Hi again people, problem solved ! :D I've just recompiled the latest cvs of plib, simgear and FlightGear, turned on the threads flags, and now I have a FG running up to 60 fps (i have forced the synchro with the vertical refresh). Cuold somebody explain me the way to tune FG options to get the best perfo ? visibility, threads, dynamic terrain loading ...
