Jerky head movement with Track IR

Recommended Posts

I wonder if any one can help.When using FSX with Track IR 4, cockpit panning in VC is very jerky. This is true of both add-on aircraft (CJ1 and SF260) and default aircraftI have tried many different settings in the Track IR profiles but nothing seems to fix it.When I pan around with the hat switch, it's smooth as silk.I'm happy my track IR is ok, because in FS9 and Lock-On it's very smooth with the same profile.I run the latest driver 4.1.30 final B (excuse me if that's not exact)On to my system:Asus P5N32E SLi Plus latest bios2GB OCZ8500 RAM8800 GTX 768MB Graphics latest drivers 169.256600 C2D O/C'd to 2.9GHzAntec 600W PSUFSX SP2 (not acceleration)Vista Home Premium 32bit fully updatedMyTrafficX 5.1bASX SP2GEXFEXFS Genesis MeshSceneryTech landclass US and EuropeNhancer with recommended settings as read hereI run FSX with frames unlimited. I find if I limit to say 25 I never get 25. It's always 5 to 8 fps lower than the locked limit. It is much smoother with frames unlocked.Any ideas you lovely clever people?Stu

I've had this issue as well. I notised that the Staus was constantly switching between "Tracking" and "No Data" causing the jerky movement.One way to get around it (for me at least) was to click on the profiles tab and doubleclick on the Flight profile.Under the Motion" tab I ticked "Heads" and all was fine after that.I have no idea why that works for me - all i can say is that it helped me.

I guess my first question is: can you duplicate with FSX windowed, and with the head tracking window displayed in the TrackIR profile?That will tell you what data is in TrackIR.If that works correctly, you've ruled out interference in the hardware, such as a light or focus outside the capture window. Do you have an camera tracking add-on? Is your FPS high enough to sustain movement? Do you get the same behavior in an external view (spot view) or the 2D view (the panel will not move, the scenery will, a "feature" in FSX).Cheers,Etienne

>I noticed that the Status was>constantly switching between "Tracking" and "No Data" causing>the jerky movement.I had the exact same problem. Tracking was erratic unless I sat straight up in my chair so I was closer to the receiver. As soon as I slouched even a little, TIR would show no data.Then when I was troubleshooting I noticed that "Light Filtering" was set way too high in the "tracking settings" tab. I guess I could have just lowered the setting, but I unchecked it altogether and it works great.It's found in the main TIR window top header, View/Tracking/Settings

This is an important thread. I have the same issues. Possibly some of the good TrackIR support people will stop by and gives us some direction or links to support pages. I have kind of stopped using Track IR for this very reason. Is it simply related to frame rate speeds, or are there other possiblilities.Steve

I'll pipe in here too, having all but given up using TrackIr 4 w/ FSX. It's smooth as silk in FS9 also in the set up menus all works fine with smooth motion. Once FSX starts it's a stutter show. Simconnect? My system ? I dunno.cheersGreghttp://www.fs2crew.com/linepilot.jpg

Thank you all for your suggestions.I've tried the light filtering tip and it improved the situation. It still isn't as smooth as FS9 but it's better.It's nice to know others experience the same prob.Etienne asked about whether my system could maintain fps,generally, my system maintains about 25 to 33 fps on the ground and much higher towards 70 fps when at altitude.These figures are much lower around the major airports but still flyable... just.Maybe someone from Natural Point may have a suggestion.Stu

Hi Stu,I had this problem for a time (though for some strange reason, the problem has recently disappeared). At the time, following a suggestion by NaturalPoint's Vincent, I found that the erratic response was corrected when I ran Track IR with priority set to Above Normal. To make things easy, I used to start Track IR from a batch file as follows, which I stored on the desktop:CMD /C START/AboveNormal D:Progra~1Natura~1TrackIR4TrackIR.exe(my Program Files folder is on drive D:).Dugald

All good tips.........Check the tracking screen for stray IR light, you should only see 3 green.Are you running any antivirus/firewall software. These can cause issues withthe communication of SimConnect, within FSX itself.What type of add-on software do you have installed for FSX?Try increasing the priority of the software, within the task manager.If you are running Vista, make sure both FSX, and TrackIR are running as an Admin.

Thanks, Vince.I've responded to your email but I'm happy to communicate here.It may be useful as it seems just a few of us have the same problem.Stu

Any of those add-on applications have a head latency setting?Running any firewall, antivirus software?

