Lately I have been getting black screens randomly while playing, still hearing some ambient music, no menus are visible, but I don't get a crash or error code and have to close GW2 from either task manager or the Windows menu bar. The only thing I've changed from the last time I've played without experiencing this was a driver update on an Nvidia GTX 1080. Hoping its just a driver issue but the game was patched a few times since playing on my desktop. Was playing on my laptop with the same drivers on a different graphics card and it had no issues (sli 755m)
