I get 60 (limited by my monitor) or 1080ti. All settings maxed out at 4K

Nearly the same story for me on a 980 ti. I have to turn some settings down, but I get 60fps @ UHD commonly.

try uncapping your framerate, the game will let you run at higher than your hardware limit.

What CPU do you have? My 1070 plays doom at 4k no problem.

It is probably just that we have different standards of what a good fps is.

For me if its not at 60fps or more ALL the time I'm angry. Grew up playing Quake and Unreal Tournament pretty seriously.

For a more casual game like skyrim it might be fine for me.

If you played seriously then you knew enough to turn the settings lower, not higher.

The last thing you want is having your field of view obscured by colorful explosions, bloom, debris, etc. when your opponent has a crystal clear vision on you.

Yes, I am well aware of that.

But that is a completely orthogonal point to the question as to whether doom runs well at 4k with all features on. Because I am asking that question does not mean I would play death match that way. But I might indeed go through the single player campaign that way.

Indeed I didn't play Doom at 4k at all, because as I said, it felt like garbage at 4k, no matter what settings, on 1070
