I'm not sure to understand what "hitching" is, but if, by chance, your are referring to the blurriness when you turn around, it's a designed feature that can be deactivated in the settings. LIkewise, there's a "tunnel"-effect when you speed up.

If it's more like a visual stutter, then the issue is on your end, and you should check your FPS. Look for Valheim or Unity tweaks on YT; they say that there are some lines to change in the .ini files, but I can't warrant the result.
