I've got an ATI HD 4200 series.
I played the Beta perfectly fine, ran smooth, etc.
I updated my graphics are the request of the full game when I installed it and when I was playing today I had a ton of graphics issues.

I get holes in the terrain, some spells don't display properly. On the 'lobby' menu when sitting in a party waiting to launch the game, my character has holes through him.. I get huge lines just randomly through stuff.

I'm curious if anyone has an idea to fix this.. especially since the beta played flawlessly.
