I had a friend come over and check this out, so its not just me.
The first screenshot shows the path where i am running back and forth. Certain spots cause certain graphical errors. This started right after I was moved from an emptying black citadel map. If it was doing it before that, I didn’t notice. I then had a friend come join me in black citadel, who had been in a Plains of Ashford beforehand, and had her run back and forth in the same place, and had the same issue.
Running outside that ranged caused all graphics and stuff to go back to normal, but as soon as you run back in, it would happen again. Leaving the map and coming back has the same results, as does completely exiting the game and logging back in. Neither of us had any graphical issues anywhere else in game.
Here are the screenshots? Not sure if its just us or what.
P.S.: Not sure if you know but if you need to attach more than 1 image you can. Just select an image and then use Preview, it will save that image and give you an option to add an image again.
