I was using fps limiter with a single display and it worked great. Now my setup has 2 displays for forward view in span mode. 2880x900. and a 3rd for instruments ect. sometimes I use a 4th old crt for gps and radio. with all this setup and run fsx via the limiter with frames set at 30 and unlimited (also tried 60 and unlimited) I dont get better then 15 inside fsx. Is this normal or is there another way?thxEric

You need to double the frame rate for each monitor, so for 30 fps across 2 monitors you need to set 60 in the limiter. With 3 monitors I think you would need to try 90 or possibly 120 in the limiter. You may find though that not using the external limiter at all is the better option when using 3 displays and just leave the internal limiter set at unlimited, this can even be the case with only 2 monitors on some systems.

thanks. I figured as much but never hurts to ask
