I dived into visualsettings.dat and tinkered with a few things. Notably I increased rain particles (about +4k) and the minimum size for ripple effect as well as increased the range that DoF takes effect, reduced it's low valye to 0.05 and medium to 0.40 to help compensate for the lack of fog. There is no tampering with Tonemap or anything else too specific, making this mod very SweetFX / ReShade friendly
I edited all 4 timecycle files. I focused on a few things. Extending farclip, disabling fog, noise & chromatic aberration for all scenes & locations in the game
I nullified all fog_density, postfx_noise & "chrom" values in most weather files ("Fog" and various "Snow" types are untouched)
Open the "common" folder within, then open the /data/ folder
Scroll down and click once on "visualsettings.dat", open a menu over the file and select REPLACE
Browse to my download, which you should have (by now) extracted the files to somewhere on your desktop; select my visualsettings.dat file, and replace the one in OpenIV
Continue these steps to replace the timecycle and weather files. timecycle_mods_2 is not in the update.rpf file, just add it into the same folder as the one's you are replacing! Anything in update.rpf will override common.rpf
Navigate to OpenIV's File tab, select REBUILD; When finished click "Okay!"
Start Game and enjoy!
As I may be making updates, I only ask of you to credit me (ubtri) with a link to this page (or to http://www.gtaforums.com/topic/793567-vrel-improved-visualsettings-fog-chroma-removal ), but please feel free to distribute these files or even branch your work off of mine!
