Where exactly do you change these bands? Would someone please explain this to me like I'm an idiot (because I probably am).

I remember seeing this setup page a long time ago, but haven't been able to find it since.

Deadband and filtering (adjusted from the ingame Hardware Setup/Input screen in the game, alternatively some joystick drivers also have the feature) work as follows.

Deadband (also known as Dead Zone) is a means of dealing with joysticks that exhibit unstable behaviour in the centred position. This can be caused by mechanical reasons (worn pivots or sagging springs) or by electronic reasons (worn pots, poor soldering, susceptibility to induced electrical noise). It works by ignoring a portion of the control input at the "neutral" part of the axis travel. For joystick/rudder, this will be at the center of the travel, for throttle at the start.

In some of the joystick drivers that offer this feature, you can also set it up to ignore the extremes of travel (full input).

The slider (in the game version, in driver versions sometimes other graphical schemes are used) controls how much of the travel is ignored. You can see the effect in the game screen, the red square shows what information the joystick is sending, the green one shows what the game is doing with the information.


Filtering is used to address instability in the off neutral parts of the joystick travel. Normally the game uses whatever information the joystick is sending right now, but worn (and in some cheap sticks, even brand new) joystick often send a signal that jumps around a bit, making it hard to hold aim or level flight.

To address this, filtering allows you to make the game use an average of joystick samples over a short period of time. This means the game wont respond to a change in joystick information until the joystick remains changed for a bit. The more you move the slider to the right, the longer the period of time the game uses to average input.

----------------

The down sides:

Deadband: Because the game is using a reduced part of the range to for control input, your ability to make fine adjustments is reduced. If you dont' adjust your first one or two sensitivity sliders down to near or at zero (number of sliders depends on amount of deadband used) you'll also find that when the joystick is moved far enough to get out of the dead band, you get a sudden jump from no input to too much when you're looking for small control adjustments.

Filtering: because the game is using an average input, you'll get a delay in response when you want to make rapid control movements. The more filtering you apply, the more control lag you'll suffer.

I keep finding my posts in FAQ's and guides. They're usually good enough to ask before including them, but I've usually forgotten by the time I find the finished product http://ubbxforums.ubi.com/infopop/emoticons/icon_wink.gif

Thanks for the info. But where exactly do I change these bands?

When I right click on the FB settings and go into the joystick properties, under game Controllers I only have two tabs"test" & "settings." I can only calibrate the basic movement of the stick.

I'm using a Saitek st-90, btw.

Start the game and click the Hardware Setup button at the bottom right of the main menu. From there, click the Input button. That will take you to the in game joystick sensitivity settings, including deadband & filtering.

Thanks - that was a big help. I'll play around a little bit.

I saw the settings on the other post. What does everyone else use?

Just my 2 pennies worth.

I DO NOT touch any of the joystick settings in FB. Instead I just use the profile settings for my joystick using the drivers for the stick.

I used to mix my profile and FB settings and it got too complex, then when I had to reinstall it was a nightmare. Just do one or the other, not both! Much easier.
