Yes, you can sync back before shutting down.

No you were right about the memory is much faster. My awnser was to some one who suggested that SSD drive would stop stutters. I was saying not so.

Sorry dude, i don`t believe, that you have no stutters with this settings and your midrange video card and amd cpu!

I even have stutters with 2500K @ 4.9GHz and 6970 and your settings!

Hit SHIFT TAB Then type the fps START SHOW and hit enter... then hit SHIFT TAB again.. that should open the console and set the fps meter to ON.

How much RAM and are you trying the RAM drive? I also am getting no stutter in free flight over land and an average FPS of 60. Still don't know if it's due to the RAM drive or not since I've spent most of the day mapping controls and then figuring out how to start a Hurricane!

There are stutters over London where the CPU is seemingly struggling, same when there are loads of planes. At least I can do small dogfights and learn how to fly fullreal until the next patch...

Well I probably can't help there. Try googling for a non-UAC workaround but I know I am running as Admin with UAC disabled (home machine, sure wouldn't do it on my work machine even though it has 16GB RAM!)

Maybe right-click ImDisk exe and Run as Admin?
Do you think it makes any difference which Ram disk tool I use?

Wouldn't think so...

I tried the ram disk solution, but I'm afraid it won't help CoD. I've checked and even made a 4 Gb ram disk and placed the entire 'parts' dir. on it, but stuttering was still there. The stutters are therefore not caused by slow and/or frequent hard disk access. It's the game and render engine that produce these stutters and is not related to hard disk access.
