Hey

I just spent nearly 2 months messing with my mouse settings/ Camera control in swtor. derp.. ye.

anyway i found the answer in a post in one of the forums here.

You need to edit the (account name) account.ini file

AppData\Local\SWTOR\swtor\settings\(account name)_account.ini

find this setting: Controls_CameraRotationSpeed = 0.41

0.41 is the speed i chose, you should experiment till it works for you

The last bit is to change the graphics setting to windowed,fullscreen .

i wish i had looked this up 2 months ago...lol. hope this helps folk
