g.exogen, just add
#else
gl_FragColor = vec4(0.0);
before #endif in preZ.shd and it will work on GeForce FX

Nintendog, yes, dynamic branching is supposed to speed things up, and it does speed up things a good deal on X1800 (about 50% in single pass and 140% in multipass). Nvidia's dynamic branching implemention needs a lot better coherency to see a performance increase. This demo should have a pretty good coherency though, but apparently not good enough to see a performance increase on Nvidia.

Darrenc182, the demo doesn't enable or disable Vsync, so whatever you have as default in your driver control panel is what's going to be used.

Could not compile shader on my GeForce FX 5700

Humus I'm not sure if vsync is enabled or disabled because there is no option to enable it or disable it. If the the default is enabled or disabled then that is what it is.

At 1024x768, with no AA.
6800 ultra 256.
Runs around 10 fps slower with dynamic branching enabled.
Isn't enabling dynamic branching supposed to increase the framerate?

You mean it's locked at 60fps? Do you have Vsync enabled?

The demo works fine on my 6800 with OpenGL 2.0 and I think the latest nvidia drivers. I get a speed increase when dynamic branching and single pass rendering is enabled, but the demo runs at 60 fps most of the time on my machine without a either enabled.
