I'm using F:\DCS World\bin\dcs.exe as the selected executable. (I don't have Steam).
I have F:\DCS World\bin\Launcher.exe selected in RP's Launcher Tab
I have SweetFX located here:
F:\SweetFX 2.0 Alpha
This location is set in RP's main settings. Here you will see a category called SweetFX Settings, tick the "Enable SweetFX Integration" box and select the rootlocation of SweetFX (F:\SweetFX 2.0 Alpha in my case)
Back to the SweetFX tab, I have enabled/checked 4 settings only:
1.LumaSharpen (sharp strength 0.75, sharp clamp 0.035, pattern 2, offset bias 1.00 and show pattern 0)
2.Lift Gamma Gain (all 1.000 except for RGB_Lift which is set at float3(1.000,0.935,1.000) This seems to make a better contrast to the green/brown landscape, not so washed out, and targets stand out a little bit more.
3.Curves (Curves contrast 0.20, Curves formula 2)
4.Dither is checked
With these four enabled it looks good in my eyes. Experiment with it to your liking
Hope this helps.
Regards,
Chris
