I concur, it works very well in AH2 now. The only problems are the limited views, and I don't think they're that much a problem since I still can use the view hat for six and high views.
I've been using TrackIR for 1.5 years now (version 1) and with IL2 I've had lots of happy moments. Now, I'm just Very Glad to have TrackIR support even with reduced six and high views

A happy camper, that's who I am.
