I've been playing at max sensitivity with a mouse for about 8 months now and recently I noticed that when I move my hand how I feel like I normally do the cursor isn't where I tried to move it. My windows sensitivity is already at max and I even tried using a different mouse but nothing seems to work. I think that my hand movements are moving so little now that I may need a higher sensitivity to play. For those of you who'll say just move your hand more it makes my movements very inaccurate and uncomfortable to play.
