Question on axis saturation

[rrohde]

Just wondering - what does the saturation slider in the DCS Axis Tune options do, exactly? :music_whistling:

 

Thanks.

Thanks.

Try it, it's pretty obvious.

Basically the axis tune options transforms joystick values into in-game values.

Saturation Y will limit the maximum value that can be reached in-game.

Saturation X will reduce the joystick value requred to reach maximum in-game value.

 

ex:

Y 70% means that in-game value will range -70% to 70%

X 45% means that maximum in-game value will be reached at 45% of joystick travel.

 

in-game-value = MAX(Curve(joystick-value/saturation-X) * saturation-Y, saturation-Y)

 

Curve(value) transforms the value with constraint that Curve(-1)=-1 and Curve(1)=1

Thanks for the detailed info, PiedDroit!

 

So what's a good reason for me to set those saturation values up? I am trying to understand when I would use saturation values, and what benefit they might bring me.

You're welcome :thumbup:

 

You might want to use saturation X to create a kind of deadzone at the end of the joystick's range.

Let's say your throttle is a bit wobbly and never goes fully 100%

Or maybe you don't feel comfortable pushing the stick full right so you'd prefer the ingame stick to reach maximum deflection before hitting maximum physical limit.

 

Saturation Y is used when the maximum deflection in-game is too much for you. For example, a TDC is moving so fast that you can't control it.

Or you don't need full stick range ingame and want to use the maximum physical stick range for better precision.

 

There is usually no point using both X and Y at the same time as they cancel each other, except for Y that also sets the max in-game value.

 

Saturation Y and Curvature can both be used to increase precision.

Saturation Y will keep movement linear but will prevent you to reach maximum in-game value.

Curvature will increase precision near the center then precision will decrease to allow reach max value. As such, it is non-linear.

 

Hope I'm clear :smartass:

That's very useful information, PiedDroit! Thanks for explaining this by including some use-cases for these X and Y saturation values. Going to play with those now! :)

Just found this post now, excellent explanation PiedDroit. Thanks a lot !!! :thumbup::thumbup:
