I don't have a high-end rig either, but the game runs well enough on all planets. I really have no complaints about performance for the most part. Alderaan, however, absolutely wrecks the game and stresses the hell out of my computer. Insane planet loading-screen times, herky-jerk lag throughout the whole zone, and my computer sounds like it's going into overdrive. I don't have this problem on any other planet but Alderaan, so op I feel your pain.
