The game is the third installment in the Diablo franchise and was released in the Americas, Europe, South Korea, and Taiwan on May 15, 2012. Since its release, Diablo 3 has seen a number of updates and changes, most notably the addition of the Crusader class in patch 2.0.3. In March 2014, Blizzard released the first expansion pack for the game, titled Reaper of Souls. This expansion added a new class, the Crusader, as well as a new act set in the world of Westmarch. In May 2012, Blizzard launched the Diablo 3 public beta test. This allowed players to try out the game before its release. The beta test ended on May 1, 2012. Since its release, Diablo 3 has been a commercial success. In the first 24 hours of its release, the game sold over 3.5 million copies. As of June 2013, the game has sold over 15 million copies.
A cache is a temporary storage location for frequently accessed data. Caches are used in order to improve the speed and performance of data retrieval. When it comes to Diablo 3, the game services that are cached include the game's client, login server, and authentication server. Caching these services can help to improve the game's overall performance and stability.
Although the caches for Diablo 3 services have been improved, there are still some players who are unhappy with the game's performance. Blizzard is continuing to work on improving the game's infrastructure, and hopefully players will see more improvements in the future.
