--- Comment #20 from games4tux tioneobrasil@gmail.com --- I conducted tests using wine 1.7.44-gallium-nine on Playonlinux/Q4wine with native Direct3D enabled on my Radeon HD7770 using opensource driver radeonsi/gallium Black squares disappear, the game runs fine. I had problems with shadows and the replay. I came back to play the Shift 2 Unleashed!
