Gonna give it a shot.
I'm having the same artifacting happen in RDR2 where the game is basicly unplayable unless i use TAA, but that just blurs the textures to all hell and causes massive ghosting, Hell Let Loose (The one in the image), Fallout 4 if i put shaders on, Call of Duty: Modern Warfare, All of the Newer Tomb Raider games and in the newest Wolfenstein.
Also i know for a fact one of my friends has the same weird shadow texture problem in Call of duty: Modern Warfare
Thanks for the help for now though, i'll try tinker with it some more and if it don't work, then i'll probably just end up getting a new rig whenever Ryzen 5000 get release instead.
