You can use any recent preset, just make sure high precision mode is enabled, and make sure there is an effect.txt file with the noise effect included with the ENB. Also make sure HDR is set to HIGH in the game settings of course or ENB won't work.
I set the noise effect to these so that it is very subtle:
Grain Motion = 1.0000
Grain Saturation = 1.000
Grain Intensity 0.001
you can adjust the effect by bringing up the in game ENB editor, and opening up the effect.txt tab in the shader parameters window. I also turned off Edge Smoothing and LumaSharpen in the effect.txt settings.
I have no ENB effects enabled at all so it's not really worth sharing lol
Is there an FPS drop when using this?
I recently used wickfut's AA + AO only preset and it dropped my frames by about 25 fps. Gotta have that smooth 120+ fps at all times.
If you don't use any ENB effects at all, the FPS impact will be very small, if any at all. Just uncheck all the extra stuff like AO, DoF, BLOOM, etc, and then CHECK UseOriginalPostProcessing. It should then look like vanilla DDDA.
