Just tried the patch and the game is a lot smoother over terrain. When everything is loaded into memory it's almost as smooth as water.
I still notice the stuttering when new things are loaded in but it happens for a second or two and then once the area is loaded its smooth flying. Makes me wonder how much smoother this would be if the game could access the rest of my RAM

.
Looks like I'll be starting the campaign real soon.
