CPUs without Advanced Vector Extension fall below the recommended specs for Diablo 2: Resurrected, although the team has been working on a fix to allow these older generation CPUs to run the remastered version of the game.
There is currently a fix for these issues, however, it may affect all players even if they have up-to-date processors so further testing will need to be done over the next few days to ensure little errors as possible for the entire player base.
Players who purchased the game, and cannot play due to these errors, are able to request a refund through Blizzard's Customer Service channels.
Blizzard Looking To Fix Advanced Vector Extension Issues For Diablo 2: Resurrected
Diablo 2: Resurrected is a faithful remaster of the original game that was released in 2000, with two different options to play as.
Play with the original graphics from the 2000s or play through the game with the all-new remastered graphics and cinematics.
Because the original game was released in 2000, this may be why Blizzard would like as many people to access the game as possible, even if their platform of choice is below the recommended specs of the game.
There are future updates planned to add a competitive ladder to the game shortly after launch once all the server issues have been smoothed out.
The developers also have not ruled out new content for the game in the future, although Diablo 4 will take priority in the Diablo team.
Expect to see a fix for this Advanced Vector Extension issue over the next few days, once the QA team is satisfied it won't cause additional issues for the wider player base.
Diablo 2: Resurrected is now out and available on PC, Xbox Series X|S, Xbox One, PS5, PS4, and the Nintendo Switch.