Vince,None of those add-on programs have any such adjustments, they're graphical enhancements, in a very broad sense.I run NOD32 version 3.0.551.0. I have disabled this before but saw no benefit.I have Windows firewall on (Vista Home Premium 32bit)I could disable this, as my router includes a firewall but again, I've already tried this with no discernable benefit.Stu

The FPS you report should have very smooth reaction. I'm not sure you answered my question on whether the head gauge is smoothly tracking when you run FSX in windowed mode or not.We need to know to establish if it's a camera pickup issue or if it's in FSX.Regards,Etienne

The head gauge tracking is very smooth.There is also no light interference, I use the vector clip on a cap.TrackIR is perfectly smooth in FS9 and Lock-On Modern Air combat.I let the TrackIR choose a profile automatically when the programs boot.I have tried my own custom profile with no success.Also I've tried increasing TrackIR priority to 'above normal' with no success.Thank's for your supportStu.

Suggest you set you fps limit to 25. A movie plays at 24 so you only need about 20 or so to give an acceptable picture. When you set unlimited, you tell your computer to devote max resources to flying and leave little for anything else. Also, set Track IR to always run the flight profile.

Smooth tracking of the head gauges is a good thing as it eliminates the input.In 2D panel mode, is the scenery jerky or is the movement smooth (the panel will stay fixed, but the scenery will move in response to the head movement?It sounds to me like you have more than one thing competing for the camera placement/movement causing the jerkiness. The symptoms your provide are similar to FSCamera competing with TrackIR.

Do you guys have any table lamps or lights behind you that the TrackIR receiver can see? If you do it will cause the jerky movement you are talking about. I had this problem pop up one day and realized that it started when my wife turned a lamp on behind be across the room. I have to keep that light off to get smooth panning with TrackIR.Just thought I'd mention this.ron

>>>>>I run NOD32 version 3.0.551.0. I have disabled this before but saw no benefit.I noticed this because I run NOD32 and am having similar issues. I UNINSTALLED Nod32 and removed it from my system (subscription had run out anyways). Just completed a short test flight in FSX and it's working fine ! Simply disabling NOD32 from the front end doesn't shut it dowm completeley, if you check the Task Manager there is still processes running. Maybe try an Uninstall. I'm gonna look for another AV now :-)cheersGreghttp://www.fs2crew.com/linepilot.jpg

Ziporama,I tried panning in the 2d panel (default Baron) and the scenery pans smoothly. It also pans smoothly in the outside views.I don't have FS Camera by-the-way.Loop-n-roll mentioned about locking the frame rate but I will refer back to my original post, that if I lock the frame rate lower, say 25, I never achieve 25fps, it's always 5-8 fps lower. If I run unlimited, the sim reaches higher fps (dependent on location)and is much smoother.I think I should clarify that my settings are giving me good performance.When I pan around with my yoke hat switch, it is very smooth. It is just a matter of jerkiness when using TrackIR.I have already ruled out any extraneous light interference.There is a setting in FSX or TrackIR I feel is causing this. There are not many people suffering this problem, so hopefully there is a magic cure.I have gone around in circles with this on my own for many weeks and my post here is just a statement that my ideas have expired.Keep your thoughts coming and thanks.ThanksStu

Free your computer to do other processing by limiting frames. Also, panning with the hat switch requires almost no processor power but Track IR does. Also, FS9 needs a fraction of what FSX needs so I expect Track IR to run better with it.

Hi everyone,This jerky head movement with TrackIR 4 is back!I managed to cure it before, but I'm not sure how! I've just re-installed XP pro and put FSX on it's own drive.I set up my system according to Nick N's fabulous post and the overall performance of the sim and computer generally is much better than with Vista 32. I'm suffering exactly the symptoms as in my original post.I have no light interference and I am confident that TrackIR is correctly functioning. I only have the jerkyiness in FSX not FS9.This jerkiness happens when the scenery moves with head movement in 2d cockpit as well.In windowed mode, V sync isn't working and the picture 'tears' where it would stutter in full screen.I've tried setting TrackIR priority to above normal but it does not help.I've rebuilt my fsx config and only added the sim object line for MyTraffic and Disable PreLoad=1.Maybe NickN has some idea? I'm desperate now, I've been toiling with this for month's.Thanks in advance.StuOn to my system:Asus P5N32E SLi Plus latest bios4GB OCZ8500 RAM8800 GTX 768MB Graphics latest XP drivers 6600 C2D O/C'd to 2.9GHzAntec 600W PSUFSX SP2 (not acceleration)XP Pro SP2 all updatesMyTrafficX 5.1bRadar Contact 4ASX SP2GEX nhancedFEXFS Genesis MeshSceneryTech landclass US and EuropeNhancer with recommended settings as read here

Hi Stu,Did you solve this problem?A friend of mine "upgraded" from SP1 to SP2 and he now has the same problem. Before SP2 everything was fine. I guess maybe it is caused by SP2, did you try uninstalling it?
