maybe it was because of the earlier opengl patch 'Store GL context in
TEB'. But I didn't notice such an increase then.. only from ~20 -> ~30fps

good, at least something :)
Something else.. now I know why there is this VisualID mismatch. Someone
didn't read the GLX spec. in opengl32/wgl.c:describeDrawable() you call
glXQueryDrawable() with GLX_VISUAL_ID, but that's not allowed ! only
GLX_FBCONFIG_ID and three others, according to the GLX 1.3/1.4 spec .
According to the spec, you can get the GLXFBConfig from a GLXDrawable
using glXQueryDrawable() and then the Visual from the GLXFBConfig using
glXGetFBConfigAttrib(). .. I'll send a patch.
