So: first day some quick setup if http://www.gamersyde.com/thqstream_the_witcher_3_sweetfx_color_correction-w2lhE7zSLYYyrBCs_en.html <- this guy delivers, and I'll tweak my own setup more after I have satisfied my need to get into that amazing world
That's my vid.
The profile has been tweaked since, changed to a bit (minimal) more redish mood and the contrast on vegetation has improved.
Apparently CDPR has changed the yellow tint for the final PC release, so I'll have to test if the profile still looks good when the game comes out.
You can see a demonstration below (open full-screen) from an album I found yesterday with high quality pics, if the pics from this album are from the final version, then I'd say the profile still does its job.
If anyone's curious as to how a current screenshot would look with the preset, send me the link and I'll upload it.
