Hello all,

As you can see, I have removed as much overhead and only have the most
minimal graphics. The scenery settings are all set to the lowest,
weather is tuned down as well. I have noticed that when I just use the
Primary Display (Display 2 with the NVidea 256MB card) with no other
monitors activated within MSFS then I can get upto 75 frames per
second. (Using Shift Z twice will show you your frame rates withing
MSFS) Once I enable another monitor by dragging a instrument panel to
it or another display optiopn such as the GPS, etc, then the fram rate
drops significantly, now 20-30 FPS. I enable another monitor and drag
an item to it, the frame rate drops again, now 12-18 FBS. When I enable
the last monitor, I am now getting 3.5-8 FPS. Very slow and choppy.

I went out to the NVidea support site and there is no drivers (that I
can see) that I can download for this card. I have not updated the
drivers to the other 2 cards (yet). However, I am certain that that
will not make to much of an improvement. I also went into the NVidea
display properties for that card and did not see anything that stood
out.

My question are these:

1) Why would the frame rate drop on the primary display when I enable
other monitors?
2) Shouln't each monitor frame buffer (Video card) manage it's own
resources
3) Is there a work around for this?
4) I know that other people are running multiple display's, are they
running into the same problem?
5) What is the best practice within the hardware settings in MSFS?

Any help would be greatly appreciated.

Thanks,

Greg

Greg,
I run three monitors and have no problems. Your setup sounds quite complex.
I think a much better newsgroup to ask this question would be

alt.games.microsoft.flight-sim

It is much more active than this one, and there are some extremely helpful
and knowledgeable people there.

Good Luck
