Jittery view while looking around in FSX with T-IR 5

[caaront]

I love T-IR 5 and have no other issues with it.

When I look at one spot without moving my head I have a perfect view, it's also perfect when tilting my head from side to side, moving/zooming forwards and backwards, and side to side.

But when I look outside the aircraft and then move my view by turning my head up or down, left or right, the view is jittery, and then when I stop it is perfect.

For instance, lets say I am flying down the runway and look at the terminal building on my left which is way ahead of me, as long as I keep my head still I can see the terminal perfectly, and I can read the name of the airp[ot on the terminal.

But as I get closer to it if I turn my head to look at the terminal as I pass by it is jittery and I cannot read the name on the terminal or any of the signage, until I once again hold my head still.

Can anyone help me?

Thank you.

As I raised the frame limits the jittering disappeared.

I have since changed my OS to W-7 and installed a GTX 480 and the movements are silky smooth at 60 FPS.
