This release of Catalyst 7.8 introduces an enhanced version of ATI Overdrive
for the ATI Radeon™ HD 2600 Series and ATI Radeon™ HD 2400 Series. Users can now
Over-clock both GPU engine and graphics memory clock speeds in single and
Crossfire mode. There is also a new stress test application. However, in
CrossFire configuration, the OverDrive 5.0 test application will run only on
first GPU and any unlinked GPUs. Missing support is due to a limitation in
current driver implementation and will be resolved in upcoming driver release.
There are also performance improvements in Lost Planet DX10 with anti-aliasing
improves 11% or greater on Radeon HD2900XT, in 3DMark 2006 and 3DMark2005 as
much as 6% on Radeon HD2600 and HD2400 and Serious Sam 2 with HDR enabled
improves as much as 14.5% on Radeon HD 2xxx series.
