I thought I might share this thread in case people are suffering from FPS issues since the patch. It basically resets the settings:

Greetings all. I know we have all been having trouble with the new patch and fps. I actually did something that returned my game to pre-1.1 fps and graphics. I saw this hinted to in another post, and I just want to verify that it worked for me.
So, what I did was go to my settings folder (C:\Users\Jae\AppData\Local\SWTOR\swtor\settings), do not paste this into your search bar, because it has my name in it, but follow a similar path. Take your client_settings.ini and Graphics_mirror.ini files out of that folder and move them to the desktop (in case this doesn't work). Then load the game normally, and at the character selection screen, bring up your graphic settings and change them as you desire and apply. Then spawn in.
My fps went right back to where I had managed to get them pre-1.1 after this short process. Hope it helps someone else.
