ATI Drivers failing on startup with 10-2011 11-2011

Hi,

I started having this with the last two versions, all previous version of the UDK run fine. The symptom is that on loading the UDK editor the frontscreen would freeze and the asset browser would become corrupt. After maybe 30 seconds Windows 7 shows a message saying the AMD/ATI drivers failed.

I have now found a work around which is to make sure that in the CC you have ticked under SMOOTHVISION HD:anti-aliasing the following - Use application settings and Morphological filtering. I did just try the use application settings but it still seemed to fail.

I'm not sure what your problem could be, but I've had trouble with the AntiAliasing before. There is a setting in Unreal that enables Morph. Turning it on in Unreal might help. To change the setting, you must edit this file in a text editor: ...\UDKGame\Config\UDKEngine.ini. The video settings are near the bottom.

Other than that, I'm not sure what is going on. My Radeon 5770 works fine with AA turned off and Morph turned on. Maybe you'll find some settings in that file that can help.
