I just want to run flightgear without scenery for maximum framerates and testing aircrafts without lags.
Is this possible without hacking the source code?

Not giving you any attitude at all - we've been debating if you were wasting our time or not

Anyway. By setting all to false / 0 at runtime with the UFO I did not get more than about 40 fps, and after running for 10 minutes i was down to 25 fps.
Which probably "prove" that the tendency to get low framerates is not all about only the scenery or aircraft issues. I was expecting atleast over 100 fps with no 3d things rendered.
I must say that I am on optimus laptop, but that should not be the problem as I see others report simular decrease in fps after running it for a while.

Hooray wrote in Sat Jul 05, 2014 9:14 pm:Nope, your conclusion is not correct: scenery tiles will be loaded regardless of those draw masks - which is why the minimal startup profile uses a location that is guaranteed not to load any scenery.
