Doesn't work for me((
Ok, I had all the ticks off in the graphic settings. So not just Vsync, but unticked every box. Set the MSAA to four and it'll change the graphics box to a line rather than low etc. Took a little bit of load time but then went through, changed the settings back to normal to explore, then off again once I exited. I'm a little ways in now and haven't had the problem occur again.
