It shows you working longer on this
That first result was pretty nice sad that you kicked it out
Im a little disturbed that control looks also much smother then the current which seems to stuck some cycles not sliding the head at all like she would reject some cycles before going down on it
Im pretty sure mouse isn't stuck but not seeing the cursor makes it hard to see if the drag path might be not good.
Though should be a straight line to the right.
Also strange because his movements do not get stuck to the left and are continuously the same movement pattern.
Doesn't look like a input/output latency issue at all.
Though it looks like it's dependent on the Mouse Movement speed for her more then for him that's strange.
Doesn't works as flawless as in your first Video at all.
