First off, yes, you could say there are raids, like race wars if a race decides to do that.
For gfx, it depends on what gfx card you use. If you use ATI, download CCC aka catalys control center. If you already have it, which you should if you use ati, then just download it now, for the new CCC.
For Nvid... I don't remember, sorry. It's like you go into control panel in windows start > control panel and there should be some kind of Nvidia thing there.
EDIT: Welp the game keeps getting fkd over, with updates the community does not want. Now we cant even go back to newbie zone. Guess what, there is a portal, that you cant even see, no signs or anything about it, in newbie zone. You walk on it, BOOM you are taken to the main world, now you cant even come back, if you accidently left. Now players cant even go to newbie zone to help people. We dont want this, but meh, its not about what WE want, its about what the owner wants. Nice way to "make EA the way it should be, the way WE want it." Ha, who is WE? He and him?
Games do not run on a communist rule, if you ever notice, games that run like that, lose all player bases by a majority, and close down.
