Title: Protip: "Linearity" in controller setup.
Post by: Asdrael on November 27, 2017, 11:30:25 AM
Quite a few people have been complaining lately about the front brake being too brutal and the throttle response (of 450s in particular) being too unforgiving, causing front end wash-out, spinning or looping out from the rear.

To what I reply: "lol noobs".

More seriously, I think most people overlook their controller setup, in particular the "linearity" setting of their analog input. This controls how your controller input (CI) is translated into in game input (GI). Let me explain the linearity setting (when gain is at 100%):

What you always have:What linearity affects: everything in between.

Thanks alot for this Asdrael, these settings have helped me out massively!! i will include this in my next controller setup mate. thank you again, have a good weekend!

I may be the oddball but I find the controls much better with linearity 100%.  It allows you to use muscle memory a little better as you can properly judge how much more input will be needed.  It's not easy to judge how much will be given if the first 25% throw gives 10% braking power and the next 25% gives and additional 20% or 30% ( I know these numbers aren't accurate but it's just for representation purposes).  As you increase a control you are adding a multiplier to it which our brains can't accurately learn and predict as it is not linear. 

Adding different linearity settings is just a bandaid masking poor controller inputs, it might seem a bit easier at first but will hinder you in the long run with unpredictable inputs.

Too much throttle and brake problems should be remedied by learning to be more precise and altering the bike setup to suit.

While I see your train of thought I have to disagree, We tune Engines with Throttle curves and you handle that quite well. however I'm going to try your 100% a bit and see the results. you may be on to something by having a Curve present in the Physics Example The Throttle Curve. But than you overlay another Non Linear Curve into that one in the Controller and you wind up with a Double pendulum scenario? I Think?

This is good info. I speculated that the linearity setting had something to do with this, but hadn't really changed anything as of yet. Now I'm gonna try the 75% setting to see if it reduces my throttle and braking issues. No matter how delicate I try to be, its tough to gauge what is "enough" vs too much... until I hit the ground of course.
