I did play around with Sweet FX, here's the file for anyone interested:
I've re-packed my configured version of ReShade with SweetFX. This version is for the 64 bit version of BMS. Just extract the contents of the ZIP file to your ...\Falcon BMS 4.33\Bin\x64 folder.
To uninstall simply remove the relevant files and the SweetFX folder. There's one caveat: while you can turn on/off SweetFX in the game menus the key (scroll lock) doesn't seem to work in the 3d world so you can't switch it off/on while flying.
It you encounter problems, turn off multi-sampling the falcon grafics options.
