Yup
The parallax one is gorgous to look at, but pounds my GF FX5600s frame rate (something like 40 - 50fps) at the scale shown, though Noel Cowers spangly XT800 got about 600fps I think
Not all shaders are slow, the toon one is quite fast, alone and full screen I get abotu 1100 fps, the lattice (cage looking) one is slow. Fill rate is a big factor on performance, the more the geometry fills the screen, the slower it gets.
Shaders can be loaded & used with about 4 function calls in my (bunch of functions & types I call an 'engine' :) ), and you can turn them on/off per entity surface.
I've currently got a few problems that aint been answered yet though :S Maybe if MArk reads this thread he'll have an idea what's going on here?
