I start TrackIR 4.0 software, to control a TrackIR 5 camera (KSP doesn't support TrackIR 5 software yet). Then I start KSP and load a game. When the spaceport appears, headtracking is inoperative nine times out of ten. When I alt-tab to TrackIR, it has crashed (grayed-out windows, "TrackIR.exe has stopped working... details... APPCRASH in Stackhash_0a9e") . So I quit KSP, restart TrackIR, restart KSP, and then all is well (nine times out of nine).

How can I make TrackIR work the first time? (Should I buy a pre-5 camera from someone on ebay?)

KSP 1.0. Clean optical environment: other than teensy dots from eyeglasses reflection, the camera isn't confused about which blobs are the tracking markers. The TrackIR camera driver is, which is up to date.

Edit: TrackIR loosely falls under the topic "game-specific hardware." Certainly it is marketed and used primarily as a game controller, even if it isn't specific to KSP. So if this question is re-opened, I'll answer it as: either update the source code of KerbTrack, or buy a pre-5 TrackIR camera.

  • I think that this is not a question you should ask to us. I think that contacting TrackIR devs can be your best shot.

    is purely a hardware/driver related question.

  • But TrackIR doesn't crash with non-KSP games. And I'll bet you dollars to doughnuts that a dev's only answer would be "upgrade to 5.0". forum.kerbalspaceprogram.com/threads/73184 claims support only for 4.0 cameras, so maybe working with a 5.0 camera at ALL is lucky. Then the answer may really be either ebay a 4.0 camera, or head over to github and write a 5.0 driver myself... Aug 22, 2015 at 20:55

Either update the source code of the KerbTrack plugin to handle TrackIR 5.0, or buy a TrackIR camera that is older than version 5.0.
