Hey NotSoHotNoob, thanks very much for trying Ubi-Milky's suggested fixes, and reporting back - that's very helpful!
Can you try the fixes from our
troubleshooting guide? In particular from that guide, please make sure you've updated your operating system, you've verified the game files, and you don't have any unnecessary background programs interfering with the game.
I notice one of the comments on the Reddit thread you'd linked suggests turning off AMD's sharpening tech. That seems a very wise troubleshooting step to me. Have you given that a go?
Here's AMD's guide on how to turn it off.
Does either of those steps seem to help at all? If not, I'll have some further troubleshooting steps for you
