Thank you Roger for all your posts regarding DX10. I have given up on it long ago and after I fine tuned my setup for DX9 using Nick Needam's guide. There are two things keeping me from trying it out again. One is the ENB mod and the other is the FSWC. ENB might have other alternatives but I will certainly wait for the FSWC+ that supports DX10 to come up as I just love those water themes.
I will bookmark these threads and the avsim ones for that time.
Edit: Looking at Paul Wheeler's forum, it seems that FSWC will not work with the shader 3 hack, so I guess there is no reason to wait. I might give it a try and if I don't like it , I can just get back to DX9.
