Unfortunately that didn’t fix it. Also weird - I’m at leg 17 now and all legs are ok - except that 7th leg where the fps drops to 9-15fps as soon as I press the ‘Ready’ button.
I wonder if this can be a specific issue with certain legs in Bush trips. But then I don’t get it that i don’t have the issue when starting from the same airfield, same conditions, without loading the bush flight. A bush flight is only a collection of instructions and waypoints right? What on Earth could loading a certain leg cause such a massive cpu/fps hit :-/
