I checked, this is due to currently pSkipConstants parameter for
D3DXCreateEffectEx is ignored in effect framework. The constants listed in this
string should be ignored by effect framework, application sets it itself though
d3d calls directly. I checked that:
- there are meaningfull constants in this string passed by application;
- some constants are indeed set by SetPixelShaderConstantF directly by
application;
- if to proxy native D3DXCreateEffectEx nullifying pSkipConstants, native
framework renders the same black as Wine.

So I will remember this as todo for effect framework but I do not have a patch
for that right now.
