2) The look mechanic for GTAV is very poor. If this were not GTAV the game may not have been supported. The look mechanic needs all the help it can get and the experience benefits from the assisted modes.
Yes, the look mechanic is poor, but the only real problem I see is the time-based acceleration. The strange response curve shouldn't be a huge problem, as there are no velocity jumps or anything.
So why not?
I'm asking cause I actually once measured the turn speed of 50 values, then assigned an interval of input to each of those with a Titan One script in order to make it as 1:1 as I could, but only vertically and horizontally, cause the game had a circular look mechanic and my script was already too big for T1. It worked to some surprisingly big extent.
My guess is that with the computing power of the XIM4, you might be able to make something 100x better than what I did.
