Since 8.1.3 I can get the game to run at any resolution without a lockup. However, the only things that don't make this game playable are the black flickering textures (and technically movies). The black flicker only occurs with "outside" polygons are being painted. I have tried everything I can think of, but no improvement, though it is better then previous version. Hardware is a Mac Pro w/ OS X 10.6.2, ATI 4870.
