TrackIR Settings

After some additional tests, I have found some erratic movements when using "turbulent motion" and "vibration" effects from DHM menu. If I disable such items, the jumps disappear.

For me, the problem is when using some DHM effects, not TIR interface. Without effects, TIR is absolutely smooth. My hardware is capable to move Prepar3D at a reasonable FPS (locked at 30)

I have used 18, 16 and 14 ms. All of them have the same problem.

I am almost there, set scan speed to 30, got quite some improvement. Still 2.28.1
Thanks

Try Smooth Camera Transition setting right up to 100 the max and make sure everything is smooth. Assuming the drivers are OK then I have a sneaking suspicion your system will not be able to show a smooth camera transition or AHM motion since FSX simply cannot cope or process the 6DOF updates smoothly enough.   Stephen

Test 1 Smooth Camera Transitions: 4 new cameras created for testing purposes, all 4 cameras set to 100% camera transition speed.  Cycling between cameras results in smooth transitions. My personal preference would be to see slower transition speeds but that is not the point here.

Test 2 AHM movements: Tested using default AHM settings with Enable Smooth Head Movements ticked, some stuttering is evident but for what it's worth frame rate remains steady at 30fps where it is locked.

I have this occasional jerkiness or spiking as well.  How do I adjust the scan time? I can't figure out where to access that setting.

I adjusted the scan time to 36 and now. I love it.

Sounds like you've fixed the problem here by allowing users to adjust the settings to suit their particular system in every conceivable way....now, about those winds aloft??  Gribble gribble!!

Well, I spoke too soon.  The jerking or flicker still happens with the scan speed set to 28, although it seems improved to a tolerable frequency. 

I am using Track IR 4 hardware with V5.1.3 software.

What profile in TrackIR do I use? Do I need to set anything in the TrackIR software before using the livecam function? These may have been answered in these threads but I can't see anything specific.

thanks

Ah well. I have tried to get TrackIR to stop juddering but I give up for now. I have disabled all cams and gone back to EZCA. I now only use the weather engine part which is what I wanted anyway and well worth the price just for that!

I will revisit the cam side of things after xmas when more features etc are added.

Try fiddling with the scan rate within Opus. My TIR was "jumping" as well, seeming to flick back momentarily to the default "dead ahead" position for that camera. I adjusted the scan rate slightly and it totally fixed the problem.

We have found that it is very easy to go too fast for FSX to cope, under such circumstances FSX seems to throw away the 6DOF requests until it can once again cope, hence some of the stuttering. We are now experiencing some of these issues with LC control and having to slow things down a touch so that everything remains in sync.

I'd still like to know what settings to try to get back 180 degree range of motion.  

Hmmm...that's not my experience.  I have changed the XYZ scaling from 1.00 through to 2.00 without any change in the final degree of movement.  It always stops at about 160 degrees.  As I said, it didn't used to until I upgraded to the latest version, so something must have changed.  

Yes, as I said in my first message, I have adjusted the speed and smoothness and also the profile curves (not something I've had to do with prior versions) in order to even go beyond 90 degrees.  When I first tried Opus, I was unable to get TrackIR to go beyond about 100-110 degrees, if you'll recall, and something you did in one of the versions fixed that problem.  I then set up speed and smoothness in TrackIR so that I could look fully behind me and had smooth movement.  Then I installed the latest release version, and once again I could only look about 90-100 degrees.  So I changed speed and smoothness again, without much effect.  So I have to significantly alter my profile curves so that I could even get close to 180 degrees (about 160).  I then tried changing the scaling, but changes there have had no effect.  It was working fine, and now it's not, and I've changed nothing else, so something you've changed in the latest release version or the betas leading up to it (that I didn't install) is preventing full range of motion again.  

I've left PBY scaling at default.  I tried adjusting it a small amount, but noticed no difference, so put it back at default.  I was surprised that scaling didn't seem to have an effect.  Perhaps it did in some way, but not with respect to the limit of motion. 

If I have a chance, I'll uninstall and reinstall the 1.24 version and recheck as well. 

Okay, I won't roll back.  I'll try adjusting the scaling again and see, but I've tried already.  

AHA!  So, as I said, I only adjusted the PBY scaling a little, since I thought it would be XYZ scaling that would matter.  I adjusted it from .75, which was the default, to .85, and didn't notice a difference.  I've just tried it again, and I noticed a slight difference (say 5 degrees further back).  So I kept adjusting and, viola, that is the issue.  It seems the PBY scaling sets a hard limit to how far behind one can look.  At 1.00, it appears to be 180 degrees.  Higher settings mean I can look more than 180 degrees behind me. 

I hadn't noticed a hard limit when looking around before.  Is that something added since the last full release version?  I kind of like it, actually, now that I know how to adjust it.  It prevents the Exorcist head movement possibilities I used to have.  I can still get those if I want -- a PBY setting of about 1.5 seems to allow me to pivot my head completely around and look out the front of the plane again. :-)

So, I've set it to 1.00 and now have full range to behond the plane.  Really makes it a lot easier when I'm flying MP, as I mostly do, and need to look behind me to see where others are at (which is usually behind me). 

So, what does PBY mean, anyway?  XYZ I think I understand.

Thanks for the explanation and the help.  Just flew a circuit in the A2A Cub with the new settings and all is well!  Great weather too!  Bowerman appears to be SVFR at the moment!  :-)

I've had to adjust speed and smoothing.  It appears that .5 speed and full 50 smoothing gives the best results now.  I started out with 1.0 and 10, but have progressively decreased the former and increased the latter.  That seems to change with each release, but I suspect we are settling in on final settings for the TrackIR interface now.  And it's a matter of preference as well.  I don't like my head to move too fast. 

That will be nice.  EZDOK has such a feature, but I found it so cumbersome that I never used it.  As it is now, I just have that axis with a pretty flat line so that I can't move to that side very much.  I know most people don't like to mess with curves, but you really can set up TrackIR to do pretty much what you want it to do by means of them.  

Yes, I wouldn't think it should be a priority.  Of course, setting up the curve in TrackIR is independent of the aircraft one is in, and so doesn't really stop me from moving outside the cockpit. The ability to adjust limits for each aircraft while setting up cameras so that one is kept in the cockpit would be very nice.  But you have a lot on your plate, and I think most people can live without that feature until you have more time for it.
