This has to be the wildest display of skill in CP77 that I've seen to date. Multiple times I was :O. This is how CDPR always intended the game to be played. Well done!
I have a 3080 with 32GB RAM and a Ryzen 7 5800. The video is 1080p but I play in 2K comfortably at 70 fps wich can go at about 50fps in crowded areas or Dogtown. And that is without ray tracing, with that on the game runs at 40fps and it can lag. It's better to just play in full HD if you want to use that.
