Juddering zoom with x-52 Axis

[McVittees]

Now, here's a thing that has been bugging me from day one with BS but I've just lived with it: I currently have the zoom view action mapped to a rotary axis on my x-52 and often find I get a zoom-in / zoom-out 'juddering' that requires me to fiddle with the rotary until I find a sweet spot and it stops. I used to have zoom mapped to the slide control where it would also do the same thing.

 

Has anyone experienced a similar problem and did they come up with a solution? I have mapped the zoom to the rotary from within the game itself.

yes you will have these 'Juddering' (in middle position, not in full position) due to the X-52 sensor quality

 

i fixed the problem by capping à 70% the slider curve

so now when i'am at low position (Zoom out) i'am in the default Zoom (like ENTER key)

so my slider is never in a middle position.

 

hope it's help

best regards

Thanks for that Skypat - you seem to have the answers to all my questions lately! I take it you did your adustment in the BS axis mapping panel, not via the saitek software? Could you post a screen shot?

It's not limited to the Saitek, the Cougar [i know unbelievable] has the same issue.

It may be connected to the middle mouse wheel is by default set to zoom, perhaps deleting that setting my resolve the issue?

I have mine slaved to the "Z" slider and was getting the same "juddering". I fixed it a bit by opening up a bit wider "dead zone" in the Joystick config program. Now, as long as I get the slider pretty close to center, it stays rock solid.

I use the slider. And to prevent the judders on the slider, I created a rather large dead zone so that there are basically three stable settings to minimize the amount of judders. But I went through this rigorously with the X52 Pro and determined the zoom should NOT be done with the X52 profile. It needs to be configured in the slider axis in DCS to zoom. Notice the dead zones at the max zoom in and out. They are there so when you slide all the way in one direction, the judders are gone while you hold that zoom position. I also inverted the axis from its default to match zoom in and out with the slider. Of course, you can adjust it to your liking but here is the base settings.

This is not unique to BS either. I had the same issues in Lock On.

Does doing this mean you only have three different levels of zoom - min, normal and max? I was considering trying to map the view zoom to the mouse wheel on the Saitek - that works well you press the esc key and you get the mouse look activated because it zooms in discrete stops.

This looks very promising, even though i can't understand any of it. I'll have a look at the links in your sig when I get home.
