Big FPS loss when using a 2nd screen for instruments

[Lucas777 0]

Hi friends, as title says I'm having problems trying to use a 2nd screen for Instruments
 

Always I move a new undocked window to the 2nd monitor it eats a lot of FPS.

 

IE:

 

No windows: 30 FPS fixed

1 window: 20 FPS

2 windows: 10-12

3 windows: <10

 

I tried the NGX undocking ND/PFD/EICAS, tried also the Aerosoft A320 making views for those gauges, even with the default 737-800, results are pretty much the same.

My system

i5 2500K @ 4.5GHz
8GB RAM
GTX 760 2GB
W7 Professional
FSX Acceleration windowed mode

Any idea about what can I try?

 

Thanks in advance.

Some additional info...

 

I'm using FPS unlimited with no external limiter

 

Setting ForceFullScreenVSync to 0 improved FPS a bit but still bad.

 

Vsync at nvidia inspector is set to "force off".

 

Not sure what else I can try.

Its a Windows loss of focus thing, Accelerates the main display. Running in fullscreen will resolve the issue. Other than that, I never found a solution. P3DV2 resolved the second monitor undockiung frames issue somehow.

Thank you rend, I realized that couple minutes ago.

I was told undocked windows wouldn't work with full screen but they do.

Thanks!

I am planning on using a second networked computer for the instruments...I assume this would help.

You will also face a lot of different problems following that path.

I think the only downside with the multi-monitor setup is the performance loss, if you can keep it within the acceptable limits you'll be just fine.

 

I need to make a lot more testing but it seems running the sim in full screen mode fixed it for me. (crossfingers)

What are the problems that I would expect?

According what I have investigated...

 

- You need at least one, or more machines.

- You need a software that capture the part of the screen you want in the secondary monitors, tried some demos a freewares, nothing worked properly

- If your network bandwidth isn't good enough you will suffer FPS lag.

- You are still adding extra load in the main box, since it needs to generate the images that are transmitted over the network, unless you use a program like project magenta which transmit only raw data, they use to cost a lot of money and doesn't work with paywares like the NGX.
