Probably mentioned earlier, but if you have an AMD card/cards and are experiencing stuttering, force a 59 or 60fps (I use 59, as some say it works better) limit. I use MSI Afterburner with the Rivatuner API detection to do this. I tried fiddling around with RadeonPro, but the recent releases have pretty much broken it for me with regards to overclocking/game detection.
Setting a limit to my fps of 59 was like night and day and the stuttering is completely gone with crossfire 5850s and 12.11 beta 11. I downsample 2560x1440 with generally all high settings and HBAO and nearly max out that 59fps in most scenarios.
This helped with BF3 as well btw, but it was mainly FC3s stuttering that was atrocious. I was like all the other posters too. Fraps would report great framerates, but the performance felt terrible.
EDIT: Try the new driver first I guess, but my solution will help if that fails.
EDIT2: I should have really mentioned how you do it. Obviously, install MSI Afterburner and go into settings to make sure the OSD is turned on. A Rivatuner tray icon will appear when its turned on. You can even assign hotkeys to toggle the OSD etc so you don't need to see it, or set it on/off per application profile. Add FC3.exe in Rivatuner and then select the wrench icon in the top right of the prog. Set your fps limit to 59 and apply.
