For those wondering about how to set the AA. I'll credit Remanz for finding the right info for that one.

Anyway, you'll need to edit client_settings.ini located in the directory:
\Users\<USERNAME>\AppData\Local\SWTOR\swtor\settin gs

The best settings I found was adding the two following lines before [Game]:

AntiAliasingLevel = 1
DebugAdvEnviroLighting = true

You can set the AA to 16 or whatever else here, but if you're running nvidia card(s), all you need to do is set it to anything over 0, then you can override or enhance it within nvidia control panel. I'm running tri-sli 580s, and since the game doesn't utilize sli (nor does it need to), I run it @ 96x CSAA which puts all 3 cards @ about 95+% usage, but makes everything look very smooth.
