Runs great on my 5000 series AMD CPU and 3000 series Nvidia GPU, those came out 2 years ago now, and that's averaging about 50fps on a 4k monitor.
If that isn't optimized, idk what is. Yes, I had high end stuff from 2 years ago, but now it's solid middle range.
People are so damn entitled. There used to be a time in PC gaming where if you were more than a year out of date you'd have to scale it down to windows 640x480. If you want "ultra" settings you need an "ultra" PC, which means flipping out parts every few years. Otherwise be content with High settings at 1080p, a very valid option
