Hello. I would like to ask if it's possible to run FSX with sweetfx on a multiple monitor setup. I tried fullscreen but the frame rate drops to 1 fps. Also using windowed mode seems to solve the problem but when i undock a window it drops back to 1 frame. Is it possible to run Sweetfx on a multiple monitor setup or did i do something wrong?

Did you anabled the multi monitor option, through your Nvidia control panel first ? maybe that helps.... open your graphic card control and go to th 3D settings. Then anable your settings on the right side, specificaly for FSX.
