Hi there, using XP11, pb9
HTC Vive
Windows 10 machine
Aircraft was Virtavia's C17
this was after somewhat recovering from a "black screen" event... as has been noted on XP forums sometimes the monitor XP display and the Vive will go black; the sim is still running, sounds are normal, the framerate indicator is framerating, the aircraft is flying, all is normal except for the black screen. what I have found is that changing the antialiasing setting within xplane will reset the graphics, i.e. get rid of the black screen, and let me continue the flight. so when I get the black screen, I go into graphics settings, change the antialiasing slider, hit "done" and I am back in the virtual cockpit.
In this particular instance the graphics came back but were "offset" as if the two vive lenses were pointed at different places. a few seconds later the whole thing crashed and the error message attached was generated.
