Multipass? Does that mean running two (or more) different shaders in two (or more) passes?
I guess this would require a pretty fast video card...

I really like this shader very much, of all the shaders I tried out so far (!) this one and your SuperSAL Shader are my personal favorites.

I wonder why all of them look better using high x and high y internal resolution, compared to high x and very high y?

Multipass is hard to do because it require one or more temp buffer(s).
For multipass, the sequence became:

pbuffer ---> temp buffer (first pass)

temp buffer ---> temp1 buffer (second pass)

....

tempx buffer ---> back buffer (last pass)

You can reuse the same buffer but you must consider
that you have a double (graph. card) memory usage.

It seems to me that all shaders are strictly linear programs.
If this is right, your options must be very limited and I understand why you think about multipass-shaders.

Is there a way to write more complex shaders, maybe with next generation video cards?
