Today i downloaded new beta Nvidia drivers while game was down,when i tried to run game again i saw that graphics became very ugly,is it about those drivers or its because of the patch?
That happened to me sometime in the year, what i found out was that the new drivers were automatically setting the game to run off the onboard graphics, i now have to manually select to use GPU when starting up the client. Not sure if this is the same issue you are having tho. But i have not experienced any problems with this new update or any of my guild mates.
Perhaps a driver rollback?
