Neu ist z.B. diese Passage im Abschnitt "Setting the Rendering Options":
ZitatX-Plane 11.50 adds the ability to run the sim with the modern rendering APIs Vulkan (for Windows & Linux) and Metal (for Mac). Check the box “Use Metal/Vulkan driver for faster rendering” then restart the simulator to use the new rendering engine. The sim should perform at higher frame rates and reduced stuttering with this turned on. Note that using this option may require graphics driver updates and that not all add-ons are compatible with Vulkan and Metal. If your add-on does not appear to work correctly, disable this check box and restart to return to OpenGL rendering.
