Arch Linux Increasing Its vm.max_map_count To Help Steam Play Games & Other Software
Similar to Ubuntu 24.04 LTS, Fedora 39, and other recent Linux distributions increasing its vm.max_map_count default in order to satisfy some Windows games running under Valve's Steam Play (Proton) and other memory-intensive software, Arch Linux is also increasing its default value.
As explained previously on Phoronix, the vm.max_map_count sysctl value controls the operating system limits on the maximum number of memory map (mmap) areas that a process can have. This change should help address performance, crash or start-up issues for a number of memory intensive applications, particularly for (but not limited to) some Windows games played through Wine/Steam Proton. The sysctl vm.max_map_count threshold can still be overrode by the user if so desired.About The AuthorMichael Larabel is the principal author of Phoronix.com and founded the site in 2004 with a focus on enriching the Linux hardware experience.
