Glad to hear that you managed to solve it. Thank you for reporting back with detailed information, I'm sure that will be of help if anyone else is having the same issue.
It's interesting to hear that you are getting a segfault when exiting the program. I use Unity's Application.Quit() command, which should stop the program properly. So I don't think it's something that you need to worry about, although it would of course be preferable if it didn't happen.
I'm glad that you are happy with the sim. Yes, one of my goals when starting the development was to try to make it as lightweight as possible, as I know a lot of people don't have dedicated gaming rigs. (Also, FPV Freerider classic and FPV Freerider Recharged is available for Android, which makes it necessary to keep the hardware requirements as low as possible).
