--- Comment #14 from swswine@gmail.com --- I see that there is a support for constant buffers but it requires ARB_UNIFORM_BUFFER object extension that your GL does not have. So it would probably easier to test the game on the newer GL. Still constant buffers AFAIK are D3D10 or D3D11 feature and the use of d3d10 or 11 in the game or wine prefix installation (if this is indeed the case) should be sorted out anyway.
