Hal, one last word about the problem, then I stop this discussion.
It is NOT a *visual* problem, then 60 Hz on a LCD is really golden.

The problem I am feeling at my PC is that with VSync ON and LOW VSync
rates the general performance of FlightGear is worser, even the
helicopter flightmodel *seems* not to be as smooth as with HIGHER VSync
rates in my graphiccard setup.
I explained this to myself that it *might* be that the FlightGear
program is loosing time and with that performance ALSO for other tasks
like scenery rendering, flightmodel etc. by waiting for the next frame
to display IF you have a fast PC-system AND your vertical sync rate is
rather LOW.

But  this is just a feeling I had when I started to solve the "without
VSync stuttering problem" and tested different setups of my graphic card.
A higher VSync rate would reduce these waiting cycles after my opinion.
But it would be very interesting to get an answer from a real FG
specialist  whether FG really is loosing  overall performance when
synchronized down to a low VSync rate with a high performance PC system.

Ok, this just said as I had the feeling there was a misunderstanding
what the problem is.
Regards
Georg
