don't know if this helps. In the properties for SWTOR the box "run in 680" is checked and cannot be unchecked
You also really need to install windows 7 service pack 1 and other updates
Try the below
You can do so as follows:•Press the [Windows] Key + [R] at the same time. (The [Windows] key is the key with the Windows icon on it)
•Copy the following in to the text box and press ok: %localappdata%\swtor\swtor\settings
•Open the client_settings.ini file and ensure the following are displayed within, or edit/add if so required:
Fullscreen = false
D3DFullScreen = false
RefreshRate = 60
NativeHeight = 768
NativeWidth = 1024
Height = 768
Width = 1024
•Save and close the file.
•Start the game as normal.
•Change graphic settings within the game as desired.
