When I have my laptop plugged into a 38" ultrawide monitor, I occasionally need to use more than one motion to get a window from the far side of the ultrawide monitor over and down to the laptop's built-in screen. But that doesn't feel too slow to me; rather, it's just that I'm moving the window a pretty large distance. For more reasonable distances, I have no trouble dragging windows or files around. I usually have my cursor speed set two ticks above default (leaving three faster settings available on the slider).
