I don't know...I don't use the windowed mode at all. All I know is that if I set the DSR to 2.5 or 3x native, and I set FSX to that resolution- I have lower FPS...But if I then reduce the resolution in FSX to my monitors native resolution, I have very smooth, consistent FPS and performance... much better than if I don't use DSR at all and run
native res. throughout
