Ability/Loot Lag despite normal FPS and Latency

There is an ongoing issue with shard stability during times when the game population is high. Most frequently, this error will happen in Battle for Azeroth zones, or other places with recent world quests active (such as Warfronts). While there is no fix you can perform on your end, some players report that swapping between War Mode and Normal Mode can temporarily fix the issue, as it will place you in another shard which may be more stable. We understand that this is not an ideal solution, but it’s the most effective step we have available at this time.

We are actively working on fixing this problem with incremental improvements through game patches. Ion Hazzikostas addressed this topic in a WoW Q&A video.

If you are having this problem, please contribute to the thread for your region below:

Game Crashes on Launch on Windows 7 since 8.1.5

With patch 8.1.5, we added an updated version of DirectX 11. Windows 7 does not have access to the proper coding to run using this version of DirectX. Before trying other troubleshooting, enable DirectX 11 in Legacy Mode.

If this does not fix your issue, you can check our crash troubleshooting resources article for more help.

Black Screen on In-game Shop and “?” Help menu
Around the same time patch 8.2 hit, we noticed a number of players who were affected by an issue with the Razer overlay which caused the in-game shop and help menu to not display correctly. Razer has released a patch to their software to resolve this.

  • If you have or had a Razer device, uninstalling Synapse and reinstalling to the most updated Synapse 3 version should resolve the issue.
  • If you are getting black screens in either of these two menus and have never owned a Razer device, please see this article.

If you would like to use DirectX 12 on Windows 7, you will need to roll back to the last known stable driver (441.41) until a future driver is released which fixes the bug.
