--- Comment #37 from Nicholas Miell nmiell@gmail.com --- You could look for "# cgc version" near the beginning of the program source (almost certainly the second line), but that assumes the shaders weren't post-processed to strip out all the comments.

Alternately, you could just disable it entirely by default and include a driconf option.

The fact remains that the games work correctly on other OpenGL implementations and are ancient enough that they're no longer supported and will never be fixed.
