Had a crash upon loading the game at the time i had throtled my DNS so when DNS issues occur it may have some hicups that lead to crash i suspect, but pure speculation haven’t had crashes again also Firefox is constantly crashing when scrolling thru websites with lots of gifs playing all at same time like imgur tenor reddit etc, these sites you do not want active in background while playing wow could lead to these crashes, always suspected it was related its kind of confirmed right now.
Discord for example pauses gifs if app not in focus if configured at default, so does steam, not sure if chrome does as well.
Anyway i got 1000 hours on record without crash ignoring that one time crash that might be related to me having throtled my dns servers.
my crash recovered within 5 seconds there was no freeze just a stutter.
