Issue with dual monitor nVidia set-up (nView)

[jetlag 65]

I am starting to experiment with dual monitors using:

- GTX460

- Win 7

- FS9

- main display LCD at 1920x1080 (60Hz)

- secondary analog CRT at 1600x1200 (75Hz)

 

I start in 2D cockpit view, create a new front-left view, undock and drag the window to the CRT.  As soon as half the window is visible on the CRT, the frame rate drops from 30fps (locked) to exactly 1.0 fps and stays there.

I would expect a frame rate hit from having two 3D views to draw but this looks like a setting issue. I have played with the screen resolutions, with no effect.  I have no problem if I move instrument panels. 

 

I have searched the forums but not found anything like this.

 

Thanks for your help.

It's been a long time since i worked with multi mons- but if I recall, each view must be completely within its own monitor- if even a tiny wafer of a view remains outside that monitor, you get a catastrophic frame rate drop. Be sure to size the image to fit within its monitor.

Thanks, January.

The slideshow goes on when the window is fully within the second monitor.   Same happens with tower view, topdown view,...

 

What really puzzles me is the exact and steady 1.0 frame rate.   Another possibly useful observation: having released the brakes I notice that the two displays refresh in alternance: 1 2 1 2

Can you try using the same resolution for both monitors? Perhaps a conflict there..

I did try that.  No difference.
