Re: [Flightgear-users] Strange rendering and performance problems with FlightGear 2.4 for MacOS

[Jack M. <jhm...@ya...>]

Thanks, Curt,

I tried your recommendation.  The flashing airplane skin went away.  The perceived frame rate improved from less then one frame per second to about three frames per second to a frame rate of better than three frames per second.  The performance is still better using v 2.0.0.r284.  The scenery looks better with that version, too.

When I opened fg at KSFO with the default Cessna 172, the skin of the aircraft was flashing and had weird patterns that kept changing.  Redrawing of the window became very sluggish, about one frame every 2 seconds.
