Perhaps its also card specific. Chris could you enable pixelShaders (SET pixelShaders "1") and try out the patch from the parent mail? > On Tue, May 6, 2008 at 12:39 PM, Markus Amsler <[EMAIL PROTECTED]> wrote: > >> With the attached patch I get in wow with enabled pixel shaders with my >> rv370 10-15% better frame rates.

There's still time to save $100.
