I agree that it lags behind where we look in Trackir. It's annoying and hard on the eyes to look out the corner of my eye. I'm blind in one eye and it's really bad looking out that side.
I pretty much don't use the HMCS because of it. I complained when the A-10C II first came out but nothing was done about it. It's too tempting to just leave it shut off, so i'm going to go back to flying the A-10C again. She's still a good plane and fun to fly. Lot's of missions and campaigns to do. Easier on the memory.
A good old farts plane. I just turned 80 a few days ago, so I qualify.
Good luck with the HMCS.
