OpenGL 2... GLSL 1.2? Not sure about that one. It's at least 1.2.
...and non-power-of-two textures is also required.
Those are all deal breakers.
The Dell XPS I had supported 1.2 max. So yea, 1.2 is the GLSL Minimum for Mythruna. And even then, Bump-mapping doesn't work. (Lights don't work with the bump-mapping.)
