there are many times where computer & object interactions, melee attacks, hit and other animations have significant lag time or don't activate at all. (especially Melee)
Not only does the game look cheap, but it also makes the controls feel broken & unresponsive. These things are pretty core to how people respond to gameplay & hurt the experience enough to be fixed relatively soon, but much of this stuff is beta issues.
It's not just some "art bug" it hurts the feel of the gameplay. when I feel I need to keep pressing a button because there is no measurable response from my character, that should be considered at pretty substantial issue.
