You know, there might be some merit to that, Beachdog.  I usually get good frames (20-30), but it so happened I had installed UTX and was coming in at night, when their lighting effects take a toll on FPS.  That was also the first flight with REX, which obviously dragged me down some, too.  I am sure my frame rates were significantly lower than usual, even though I didn't notice stuttering.

Life is full of compromises.  If I need to save REX for a different airplane, that's not going to run my life.  And there are downsides to flying the 757 at night, anyway.

As an aside, I was watching my Air Tours 757 cockpit video.  I'm not sure the training captain who was flying knew what he was doing after reading all the posts on this forum lol  But man, was everything familiar!  CS did a good job on this one in so many ways.

I hope the folks that are rockin' are getting some relief.
