I am not one hundred percent sure what it is, but I almost feel as if mouse movement (ie: sweeping or tracking with the crosshair) is odd, especially with smaller movements. This is quite a hindrance when tracking a strafing player or someone who is quickly moving from out from cover.
For reference I have a DeathAdder 2013 and a Razer Goliathus mousepad (huge XL one). I don’t use any mouse accel and my mouse is set to 400dpi with a sensitivity of 10 in game.
This feeling I get does not exist in other FPS games I’m currently playing such as Quake or Battlefield. Nor did I notice it in Call of Duty or even another Unreal engine game, Smite. Although, in Smite, that precision is not as necessary so I’m not trying to track players.
I guess the best way I can describe what I am feeling is that with smaller movements I feel as if the crosshair is moving to fast and I’m overshooting my targets. In other games this would tell me that I need to lower my sensitivity, but I feel like my sensitivity is already lower than I would normally play with as my 360 is right about 17" across the mouse pad right now.
I actually also thought it may be the mousepad and it’s the quick, small movements that are just gliding across the pad, but then I realized I don’t get that same feeling in other games.
I’ll do some more investigating, but I know other people have expressed concerns and I’m wondering if anyone else can pinpoint their experience. As a side note I have this feeling with onethread off and on and I normally have over 120fps.
