KT400 Vista and Radeon 9600PRO 256 MB AGP

[eramic]

I have installed Vista 32bit, I've got everything to work fine except HW acceleration on my Radeon 9600. Aero is disabled and everything related to graphic is slow.
The Windows Vista score shows 1.0 for both the video tests! An ATI Radeon 9600 should be much faster. To try and fix the problem I have tried installing the current ATI Beta drvs, oficial drvs these install fine but still no acceleration. I've tried removing these and using the windows drivers and reinstalling again. Still no HW acceleration.
I've checked 'dxdiag' and acceleration is disabled for AGP and Direct3D is NOT AVAILABLE
I've done a lot of online searches and can't come up with anything. I know that Radeon 9600 128bit 256 MB AGP is not state of the ART but I am preatty sure that it is strong enough to run Vista Aero interface without problems.Even NV 5200 (AGP) 128 MB wich is much worse card perfom better in Vista on same computer. It looks like it is some kind of strange issue between Via AGP and Catalyst drivers. I've also run the Windows update and none of the updates made a difference.
PC SETUP
Windows VISTA 32bit Ultimate Edition
asus a7v8x Motherboard (VIA KT400) (latest BIOS)
Athlon XP3000
1 GB DDR 400
Radeon 9600 Pro 256mb
550W Branded PSU
(With XP everything was fine)
(Vista is not upgrade I performed clean setup)
(Tryed everything in bios FW: ON OFF, AGP performace control: ON OFF, Aperture Size from: 128-1 GB, diferent memory modules etc....

Any recommendations?

try version 7.7 or 7.8, 7.9 and 7.10 are screwed up.

eramic,

Do you have the Vista compatible chipset drivers for your Asus motherboard installed? I don't know whether the Vista installation DVD contains those chipset drivers. Just an idea.

Also problem MSI KT400 + Radeon X1650,

Why VIA doesn't make drivers that support also 3D in vista with this chipset
