Not carping Z, just FYI...I use the iPad 1, 64 g....after latest update can report similar sluggish plane performance. Speed seems about the same, but turn ratio, rate of climb are significantly diminished. Still getting weird bomb message at odd times. Landing is now a very tricky maneuver, and taxiing...esp. inside the boat is near impossible. Worst effect seems to be impact of new smoke/fire graphics... result seems like perpetual lag. Only way I seem to avoid it is to try to keep those graphics off my screen...fly away or otherwise around it to keep it out of view. Result is usually severally well placed rounds into my plane with the ensuing carnage. Will wait for the next update and let you know what happens.
