Game client crash @ complete random times
Game crashes can be caused by a bad/corrupted video card driver, a bad connection between the mother board and your video card (if not built-in), too must dust and heat buildup in your computer case, etc. Try looking into those things, and dusting out your computer, and see if they help.
Me too, it’s happened twice in two days. Once was seconds away from taking Scarlet down. Didn’t get counted toward the achievement either time.
Someone on GW2guru.com also made the suggestion that with the new options to remove culling, all the extra sprites your video card has to draw is putting extra strain on it, the game, and your system. Try lowering your graphics settings and see if the crashes stop happening.
I have them too. Even after I updated my video card to the latest beta version.
