Hello all, I recently installed an official Sapphire HD 7950 in my MP4,1 -> 5,1. Since upgrading, none of the games from Feral Interactive work (Lego Harry Potter, Lego Star Wars, etc). I launch the app, get the options window (to select display, resolution, etc), but when I click the "Play" button, it just dies. Does anyone else that has same or similar hardware have this problem? Thanks!
