Jerky periferal movement with newest patch

[blitzen]

I play primarily Il-2 Flight sim with Track IR4 + Vector & hat( which has very little difference in this sim...) Until recently I had very smooth side to side movement with this device 9 i loved it!) BUT since newest Track IR patch download I have been experiencing two things I used to have alot of back when i owned Track IR2...that is - even when I've "centered device( f12) head movements tend to favor looks to right , so I get vision over to rear of cockpit, but I can usual get only half way to the left side ( i.e. can only look over at a 90 degree angle..) I can counter this somewhat by turning my headslightly to the right & hitting f12.but this gets tiring to do & a recenter during game play screws everything up again...#2 I no longer have smooth movement right to left & back again side to side.Things tend to hold up or get caught on the edges so up to about 90degress on either side movement is fine ...after that there is a moment of full stop ...then movement to rear of cockpit.As you can imagine this can be very irritating in the middle of life & death virtual flying.I need help & need it now - what can I do to get back to those wonderful trouble free days,aside from full reinstall?

-I took another look at settings & discovered I hadn't ticked Track IR hat...so thats apparently where the problem was - tried a flight everything is now as good as gold...except for FPS that could always be better....

Blitzen I would sugest for starters trying a different cap and push the cap further back so that the reflectors are facing straight at the camera. Then try moving the camera forward or back a little or even possibly giving the from of the camera a little wipe.

Give these a go for starters.
Good Luck
