Drag Scroll
I am a player that will use drag scroll extensively, I noticed that if one drag scrolls too far the cursor will lock to the edge of the screen. This limits the distance one may drag scroll to a function of the mouse's sensitivity, if I am understanding how this works correctly. This is interesting, by default the mouse sensitivity seems a bit off. In general I will use 1200 dpi but I find that 2000 dpi feels closer to what I am used to when playing this game. I only mention this because it will also limit drag scroll distance as the cursor hits the edge of the screen faster.
