Runs fine for me. 5600X, RTX 3080 @ 1440p high-ultra settings native.
Same here except I use a 6600 xt, which isn’t anywhere near as good as your GPU. I’m running medium settings at 4k and it’s fine. It even runs on the Steam Deck, although the graphics are not so good on there. Still, it’s playable and I will probably play there when it’s convenient.
IMO, ultra settings are for people with new, high end hardware and to future proof a game for at least a couple years. It’s not for people running a 2-3 year old rig with a 1080p GPU. Medium and high settings are generally good. Ultra is just like bonus mode for hardcore enthusiasts.
