Opentrack is twitching

Post by Kit Pepper » Wed May 05, 2021 3:41 pm

OK, so I thought I had my Opentrack headtracking working well enough to be able to function in Tobruk. It was smooth and had no problems... yesterday. Today however, (this is what I love about computers), without changing anything it's acting squirrely as hell, twitching so much that it's unusable. I can fly with it. I didn't change a thing. What gives? Anyone have this issue?

Probably some "Gain" settings need tweaking.
I found out the time of the day matters a lot, too. Damn sun interfering with the IR LEDs.

Try adjusting the gain settings until it only sees the 3 LEDs in a proper clear manner.

I'm not sure what you mean by "gain" settings. I will say though, that I have never had lighting issues before, and I eliminated that possibility by drawing the curtains, so the room is blacked out. It had no effect on the "twitching".

I deleted the app and downloaded the latest version on Opentrack 2.3.13, and it still is still twitching.
What drives me crazy is that it was fine yesterday, and for no apparent reason it's twitching today. And it's twitching so bad that it's impossible to use.

Can you do a screenshot of the Program while it is active?
Should look like this:

Maybe I can spot your problem.

I have this problem when there are light sources in view of the camera. When it worked was it later in the evening (no sun). Do you have a light on behind or reflecting off a surface behind the camera. This tends to confuse the head tracking.

My TrackIR 5 twitches in Cliffs too, which hella annoying but I haven't been able to fix it... Believe it's down to the reflectors on the hat getting a bit worn.

This is the gain setting that fixed my issues with the twitching:

Sorry I didn't get back sooner Kon. My gain is set the same as yours.

Rostic and I tried everything and couldn't find a fix. At supper time I gave up for the day.

We found that the "Status - Camera Info: " value is jumping (twitching) from 2/13/75 FPS very fast. All in a spit second, over and over. I think that is showing where the twitching is accruing, but we don't know how to make it stop. I believe that it should be stable at 75 FPS.
