8.3 is very buggy for a lot of people. It seems to freeze for 1-5 seconds, then crashes my graphics driver (short black screen or freeze) and then it resumes.
If you have task manager open in another window you can see WoW’s memory usage jump up several gigabytes while it is frozen. Sometimes it will drop to 350MB after a freeze and othertimes it will just keep increasing. Wow is using 11GB ram right now after about 3 freezes without restarting.
People on the US forums having the same problem:
This did not occur before 8.3 (I have not changed anything) and have tried turning off all addons, reinstalling the driver with DDU, scan and repair, etc
!!! EDIT: ----> Changing to Direct X 11 Legacy is a temporary fix, however it comes with a severe FPS penalty
EDIT2: @Blizz, I think it would be in order to refund our Horrific Vision tickets considering how unforgiving the system is and you guys releasing a clearly very buggy client.
EDIT3: Seems to have been fixed now
