    Finally have a line on a GeForce 3 for my G4 Cube. Figured I'd run Doom 3 on it, since Doom 3 was the "launch game" for the GeForce 3 - demoed on stage on a GeForce 3 on a G4 by Doom 3 programmer John Carmack himself, on a pre-10.0 copy of Mac OS X.

    Yet the minimum requirements are a G5, GeForce 5200FX, and 10.3.9+.

    I suppose the fact that it took three more years to finish after the MacWorld demo have something to do with it; but I had never looked at the system requirements on Mac before. I ran it on PC at the time it was new.

    Anyone know of any other "it should have run on system x, but actually requires system 3x to run" games/applications? (Other than Halo - the massive lag between its original "Mac only" announcement and its actual Mac release - with the stint on the Xbox in between - is obvious.)

    iirc, and I probably don't, it had something to do with the OpenGL improvements found in the late stages of panther.

    Unless someone knows this off the top of their head, it would take some hardcore googling to retrace this

    A GeForce FX is technically capable of what Microsoft calls PixelShader 2.0 (floating point shaders), while a GeForce 3 is not. I don't know what the OpenGl equivalent is.
