From the date on most threads it would appear that I am a little late to the FXAA show. What I have found is that I get the desired effects when running FSX in WINDOWED but as soon as I go to FULL SCREEN it's just back to looking like it always has. Not finding any helpful threads on this matter. Help appreciated.

You've been able to force FXAA on in the Nvidia driver using Nvidia Inspector for quite a while now. No need to use an external tool.

What about all the various changes that can be made using FXAA tool?

Wow, not much traction on this topic. OK.... what replaced FXAA tool?

i got the same problem.,but i use two monitors. Monitor 1 (primary) connected via hdmi-dvi adapter and monitor 2 LCD is connected via DVI.

FXAA only work in windowd mode on monitor 1.. if i change to fullscreen i lost bloom and HDR on monitor 1 :(

on Monitor 2 i can use FXAA in window mode AND fullscreen without any problems!
