I am having trouble. When i hit alt semi colon, it goes to a blacked out stereo view but just a thin sliver of the horizon is rendered, just all the land and sky above me is blacked out. I looks like a negative (see attached). Do you happen to know what it might be? I have a gtx 680 with an up to date driver running on a 1920x1200 monitor, and all programs that you said messes with graphics closed. Works great when not in stereo
