SWTOR Graphic Bug

@AIanakin 

You can run a game repair per this guide link to be sure it isnt file related

This sorta looks like a thermal issue offhand, have you checked temps of the CPU etc when this appears ? did this appear after say 10 minutes for example 

Post a dxdiag per this guide link  initially

I tried the game repair but there is still the same problem, that appears as i run the game, from the first moment. Temps ranges from 80 to 85 degrees (°C).

Thank you so much, this solved all my problems.

When I tried to update my graphic card drivers, the auto-update system told me that the last update was already installed, but apparently that was wrong. With your help I can return playing this wonderful game. Thank you so much, you are the best. May the force be with you.
