What does “4k graphics” even mean? Did you just install 4k textures for everything or what? Either way, you can get modded Skyrim to look very beautiful, without being insanely demanding. I guess it depends on your resolution, but a 4070 should be able to manage it just fine, so I’m not sure what you did.
One of my favourite games to play with friends, especially if you get into character and drink some rum lol. I definitely play it mainly for the PVE, which I find relaxing.
