X-Plane performance problems range from persistently low frame rates to periodic stutters, long scenery scans and aircraft-specific slowdowns. This hub examines CPU and GPU bottlenecks, graphics settings, plug-ins, custom scenery, shader or preference issues, memory pressure and the different constraints encountered on Mac and Windows PCs.
It also explains what to do when X-Plane 12 appears stuck on “Reading new scenery files”, and why a turboprop showing high RPM or delayed response may involve aircraft configuration or simulation behaviour rather than raw frame rate alone. The Fly Away team tests fixes where practical, with an emphasis on changing one variable at a time and preserving backups before deleting caches or preferences.
