Looks like I'm going to have to scrub my flight, something has gone funky. My cockpit view is juttering backwards and forwards in the Z axis, like the pilot is having some kind of seizure. I've tried clearing out the view settings in DCS:A10, I've updated TrackIR, nothing...and it's given me a headache.
TrackIR is showing no problems when I alt-tab out of it, so I suspect it's a conflicting setting somewhere, but damned if I can find it, so I'll probably just play Minecraft tonight, or Xcom since that's probably what Hunter and Raptor will do.
