    They are for me (options are greyed out, except vertex shaders)...and I just want to check if that's normal, and if anyone knows a way to enable them (suppose not).

    nope, your graphics card cant do those effects in hardware so you cannot enable them.

    Well, technically it can, since it supports PS1.4. The PC version supports pixel shaders on GeForce3/4, which only have PS1.3.
    So I guess there's another reason that it's disabled...

    There is. The only available pixel shading extension to use on OS X for that GPU is ATI_text_fragment, a format which WoW does not support. WoW can only use ARB_fragment_program, which the R9200 can't do.

    Ah...I was thinking that it had to be due to the OpenGL implementation.
    Those bastards...guess I'll have to sell my iBook and buy a Dell :rolleyes:
