John5 Posted Monday at 03:20 AM Posted Monday at 03:20 AM (edited) Video of bug. HMD alignment will "jump" up when aligning, causing the alignment to be incorrect even if fine alignment is used to correct the error. Random occurrence, cannot reliably reproduce. Reslotting does not fix the issue. In the video, even though the cross was spot on after aligning and doing fine alignment, the alignment is evidently incorrect. I'm using TrackIR 5. Unable to provide track file due to file size. Edited Monday at 03:20 AM by John5

I would try doing this in reverse and see if it reoccurs. 1
Foka Posted Monday at 10:21 AM Posted Monday at 10:21 AM SA data is not a good way to verify alignment. Data is updated every 12 seconds, if I remember correctly, so some differences are expected. Try in the air and designate ground target, and see if HMD shows that correctly. Or TGP symbol.

Regardless, I do not anticipate this is expected behavior. 14 hours ago, Foka said: SA data is not a good way to verify alignment.

I do realize the update frequency of SA data. However, in DCS, when it updates it should be accurately placed at the update interval, which you can clearly see from the video it is not. Designating an A/G target would produce the same result. I cannot reliably reproduce this bug - it seems to happen randomly but I haven't yet dedicated time to try to reproduce it. If you compare this video to a normal HMD alignment, the same "jump" occurs, but with a correctly functioning alignment it jumps down and then back to the original location. When this bug occurs, it does not first jump down and simply jumps up and out of alignment (but then can't be corrected).

Correct the SA data has a delay so wont be spot on. Forum rules - DCS Crashing?

The update delay is entirely irrelevant to the point. I don't know how it should behave IRL, but when the HMD is aligned properly in DCS, at the moment the update occurs, the positions are correct. You can clearly see from the video they are not. If I were to take off and have a target locked the HMD would be positioned well above where it should be relative to the target. Same could be demonstrated by an A/G designation. 8 hours ago, Muchocracker said: Doesn't mean much.
