Blizzard have posted an update with the issues they’re working to improve on the Diablo 4 Beta.
Known Issues (Source)
Hello everyone –
Diablo IV Open Beta has begun and we want to thank everyone for jumping back into the world of Sanctuary. These beta tests are a crucial part of our development and help us make the game experience better for everyone as we head toward launch in June. Today, we have seen more players than ever log into the game. We are excited to see all the enthusiasm about the game and the two new available classes for testing (Druid & Necromancer) this weekend.
We want to provide an update on some of the major items the team is currently working on after the start of Open Beta earlier this morning.
We are looking at an issue where players disconnect from the game and are unable to rejoin after disconnecting. This is tied to a few other items that players are experiencing such as party errors and some network performance issues in-game.
There is an issue where Windows 11 users may run into a crash upon alt-tabbing while in Fullscreen. We do have a workaround for that and it is located here on this thread 4.
Some users are also experiencing issues with in-game voice dialogue. A workaround for this issue is for users to leave the game and go into their game settings and adjust language settings to English. English is currently the only available language available for voice dialogue in beta. We will have other languages available in the final game.
Beyond this list, the team is working on many other reported items and capturing them so we can address them either during beta or before launch.
As we noted earlier this week, we do expect queue times this weekend while we manage the flow of players in-game as we tackle these issues. We expect queue times to fluctuate depending on the time of day and traffic depending on where you are located. There may be a time where we need to take the servers down to perform maintenance and to push out an update. We will make sure to notify the community beforehand when and if that occurs.
We will continue providing updates either later this evening or tomorrow morning (PDT) once we have additional information.
Thank you again for the enthusiasm and feedback as we help bring Diablo IV to everyone come June.
