The disabled full screen opt did not help me and I do not use steam. So far day 3 no crash after locking my overlock with EVGA precision 1, locking FPS to 72 in game settings, and setting graphics to standard. This is a shit bandaid since I have been playing on max for years, but it works. 10 pvp games, 5 alliance raids, and a hades farm party (got the mount btw) and no crashing. For my system this is the fix i7700k/270z/1080/32gb3200ram all OC

To the SE mod who is going to copy paste an answer here. Please tell people to attempt the fix I have when this problem comes up in the future <3
