playing on a clean reinstall with no addons or addon manager. happens rarely in open world and always in 5 mans and raids. really need help as it is unplayable in raiding. had this same problem in WoD and end of MoP and the little bit i played in legion. came back to game for shadowlands and it is still spotty lag spikes. latency is fine, running 32g ram, 6900K cpu, 1080ti, and game installed on ssd. Again no addons running, clean reinstall, trying everything to get this thing to run good again. home latency on average is 20, world is 40.
Came on here just to see if others were experiencing the same issue too. It might be related to this post: Freezing for short time on newer Nvidia drivers
mines been like this for years, its the main reason i quit in WoD
