I had an issue after i17 installed, my log in was OK but the charactor Screen for each of the servers had lines and was almost unviewable as if the video card had failed.
It is a new card and according to the new "Ultra Window" is able to handle the new settings.
I chose "no change" to my settings clicked on a random charactor and entered the game.
Screen was white and all I could see was My chars name and Arch, Target, Nav and Options, so I chose new ultra setting logged off then back on and all worked well, but a few lag issues required the new FSAA setting to be lowered to 4X, all is good now, still tweeking the settings to get optimal play.
Video Card: Geforce 9800GTX OC+
Driver: 6.14.11.9745
OS: WinXP Pro
