I think it's getting worse - or maybe I'm just noticing it more! - but even though I get perfectly good frame rates on unlimited (30 to 60 depending on scenery, weather and aircraft, as you would expect), panning with the spacebar round the vc is never really smooth, and sonetimes it's horribly jerky.
It's worse with the more complex aircraft and especially when glass screens are turned on, but it can also be quite bad with aircraft that just have steam gauges.
I've tried tweaking the settings but nothing has made it better.
Does anyone have any ideas please?
