on bug 65416
from Stefan Dösinger
Fwiw, I don't know if r600g is affected. The HW has enough varyings to run the unoptimized shaders, and the applications affected by this performance wise are CPU limited on my r600g system. Wine has some checks to prevent writing texture coordinates in the vertex shader when there is no input to generate them. Unfortunately 3DMark 2000 and Unreal Tournament 2004 use a strange vertex processing setup that breaks those checks(D3DTSS_TEXCOORDINDEX of all texture stages is 0, thus they're reading the first texture coordinate input, which does exist).
