Some relief words for the developers and other players.
After installing last beta patch and running in full screen mode, all settings in high and eplepsy filter off... I have no more stutering!!! I said no stuter at all
AA 4x and vertical sync on too.
I have constant 30 fps over landscape and about 60 over sea. 25 fps over larger cities and that's it !!! (single player missions).
My hardware is below on my signature and I have the latest ATI drivers.
You developers are on the right path!!! Keep the good work and soon we will have everything running smooth
