You need to remove as much extraneous infra red as you can Latrobe, track ir is sensitive to it (causes all sorts of weirdness). Suggest a couple of thick blankets to block out all infrared sources (sun etc). I always close the curtains irrespective of time of day when I'm using mine.
Once you've done that, adjust the light filtering, until you can only see the 3 reflective strips on your hatband. Then you should be good to go - remember to adjust your profile to as aggressive as you can stand it (lemme know if you want a copy of mine, if you do, sling me a pm with an email addy and it'll be on its way as soon as I pick it up. My profile isnt too aggressive as yet, but seems to work pretty well as a start point) (If anyone else wants it, pm me an addy)
Make sure you have it set to vector to ensure you can see all 3 points on your hat.
HTH,
