First, let me acknowledge that I know this is a very complicated fix... but is bioware doing anything about the fps issues for "Higher-End" Machines?
I can run any other game (Including Battlefield 3, Call of Duty, and yes... WoW) on max settings, and still get 100+ fps.
While SWTOR solo play runs at high framerates, most of the group play (mostly pvp: Ilum/Warzones) runs at a crawling speed of 10-20 Frames.
