Integrated graphic cards do not seem to support the game, so you need to upgrade your drivers. When I would check for driver upgrades on my computer none would show up, but then I purchased Driver Genius Professional for $30 and was able to get updates. Once you go to the new drivers then you should be all set.

I have heard that they may fix this in a patch but I'm not sure when/if that will happen. So, you could wait and possibly save $30 but it is worth it to get the program anyways in my opinion to keep your computer optimal.

The issue caused me a lot of frustration so I figured I'd share this knowledge on the forums to hopefully help others with this issue. If ya have anymore questions just contact me or search the swtor forums, which is where I found this out.
