Thank you for testing this. I am a bit confused with "IsParameterUsed" stub
FIXME as my test patch here adds a real implementation for this function and
there should be no such FIXME in the code anymore. Could you please check if
the patch was fully applied and if you are using the version of Wine built with
the patch?
Regarding the problem you pointed, failure to create the texture looks like
enough reason to have anything rendered in black, and this issue is not related
to effects implementation. Still it would be great if you could attach an
output with WINEDEBUG=+d3dx (after checking the correctness of patch usage), I
would check if there are some evident non-implememented effect related features
used.
