Performance Improvements
As with most CATALYST™ releases, the performance has increased in many various situations. Here are some examples observed in CATALYST™ version 3.2.
CATALYST™ 3.2 corrects a problem with 2D applications running in the background that can cause a momentary reduction in framerate (i.e."stuttering") in fullscreen Direct3D and OpenGL games. Specific instances of "stuttering" have also been addressed (e.g. Rallisport Challenge when the sun enters or exits the scene).
Dungeon Siege framerates are improved as much as 24% across multiple products, especially when running at higher resolutions.
Framebuffer read-back performance has improved dramatically (500% or more) in CATALYST™3.2. This feature allows an application to retrieve a fully rendered frame from the graphics adapter and manipulate it or store it in the system RAM or on the hard disk.
Vertex Shader performance has improved dramatically (as much as 100% in some situations) for our DX8.1-class products such as RADEON™ 8500, 9000 and 9100. This brings significant gains to Vertex Shader intensive scenes such as the Battle of Proxycon and the Troll's Lair (both up 15-25% on RADEON™ 9000 PRO).
