All the aircraft in xplane 11 uses fuel at an extraordinary rate! Default 172 is something like 6 min for full fuel. Clocks in the aircraft run at normal speed.
I am beginning to think it's some sort of copy protection and that somehow my key registration is not working correctly. I do not use XP much, about once a week and everytime I start it it asks to verify my key and it says it is ok.
Running the latest version. How do I fix this?!?
