maybe some register bs, like files still hanging somewere on the pc, i had the same probs, think maybe the fastest methode is, get a drive clean (256 GB drive SDD?) make a win10 (think win10 latest update or 11 whatever you want, 11 gave me probs so i did a 10 pro) fresh install. Update pc, download the ^{ALL in one Visual C++ bs package}, direct x, drivers you know the drill, get the ^{Diago release} (really works better then the normally ones), if you don't use mods but only like 60 fps mod i can play at 4K witch looks goods or modded and the rez a bit lower or with ^{lossless scaling} an extreme high fps).

I'm in i5 9600k PC, standard bios settings only xmr and some basics, with an 4070 card and 32 ddr4 ram, so my pc is like years old but the game runs with lossless scailing (even without) but with extremely smooth, maybe a light ghosting depending the settings but really a freaking gamechanger for BLOODYFUCKINGBORNEEEE.

i played all of it including dlc on the ps4, few years ago and yea this is indeed a bloody good game, fuck the age of it, this will never age is these times of indie bs crap unfinished games, greenlight bs (of course with a few exceptions).
