I am trying to run a game (Magic the Gathering Online) under Parallels. Without the experimental shaders option checked, the game crashes in the load process with an error about writing protected memory from ~Direct3Dx.Flush() or something. When the shaders option is enabled, the game runs, but the window goes black as soon as it is drawn to. When screen elements are updated, they appear briefly and then go black either immediately or after a few seconds. Resizing the window causes everything to appear, and then return to black. So it almost works, but not quite... any help?
