reported Movement of HMCS Symbols when moving head while aircraft is banked

[Luft Waffel]

Hello,

 

There is a bug that occurs that causes all of the 3D markers to be inaccurate on the HMCS in the following conditions:

 

To replicate this easily:
1. Have a designated target somewhere, the further away the better, since the error in absolute position will be larger

2. Turn on HMCS and look at the target diamond

3. Roll the aircraft as close as you can to 90 degrees angle of bank and hold it there

4. Move your head from side to side and up and down slightly using track IR or VR, you'll notice it most in VR, make sure you keep the markers within the display limits

5. The marker moves around as you move your head, causing its position to be inaccurate unless you look perfectly directly at it

 

Exactly the same render logic bug existed on the A-10C II Scorpion HMD but was fixed very quickly since it was much more noticeable, but the problem is still present on the hornet and F-16. Its harder to notice if you test it using A/A radar-locks, but again its easier to notice on a target further away since the error in absolute position of the target is larger. 

 

Its probably also an issue for the DL contacts displayed in the HMD, but its probably hardest to notice there as there is already a lot of error due to the refresh rate which of course is not a bug. Again though, if you try it on something further away you will notice it more.

 

The issue exists for any markers that represent a 3D location in the world.

 

EDIT: Added a track replay - (it should be easy to replicate by just following the instructions though)

Edited to add track replay as requested

Nice catch, thanks. Also noticed it with the ATFLIR waypoint symbols. Reported both.

I can confirm this. Also, the target reticle will wander off target as well within 2nm half the time. Ill try to post a track of this myself too.
