The first release candidate for X-Plane 11.51 is now available. (Release notes here.)
Thanks to the users who filed bugs (especially Bill), we now understand the issues with the HP Reverb G2, but the fix is not in 11.51r1. The fix needs more testing than will fit into this patch. If you have an HP Reverb G2 and haven’t filed a bug, please do, so we can find you to send you a possible test build. In the meantime, we won’t hold up 11.51 and the new Gateway airports; rather we can work on the G2 in parallel.
