To complete the list of products: In addition to games, this change is also useful for users of Elasticsearch and/or Opensearch and Apache Lucene/Solr on large clusters.
Elasticsearch also suggests raising the value, although not so high: https://www.elastic.co/guide/en/elasticsearch/reference/current/vm-max-map-count.html Opensearch: https://opensearch.org/docs/latest/install-and-configure/install-opensearch/index/#important-settings Apache Solr: https://solr.apache.org/guide/solr/latest/deployment-guide/taking-solr-to-production.html If you e.g. start Elasticsearch without a large enough vm.max_map_count, it will print a log message to raise it and exit. My personal opinion: Actually the game issues described here should better be fixed in Steam's launcher when starting such a game (or in Wine). The downstream software should better ask the user to raise the value upon starting. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to procps in Ubuntu. https://bugs.launchpad.net/bugs/2057792 Title: Some Games are crashing linked to a vm_max_map_count too low Status in gamemode package in Ubuntu: Confirmed Status in linux package in Ubuntu: Won't Fix Status in procps package in Ubuntu: Fix Released Bug description: Hello there, I submit this request to improve the gaming experience in ubuntu for all users. Today, Hogwarts Legacy, Star Citizen and few more games are crashing or just not starting because the vm_max_map_count is locked at 65530. If we change this value to a value > 200000, all games are working well and there is no bug linked to maps. Some others distribution like Fedora or Pop OS, have already made the change few month before. It's time to Ubuntu to makes the change also. Thanks in advance for applying this request.
