My desktop is a 3Ghz Core 2 duo with 4GB RAM and plenty of free HD space. I've tried defragmenting, just to be sure that it wasn't a disk issue. But for some reason the game starts to chug pretty hard, especially after visiting the pocket dimension. What's odd about this is that I also play the game on a Macbook Air, and I see no performance issues there, even though the Air is significantly less powerful than the desktop (which ran SWTOR at high detail with no problems). Any idea what could be causing this?
