3D graphics after win 8.1 update
I am Having a very similar issue, after updating to win 8.1, when I started GW2 I got 3D graphics that I cannot turn off the steroscopic option button is blank and will not turn on or off. I checked the drivers of my card, but it´s also up to date.
I had the same problem, but fixed it by turning off the 3d option for gw2 in the graphics card control panel itself.
ack i cant make blue red 3d mode go away!
I fixed it, thanks to the tip above. I changes the setting in the Nvidia control panel, that turned it off ingame to.
