Vista 32 bit and Ati x850xt

[Offler]

since my machine was fully able to run this windows i tried it.

Later i start to examining its drivers and possibilities...

I found very terrible things about newer Catalyst drivers. Catalyst 7.x and later are causing trouble with Shaders and they are lowering performance and many games even cant start (not a compatibility problem).

Catalysts 8.x and later do same bug, but the Aero is functional.

Catalysts 6.x work correctly, but aero is not functional.

The most mysterious for me is the WDDM driver which was delivered with Vista. It works with aero, some games work with it, BUT it does not contain files necessary to run OpenGL based apps (atiglxx.dll and other ati opengl interfaces).

is there a way how to import opengl files into WDDM driver by Microsoft? change of hardware is not possible...
