Download Driver For Omega Catalyst 2.5.76

Spread the love

A new set of ATi Radeon Omega Drivers can be found on, version 2.5.76. They are based on ATi’s Catalyst 4.9 driver and the fact that Omega has taken so long to tweak them is because he lives in Puerto Rico. Tropical storm Jeanne has wreaked havoc there, which has slowed things down a bit. Omega emphasizes that you have to read carefully during the installation, because he gets a lot of people who blindly click on next, next, next and then knock on his door because the drivers would not work correctly. The changelog for this release looks like this:

Changes in this release:

  • Based on the official Catalyst 4.9 drivers.
  • Removed ATITool from the package, it had many bugs and disabled a lot of stuff, like DVI support and DDC. If you have it installed, I recommend that you uninstall it before installing this set of drivers.
  • Re-Enabled Overclocking Anti-Protection, it was missing from last release, sorry.
  • Modified the ATI CP, now the Omega Drivers will use a built-in, special RadLinker version with the following features: (some new, some old)
    • Uses NO resources.
    • Some new settings for both D3D and OGL.
    • Can set Automatic Per-application profiles for OGL & D3D applications.
    • Desktop Gamma is working and NOT resetting to default after exiting a game.
    • Integrated Overclocking.
    • No need for Gamma Hotkeys anymore since you can now set an individual Gamma value for each game in their profile and done.
    • This new CP was made in conjunction with ChrisW, maker of Radlinker, as an exclusive feature for the Omega Drivers and we will keep adding features in future releases.
  • Modified driver installation/uninstall procedure with several new automatic features.
  • Since RadLinker is now a vital part of the Omega Drivers, it will not be an option to select during setup anymore, it will now automatically look for and uninstall ANY previous version and replace it with the new one.
  • Now, when uninstalling the Setup tools from the Omega options in the Start Menu, you will also have the option to uninstall the Display drivers in one pass.

Known bugs:

  • Laptop video playback problem still here, see notes.
  • Hibernation and Standby are not working properly, I’m working on a fix.
