ATI Catalyst 9.3 Released
AMD today released the latest version of their ATI video driver, Catalyst 9.3. The key addition with this release is official support for Windows 7, in the form of a unified graphics driver for Windows 7 and Windows Vista. As part of supporting Windows 7, Catalyst 9.3 supports WDDM (Windows Display Driver Model) 1.1 for all ATI Radeon HD 4000, HD 3000 and HD 2000 series of graphics cards. According to AMD, "this new WDDM 1.1 support utilizes DirectX 10 rather than DirectX 9 and can cut down your GPU memory usage by half when opening up multiple windows thereby enabling increased performance."
AMD have said the driver brings performance benefits in several cases where framerates are CPU limited and using ATI Stream technology, owners of the ATI Radeon HD 4000 Series, ATI Radeon HD 3000 Series, and ATI Radeon HD 2000 Series of graphics accelerators will see a performance boost in their Folding@Home scores when running the latest Folding@Home client. AMD only documented one performance improvement in the release notes:

hehe...
I love my 4.2Ghz P4 :rockout:
I tried modding the 9.3's with the mobility modder v 1.1.1.0 and it was a no go.:banghead:
So it's back to 9.1 for me
Release notes
Before i install catalyst drivers in Windows, DVI works.
As soon as i install them and reboot, screen turns black (lost signal) right before windows loads up. I unplug DVI and use VGA adaptor and Voila! I can see my desktop again.
This is a known problem! AMD Forum has a long list here.
Have you tried to wait a bit (until Windows starts to load) and see if it comes back again? If so, it's the same as me and i have it functioning like this, otherwise it's a different thing then what i'm referring to.
Mine, sometimes the monitor is OK and i can see the boot info but others, it has the light on the monitor blinking (black screen) but, just after windows starts to load (sometimes, a bit longer), it turns itself on and stays on until i either shut it down or power saver kicks in.
Will have to try drivercleaner and driver sweeper again see if that clears it up this time...
