Colimata Developers, who are responsible for their rendition of Concorde for X-Plane 11, has previewed an upcoming update for this rendition, which will provide us with various fixes, Vulkan/Metal compatibility and much more.
These previews were shared via the X-Plane.org forums by developer Emma Bentley. The previews are showing off the cockpit, new INS and the exterior of the aircraft as well. It has been said that they want to push this update once X-Plane 11.50 leaves beta and will be out as a stable version of X-Plane.
