This game plays like butter. I average 110fps and "drop" to 75ish on Ilum when there are four gajillion people on the bridge.
Out of what I have seen, most of the people having problems with their "high-end" systems are usually running some form of AMD hardware. Whether it is an ATI card or an AMD CPU, it seems to be the culprit.
Maybe the code just seems to favor Intel and Nvidia.
