Jerky head movement

[bunchy]

Vince, Any ideas on jerky head movement in game?

This problem has plagued me using TrackIR 4 with FSX.

I have latest drivers 4.10.34 and can confirm that there is no light interference causing this. Head tracking screens are fine.

I have uninstalled my antivirus (NOD32) to rule that out also.

Setting device priority to above normal has no effect... still jerky.

I have recently tried a different USB port and I receive a message saying 'Device will perform faster if connected to a USB 2.0 port, click for a list of available ports'

All available ports listed are usb 2.0 (ASUS P5N E SLi plus MB)with latest drivers on OS Win XP SP2. I have re-installed drivers to make sure.

The TrackIR is the only device displaying this and I have other USB 2.0 devices working normally.

Is this the cause of my continuing jerkiness problem?

The TrackIR used to be ok in FS9 but not FSX. Now it is jerky in both platforms. I feel I am going backwards with this TrackIR and it's just too expensive to disregard.

I have posted with this problem on Avsim sometime ago. I have managed to previously get it working great but it keeps regressing to jerkiness. Is the product faulty perhaps?

Product number xxxxxxx.

Please help!

So you did a clean install of the TrackIR software?

Any add-ons installed for FSX/FS9?

What version of Windows?

What version of FSX?

Video card/video card drivers?

The error you are seeing is an error in the chipset falsely detecting the TrackIR device, you can try updating the chipset firmware, or just ignore the error.

Ok, here are my system specs:

MB Asus P5N32 E SLi PLUS
4GB OCZ 8500 RAM
8800GTX 768MB Video card 169.21 drivers and nhancer latest version
E6600 CPU O/C'd to 2.87 GHz
Audiophile 2496 sound card latest drivers
2 X 300 GB Hitachi sataII drives (FSX on own drive)
XP dual core patch installed
XP Pro SP2 inc. all optional updates
FSX SP2 (not acceleration)
FSX add-ons:
GEX, FEX, UTX USA and Europe, ORBX,
FS9.1 add-ons:
Ground Environment Pro, Flight Environment, UTX-Canada, USA, Europe.
MB drivers: tried original and new Nvidia 9.64.
TrackIR software: tried original CD drivers and 4.10.34 final.

Before i installed the FS9 and FSX add-ons I had this jerkyiness problem.

The frustrating thing is, that I have managed to cure the jerkiness in the past but tried so many things, I can't remember if any one thing cured it or a combination of things. I simply cannot remedy it now, hence my cry for help.

When you reinstalled the software, did a clean install?

Can you send me a screen shot, of the tracking screen?

Profiles set to TrackClip Pro, or vector?

[bunchy]

Yes, clean install of everything, OS, drivers, software.

I use the vector clip on a cap.

Screenshot attached...... I think? FAQ says I need a web page! I can't even see an option to attach a file? I use Firefox by-the -way.

I have no web address to upload image to. Can you advise how to get you the screen shot?
