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:

* Lost Planet: Colonies gains up to 20% on 4800 series products, and up to 50% on 4600, 4500 and 4300 series products

too much fail in ATI

Nice~~Downloading now, thank you for the update~

tested, but the look like they didn't fix the powerplay for 4870x2, in idea the 2nd GPU/MEM at 750Mhz/900Mhz, this should be drop to 507Mhz/500Mhz.

disappointed.

yup.. it happended to mine X2 too.. the onli way to get it back to 507/500 is to run the fur benchmark for a couple of secs full screen ...

mine 4830 when idle 500/750mhz..is that normal bro..??

sure normal, anything wrong ?

ya, that is the way, so let give hope on next driver 9.4.

This version improves some of my game performance/stability

I want to see how's Cat 9.4 will be...

ati 9.4 version will be superb mostly support 4890 latest driver

kinda dissapointed....not change too much in performance for my his4870...

already stated at review there no need to upgrade

thks 4 ze driver

Already download for my HD4850. Don't feel any difference in performance but there are some bugs fix = stable.

Can i download and upgrade for my ATI 9550 For this?

yes the ati 9550 support 9.3

its better you try some modded driver like Omega or DNA... those new drivers are not otimized to your VGA.

ya download now thanks for told update ^ ^

Nice, downloaded it and tested, and it seems to have gone some major performance boost than 9.2 CCC....Recommended for ATi users out there..
