Thanks for posting FS Phat.
I tried your settings, including forcing AFR. I had experimented with RadeonPro previously and provided my results in roadczar's previous thread.

The lost planet profile is a no go for me given the terrible flickering as reported by other 5970 owners, but a few of the other profiles seem to do the trick (I mainly have been trying the Dirt2 profile).
I get an initial FPS of around 90 or so which is a noticeable improvement over using RadeonPro without forcing AFR as I had been doing previously. I use a variation of the stock QMB Manston attack mission for all this testing, so there are quite a few other aircraft in the game, but nothing over the top.
I am, however, having the same problems I reported in the previous thread in that the FPS soon diminishes by well over half. The funny thing is, i noticed this time that the huge drop in FPS can be reproduced
every time by my simply moving my head (TrackIR) to look over one of my shoulders!!
Basically, I am on the runway looking ahead, I play around with the cockpit instruments etc and as long as i am looking ahead, my FPS stays generally between 80-90...but if i quickly look over, say, my right shoulder, the FPS drops down to between 20-40 and then stays there for the remainder of the mission. If I exit the flight, go back to the menu and start a new mission, the FPS remains stuck at the lower figures. This happens every time. Its as if something breaks the RadeonPro settings and the benefits never return unless I log out of the game totally, shut down steam and then start it all up again.
I cant for the life of me understand why simply looking over my shoulder/changing my view could have such a ridiculous effect on the game's performance. Especially as the reduced FPS remains even if I restart a fresh mission, and I get the lower FPS in the same situation where I was getting 80-90 previously.
Any ideas guys?
I know this sounds too ridiculous to be true by the way, I swear it is however!
