System up and running, pilot officer Slap almost ready for action

So far I've installed the steamy COD (and ROF) and now need to sort out my HOTAS/TrackIR settings etc
I had a quick fly/try and COD seems to be struggling with my GTX460 in general(jerky/low frame rates when around busy areas/multiple aircraft etc); most settings on medium I think. My first impressions where that, apart from the extra eye-candy, COD makes you "feel" more like your flying and interacting with surroundings when compared to IL2...Fab.
I'm really looking forwards to the ride as hardware and patches catch up...
Any advice of what in-game and graphic card settings one should be looking to tweak?
Cheers!
