Irrlicht Engine

When I run the shader example with dx8 everything is fine. When I run with OGL I get a warning that pixel shaders are disabled because of missing driver/hardware support. I have a Radeon 8500. Does anyone know whether
1) the fault is in my video drivers

2) a radeon 8500 can't run pixel shaders at all. (don't know what's with dx saying it can though, and anyway I hope this is not the case)

3) the problemis in the irrlicht OGL driver

I've just noticed the same problem here with my radeon 9000. It looks like the OGL port will give everyone a good headache

well i certainly ain't a gl guru but an easy way to find what your card supports is the nehe lesson24 ...im sure there r other programs that return all the GL extensions your card supports but this one is pretty easy.

what you are looking for is

GL_ARB_VERTEX_PROGRAM //vertex
GL_ARB_FRAGMENT_PROGRAM //pixel

when those 8500 first came out they didn't support GL_ARB_FRAGMENT_PROGRAM ext (haha i don't even know if that extension was around than?) ....but with the latest drivers they may do????

you may notice your card supports the older GL_ATI_fragment_shader, so i guess irrlicht could always be modded to use this if found.

here is a great little app to find your opengl extensions
