My GTX 970 on medium was fine. This whole thing is a little confusing to me, why would my slower card be faster?

Certain advanced graphics features are enabled or utilized if you have a graphics card that supports them. Unfortunately, the implementation of some of those features was poorly ported or implemented, so you end up with performance issues.

Ironically, because the older cards can't support those features, they don't have the performance issues related to the bad implementations.

I meant the Ryzen CPU (is there a GPU with that name?), should have been more specific.

My GPU is a GTX 1080 and it was unenjoyable to me with that CPU, now I have a 12600KF and it runs pretty well.

The OP article shows quite well how CPU bound this game is.
