X-Plane 11.50 (Vulkan and Metal) Beta Released

Laminar Research has today released a long-awaited update for the X-Plane 11 simulator. X-Plane 11.50 is currently in a public beta phase. This update is adding the option to enable rendering via Vulkan and Metal. To enable the new modern rendering via Vulkan and Metal, you need to check the option in the graphics settings screen and restarting X-Plane.

X-Plane 11.50 is a major update that completely rewrites the rendering engine to use modern rendering APIs: Vulkan (on Windows and Linux systems) and Metal (on Mac).

Please note that it’s still in the beta phase, so not all addons will work with the new rendering engine. Few of them being ToLiss A319 & A321, FlightFactor A320, xEnviro, XPRealistic Pro or xPilot, for example. I’ve put the complete list of the addons below.

known bugs

There are still few known bugs such as dark contrails instead of white or CTD when regenerating icons for current aircraft. Please keep in mind, that the simulator’s first load will be slow. This is due lot shaders/pipelines compiling for the first time.
