The problem is that on older cards the game seems to push the card to its shader limits. (It tries to use all the available 'registers' / 'constants') Wine needs a few of those to handle some stuff like fog, srgb and other things. For this reason there aren't enough uniforms left for the game. The latest cards have enough shader capabilities.
