My PC Specs:
While playing the game at some random times I will start to suffer input delay on both my keyboard and mouse, after a short moment it will go back to normal.
To understand what I mean I'll use the following example.
Running forward during a strike, release the forward key to see my character still moving forward.
This can happen while turning, moving, or aiming.
I have nothing running in the background that could be using resources to cause delays.
