I am running FSX on a 24" LCD but recently connected an additional 15" LCD to display GPS, FMC etc. Both monitors are connected to the same graphics card and I run FSX in full screen mode. Everything is setup correctly within the windows environment and I am able to move the FMC to the smaller monitor when running FSX. The problem I am having is with performance (FPS) which has dropped by a third within FSX when the second monitor is connected, whether or not I move any instruments onto it or not. Is this just the way it is or is there something I am missing. The OS is Vista 64 and I am using FPS Limiter. As per other forum posts I set FPS limiter to 60, rather than 30 when I was using just 1 monitor. My system specs are: Core i7 965 EE @ 4Ghz, 6Gb RAM and Nvidia GTX 280. Terry

Same issue here. Would love to know if there is a fix.

Hi Terry - FPS Limiter is the issue. It's not the number of monitors but the number of windows open on those monitors. For example - set FPS Limiter to 60 and run FSX with both monitors open but nothing on #2. You should see the framerate close to 60. Now open the GPS window and move it to #2 - you should see the frames drop to about 30. Now open the Comm stack and move it to #2 - frames will drop to 15. IIRC this will also happen on one monitor if you open 3 windows.HTH,Vic

Well, I tried it with the second monitor deactivated in the nVidia control panel and couldn't see more that 1 FPS difference if any. I've limited my display to 20 FPS whether with one or two monitors active.

I have an older system with a Radeon X1950XT card and see absolutely no difference if disable the second monitor or not. I think it's mainly what all you have open as suggested above. I usually use my second monitor to run STB fullscreen and run FSX on my main LCD fullscreen (windowed mode).

Hi Vic, even if I don't have anything dispayed on or moved across to the second monitor the FPS still drops dramatically. It drops by a third whether I have zero or 3 additional screens moved across to the second monitor. I'm beginning to think it may be a driver issue. I'm currently on the 185 WHQL's but will try the latest ones.Terry
