[murphw_A350]

Intrigued by this - I have a pretty ropey computer by your standards (3.2GHz Xeon processor, 12gb RAM, 4gb 1050Ti) and haven't got 8FPS with the FFA320 apart from engine start (due to some daft DRM check.) Never going to be 50FPS, but even with some graphic-heavy freeware scenery I can still fly reasonably well other than at the "default" airports that are by Aerosoft i.e. Heathrow, Frankfurt.

The one thing I've found with X-Plane is download-and-go-fly it is not! I spend more time tweaking the sim than flying it!
