Phoronix: 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...

Hmm, on the Arch based EndeavourOS it is already much higher:

vm.max_map_count = 2147483642

And the games just simply work.

I have /etc/sysctl.d/80-gamecompatibility.conf on arch maybe from wiki or other package

with

vm.max_map_count = 2147483642
vm.min_free_kbytes = 1048576​

Me too, had changed it a while ago. Still, nice of them to make it default.

I'm on EndeavourOS. Where is this set? I don't have such a file in "/etc/sysctl.d/" (only my personal swappiness.conf).

I havent had any issues myself. Mine is currently set for 524288, not sure from what

[theriddick]

still a common issue for new comers having it set way too low. Kind of wish steam had a way to handle this, or wine apps.

unless this was a very recent change, it isn't true, cuz i am on an endeavouros installation that is only a handful of months old and...

$ sysctl -a | grep max_map_count
vm.max_map_count = 65530

Manjaro on the other hand i recall did have this set higher by default.

.

My EndeavourOS is almost half a year old and I have a different setting for this (don't remember touching it ever):

$ stat / | awk '/Birth: /{print $2 " " substr($3,1,5)}'

Just checked my Manjaro it has 65530 like Arch. Recently installed/KDE edition YMMV.
