So yesterday I nuked my FF XIV client, uninstalled my video drivers, uninstalled my video card (from device manager, not physically), cleaned the registry, rebooted. Then I reinstalled the video drivers and finally re-installed the FF XIV client.

And after an hour or so of playing today, the client crashed again. So the procedure didn't help in my case.

Looks like the same error to my un-trained eyes:
