Does your system meet the minimum system requirements? Serious X-Plane flight simmers have a system equal to or higher specifications than the recommended system requirements. The details can be found at https://www.x-plane.com/kb/x-plane-11-system-requirements/
Also, is your system a 32 bit machine or 64 bit? Have a look at the following link found at https://www.x-plane.com/kb/running-memory/
