Here are my tweaks of TWPOSTPROCESS.FX shader, that gives more visible* WOP-style vignetting effect, and slight color correction, the screenshot hasn't been modified in any way:
here's the file, drop the Twpostprocess.fx into your modfolder/Flight/
also I included other variants in their respective folders, various "strenghts" (or more correctly fading levels) of vignette effect, also with overexposured curves variant, aswell as another modification that gives somewhat "old film" postprocess as seen here:
This post process effect is available only in Dx10 mode, with effects set to unlimited in options menu. Feel free to experiment.
*the very, very slight screen vignetting is present in SF2 series, I noticed this fact only after TK brought that to my attention
Have fun
