Ok, the pack is ready and the site is mostly updated. I haven't added it to the main pages yet, but you can get straight there through here :

At the moment, the only demo I have available is one I made in another tool using the same shaders. It shouldn't be much faster or slower in another language or tool because shaders do most of the work themselves. However, I do need a demo running in 3DGameStudio and that's the next thing on my list. Hopefully I'll have a simple parallax mapping demo on a sphere added within the next day or two.

I can't say how a 5700LE card will fare, but it is really a glorified 5200, with virtually identical performance. It claims to be shader model 2.0 compliant though, so it should at least run all the shaders ok.
