Mouse Controls for EPIC

So, are Mouse controls based on the Engine or the way the devs implement it?. I have heard both ways. Unfortunately I do not have any videos to show in regards to the smoothness in each game. Maybe I will try and make one! In response in an example of where I have experienced and saw this was Ground Branch a military tac shooter being made with UE4 and is still in the works. Go download the tech demo for free at their website and do the firing range. For the second part get Insurgency if you can afford it. I think it’s like 4.99 CDN right now on Steam and play that game and see how much more smooth the mouse is.

Hope this helps you understand a little more.
