All have been done, it's vanilla game, I don't really overclock, don't use peripheries, drivers are up to date, I've done all disable fullscreen and the like. Heck, I have the game running in potato settings, all graphics settings set to their lowest and least taxing setting. Literally the only time this has become an issue is just recently, and seems I'm not the only one suffering these problems, and that it's been nabbing more and more people since the launch of ShB.
