x1024 with anti-aliasing.
Also ATI claims that the performance improvement is shown most in X1800 and X1900 series graphics cards.
Improved shader compiler and transform engine optimizations have led to many significant performance gains in OpenGL applications across the entire Radeon X1000 series of products. These include:
Doom 3 performance improves as much as 6.5%
Quake 4 (v1.2 or higher) performance improves as much as 18%
Chronicles of Riddick performance improves as much as 20%. Average improvements of 5-10% are commonly seen
