As with most Catalyst® releases, performance has increased in various situations.
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
Prey performance improves as much as 16%
Optimizations made to ATI's graphics memory manager have led to significant gains in DirectX applications that make heavy use of graphics memory on 256MB ATI graphics cards:
3DMark06 performance improves as much as 22% on single ATI Radeon® X1000 series cards with 256MB of graphics memory at 1280x1024 and higher when anti-aliasing is enabled. The largest gains are found on the ATI Radeon® X1800 series and ATI Radeon® X1900 series of products
Call of Duty 2 performance improves as much as 30% on single ATI Radeon® X550 cards or higher with 256MB of video memory at 1280x1024 and higher when anti-aliasing enabled. The largest gains are found on the ATI Radeon® X1800 series and ATI Radeon® X1900 series of products
