i want to ask can i do little bit shading language with my old intel's
Mobile 915GM/GMS/910GML Express Graphics Controller
and
vendor 1.3Mesa-7.0.3?

is there software mode for GLSL to do with non-supporting device?

i asked these question cause Maniadrive(all knows game)
worked with shading language on my chipset(slow but i feel i am lucky ) and have difference in on/off shaders.

Yea you can use shaders on old intel chips.

But not GLSL. What you will need to use is 'fragment programs', not 'fragment shaders'.

A fragment program is a small piece of assembly code that allows you modify your vertices and fragments.

For more info refer to:

I hope this helps. :)
