I am happy to learn that there is such progress with OLC Asia and that great care is devoted to its development (such as finding ways to solve the issue mentioned with mountain slopes)!
MSFS might have great graphics, but it still doesn't recreate the environment of flying an airliner (including GSX, AI traffic, ATC, some high-fidelity airplanes, precision of weather with ASP3D, and so on). Can't wait to be able to fly from Europe to Asia using the new OLC.
