AMD Catalyst 11.1a Hotfix

AMD has released a new build of their Catalyst software suite. This particular software suite updates both the AMD Display Driver, and the Catalyst Control Center. This unified driver has been further enhanced to provide the highest level of power, performance, and reliability. The AMD Catalyst software suite is the ultimate in performance and stability.

Catalyst 11.1a Hotfix brings the following features:

    AMD Radeon HD 6900 and AMD Radeon HD 6800 Series:
  • 3DMark Vantage improves ~7%
  • 3DMark06 improves ~3%
  • Call of Duty Black Ops improves ~20% at 4xMSAA and up to 35% at 8xMSAA
  • Riddick Assault on Dark Athena SSAO performance improves ~20%
  • Unigine Heaven OpenGL performance improves ~10% at moderate, 30% at normal and 100% at extreme tessellation levels

  • AMD Radeon HD 6800 Series:
  • Aliens vs. Predators improves ~9% at 2xMSAA and up to 20% at 4xMSAA
  • Batman Arkham Asylum improves ~4%
  • Crysis Warhead improves ~2-4%
  • Metro 2033 improves ~28% at 4xMSAA

  • AMD Radeon HD 6900 Series:
  • Battleforge DirectX 11 performance improves as much as 6%

AMD Optimized Tessellation
The Catalyst Control Center includes an early prototype of some new tessellation controls. Our goal is to give users full control over the tessellation levels used in applications. The default selection “AMD Optimized” setting allows AMD, on a per application basis, to set the best level of tessellation. The intention is to help users get the maximum visual benefit of Tessellation, while minimizing the impact on performance. Currently no applications have been profiled, so the “AMD Optimized” setting will be non-operational until further notice.

The “Use Application Settings” option gives applications full control over the Tessellation level. Users can also manually set the maximum tessellation level used by applications with the slider control

The long term goal for the “AMD Optimized” setting is to use the Catalyst Application Profile mechanism to control the AMD recommended level of tessellation on a per application basis. AMD’s intention is to set the tessellation level such that we will not be reducing image quality in any way that would negatively impact the gaming experience."

This is really odd because 11.1 only appeared on ATI website today, well yesterday now but when you view the software within Catalyst 10.11...? How come 11.1 is showing up as 10.11...? What happend to 11.0 am I missing something here or is anybody else showing 11.1 as an official download on

Release Notes:

[Quote]Catalyst Version 10.11
Provider ATI Technologies Inc.[/Quote]

Me is very confused

The download has been updated. The original AMD Catalyst 11.1a Hotfix had a problem with tessellation on OpenGL applications. The updated build includes a fix for that issue.

Ati has been so dumb Lately
10.10e's or something had Morphological AA for 5870's
Then Drivers after that nothing
Why cant they release ONE good driver that doesnt need multiple hotfixes

Installed the 11.1a and performance went down from the 10.6's Cats. The 10.6's have been the best drivers for me so far. That being said the 11.1a so far haven't given me any issue what soever.
Running Unigine Heaven Benchmark
FPS: 83.5
Scores: 2104
Min FPS: 12.4
Max FPS: 153.6

Cats 11.1a
FPS: 78.5
Scores: 1979
Min FPS: 25.4
Max FPS: 126.7

Look dood, if you were even remotely smart, you'd rather have an average 78 with minimum 25 than an average 83 that sinks to 12 and fvcks up your gaming.

I so hope these drivers are better than 10.12's!! I had an awful time with them on two separate machines one running 5850's CF and the other 5770's CF. Of all the recent drivers that ATI/AMD put of for the graphics over the last year the 10.12's where horrible. Ok my rants over going try the 11.1a's.

I wondered if I was the only one. 10.12 gave me random BSOD's with my 5770 for no reason. went back to 10.11 with no problem. Note this is the first time I ever had a BSOD on Win 7

Maybe that explains the random BSODs I've been getting lately.
