When you begin to Sprint, that very first second your moving faster but your gun isn’t swaying yet. There is a lot of things that don’t feel the same anymore and for some reason I couldn’t put my finger on it. I just realized that this is also one of the reasons why gameplay feels weird. The Sprint looks awkward until the animation kicks in. This makes it feel more disconnected if that makes sense.
In some cases it does start right away but a lot of the time it doesn’t.
