When you find one you like, download it, go to your SF2 folder and click around in the directories until you find SweetFX_settings.txt, drag the one you download in, let windows overwrite and replace the standard one. To actually use SF2 you have to find a setting, Google 'DCS Sweetfx settings' click an ED forum link and there will be several posts with 'SweetFX_settings.txt' files linked. I think they've got some screenshots up for your perusal.

Found a whole list of them for Skyrim here just from a Google search. From what I know most/all of the SweetFX presets are fairly performance-friendly (compared to ENBs). I forget if you have to remove it so just be sure to keep it on your desktop in case you need to drag it back in. Copying and pasting the one you want to the main directory should do the trick. After you do this try starting up, if it doesn't work then you can go back and remove the Reshade32.dll (KEEP THE RS64 RENSMED TO DXGI) from the bin folder. You need to go into the SF2 folder and rename Reshade64.dll to dxgi, this tells the game to render using DX11 with DCS just recently gained support for. It started normally but the graphics havent changed at all. To use SweetFX integration, you must first enable it at RadeonPro Settings and inform to RadeonPro where SweetFX files have been unpacked. I have installed the folder within zip folder to my dcs through jsmge but it had no effect on my game. SweetFX gives you more control over image quality by applying lots of post-processing effects, allowing users to personalize the visual of games to fit their own taste.
