When flying a transatlantic flight (CYYZ-EIDW) in the Boeing 747-400 the frame rate slowly drops. The cpu rate keeps increasing above the 0.03 level. After 4 hours of flying it is running around 0.043. By the time I reach the coast of Ireland it is up to 0.085 and the frame rate is around 12fps. Oddly enough, if I disable XLua 1.0.0R1 the cpu dives immediately down to 0.02 and the frame rate jumps to 60fps. Of course, when I disable Xlua I no longer have any data on the plane control panels. Any ideas?
