On Xbox?
My dude, I have an i7-8700K and a 1080Ti and it ran like a bundle of ass pirates. It's going to fuck your Xbox in the face. Warhorse is a small studio, you're getting a certain degree of eurojank here. I'd be surprised if you got a solid 30fps with how intensive it is.
For the game itself, it is what it is. Swordplay is fun until you realize that damage is tied to the sword stat. By the end of the game I was dropping dudes in full plate (helmet included) with face stabs. You feel most immersed when you're poor and broke.
Story had it's high points, but the ending is a GIANT blue ball party. I'm not gonna ruin it for you, but I was really pissed once everything went down. If you're cool with the veneer of realism and you don't mind not being able to autosave, I'd play it up until the last mission lol. Haven't tried the DLCs yet.
