Some of us have been trying to get to the root of the problem in the tech help areas here and in the official TW site - the biggest culprit seems to be Particle Effects, although in some cases AA can contribute. If you are experiencing stuttering, with inexplicably no fps loss (how that happens I don't know), turn down your particle effects to MEDIUM. You can get away with high particle effects, but everything else will have to be turned to near minimum.
