There is the OIT example here called
Order Independent Transparency 2
http://developer.download.nvidia.com/SDK/9.5/Samples/3dgraphics_samples.html
and if you look at the pic, the right side is the “bad” version and the right side is the “good” version.
If I run it on my Gf8, the “good” one doesn’t look quite transparent. I can’t see the balls behind the teapot.
It seems as if depth peeling is not working.
