Guild Wars 2

Having this error as well. Nvidia card Quadro FX 3800m, I have tred ajusting some parameters, and today I adjusted the Physx configuration, I thought it was fixed played through the morning with no hiccups, but alast just tried to login and it blacked out on me… Unsure what to do next. It would be reassuring if we can get some kind of response from Anet. If nothing more than to say, “Ok we know about it and are working on it”
I will include a DX report:

The Pets taunt automatically, Try to use the attack my target F1 key before you start to attack the target that will enable the pet to pick up aggro first.
