I have used specs and normals in source before, just on a props for a quick test (without looking at the framerate back then). But now I wanna do more with it in source, and now I'm starting to do some tests before starting the real work.
I did some tests without HDR and no specs, that seemed to work a lot better indeed, I'll do some more tests tomorrow, but it looks like I'll need to work without specs/hdr...
anyway, thanks for clearing it up R_yell
