BioWare looking at SWTOR performance issues

Some players of Star Wars: The Old Republic have taken the game’s official forums to complain about performance issues that cause the framerate to drop drastically upon entering an interior location.
BioWare has responded with a note of their own, saying that the dev team are looking into the problem.
“Our development team and our production team have been investigating this issue and we want to thank everyone who has posted constructively on this thread,” wrote BioWare community rep ‘Arrthen’.
“You’ve provided the development team with a basis for investigation into the low FPS issues, and with your help they have identified and are in the process of resolving the indoor framerate drop.”
BioWare has promised that a more detailed note explaining the problem – and how they will fix it – will arrive shortly. In the mean time, players experiencing the problem are recommened to take the following steps:

Close any and all applications running in the background.
Turn down the in-game graphic settings.
Change the settings to favour performance over quality if you are using a third party graphic management software.
Turning off “bloom” in the graphic options in game.
Turning shadows off and shaders low.
Update your drivers.
