    ATI, FBO, glGenerateMipmaps

    This function doesn't work on ATI?
    I think the mipmaps are garbage, but level 0 is fine.
    Also, I guess there is some debug code in the drivers because in some situations, the driver calls interupt 3.

    an open source GLU replacement library. Much more modern than GLU.
    float matrix[16], inverse_matrix[16];
    glhLoadIdentityf2(matrix);
    glhTranslatef2(matrix, 0.0, 0.0, 5.0);
    glhRotateAboutXf2(matrix, angleInRadians);
    glhScalef2(matrix, 1.0, 1.0, -1.0);
    glhQuickInvertMatrixf2(matrix, inverse_matrix);
    glUniformMatrix4fv(uniformLocation1, 1, FALSE, matrix);
    glUniformMatrix4fv(uniformLocation2, 1, FALSE, inverse_matrix);

    Well, the FBO support in 5.6 are very incomplete. So this is expected unless you have some developer drivers with more than Alpha support...

    We have generate mipmaps working, but it's not in public drivers yet.

    I'm using public 5.6
    It's nice to hear about problems from other members.

    We have generate mipmaps working, but it's not in public drivers yet.
    Are there beta 5.7 drivers out?
