Avatar72 Posted April 27, 2009 Posted April 27, 2009 First I want to say I read a few posts about similar issues but none seem to be similar to my own. Whats happening is when my zoom view is neutral (half way), extreme zoom in or extreme zoom out, everything is fine. But when you are in betwee those extremes, the View is jittering back and forth. its like watching your self zoom in and out real quick within one setting. Its not erraic behavior, its just annoying. I'm familiar with some of the other issue that cause extreme tracking problems and Im not having those. The Track IR track modes look good and are behaving. It doesnt seems to be a TRack Ir issue since there are areas within zooming that are just fine. It feels like its an in game issue. I havent experienced this jitter effect in any other game. When zooming in on controls, the back and forth effect makes clicking on control difficult as you can image.
Copperhead Posted April 27, 2009 Posted April 27, 2009 Are you zooming by shifting in your seat or are you using the zoom keys with your controller (eg. Saitek X52 pro)?
Avatar72 Posted April 27, 2009 Author Posted April 27, 2009 Heh. I guess I should have made that clear. I am actually using the zoom function. I'm using a Saitek 52 pro myself and I have one of the sliders mapped to a Zoom Axis. To be specific, its the turning slider button wrapped around the red thumb button on the collective.
Copperhead Posted April 27, 2009 Posted April 27, 2009 (edited) It's a common hardware problem on the Saitek X52 Pro. The slider is triggering signals even when it is still. The rapid switching between the zoom in and zoom out commands creates the jitters aka the shaking screen. There are 4 possible options: 1) Using the TrackIR software, shift the entire response curve (Z axis only) for the "Flight" profile upwards so that you get a more pronounced movement (look closer or pull back) when you move towards or away from the screen (The default value in the TrackIR profile is set too low). This alleviates the need to use the zoom keys as you will be using your head movements to control the zoom; or 2) Map the zoom function using the rotary knobs instead of the slider. The rotary knobs give a much more stable response than the slider; or 3) Adjust the dead zone for the slider in the BS "Axis Commands" screen so that you block out approx. 75% of the possible input (the middle portion of the slider), leaving the ends of the slider movement for zooming in or out. This avoids most of the problem spots in the slider, but you end up compressing the usable range into 2 narrow bands at the ends; or 4) Use a customized X52 Pro profile to create multiple deadzones along the length of the slider to compensate for the hardware jitters. The zooming will be performed in steps instead of a continuous zoom. However, as the false signals produced by slider are ignored, the jitters are avoided. I have uploaded the sample profile here: http://forums.eagle.ru/showthread.php?t=40856 Edited April 27, 2009 by Copperhead 1
Avatar72 Posted April 27, 2009 Author Posted April 27, 2009 Ok, my last response was a bit confusing. I actually am using a rotary knob. I just called it the slider and I mis spoke. The rotary knob around the red thumb button is the one I'm using. It was a nice convenient location for a widely used feature. Should I maybe use the slider instead and put a dead zone on it? The rotary causes the jitter too even with a small dead zone for it. It makes sense that it could be the Saitek though so I'm totally with you on that regard.
Avatar72 Posted April 27, 2009 Author Posted April 27, 2009 oh wow. I can see the Jitters in the Saitek Control Panel where you set deadzones for the axis controls. They occur in exactly the same places they do in game.
Copperhead Posted April 27, 2009 Posted April 27, 2009 (edited) Oops! My fault :P If you are using the rotary slider to map the zoom function, create 3 bands (NOT DIRECTIONAL AXIS) for the rotary using the Saitek SST software as follows: 0% - 40% ( / ) keypress 40% - 60% ( nothing ) 60% - 100% ( * ) keypress Do not map the rotary slider as the zoom axis under the BS "Axis Commands" screen.

Copperhead Posted April 27, 2009 Posted April 27, 2009 oh wow. I can see the Jitters in the Saitek Control Panel where you set deadzones for the axis controls. They occur in exactly the same places they do in game. Just leave the deadzone settings in the Saitek Control Panel at their default (that is, no deadzones). You can use the axis tune option in the BS "Axis Commands" screen to adjust the deadzone for the assigned X52 Pro joystick axis or slider within BS itself. 1
Avatar72 Posted April 27, 2009 Author Posted April 27, 2009 Ok, I've never messed with the Saitek Profiler before and I think I did it. I used the Bands like you suggested and its working. I like the other method better since I can get a neutral setting easier but this method will just take some getting used to. After all this though, I should probably just use the 4 way hat for zoom in and out as it accomplishes the same thing. I shouldn't need it since I'm using Track IR but if Track IR ever goes out like it sometimes does then I'm screwd. Thanks for your help. :thumbup: I learned something today about my $$ joystick :D +1 Rep for ya :)
