I've actually got that game myself here.
So I did the bisect and the winner is:
ce7a045feeef8cad155f1c9aa07f166e146e3d00 is the first bad commit
commit ce7a045feeef8cad155f1c9aa07f166e146e3d00

    r600g: use ieee variants of multiplication instructions

    This matches the behavior of most other drivers, including nouveau,
    radeonsi, and i965.

Looks like some numerical issue then, albeit I don't know if the game is at
fault here.
