======================================================
Get Lutris
Lutris Site:
https://lutris.net/
Once Lutris is installed, install SC from Lutris script
Lug-Helper
Run pre-flight checks using Lug-helper either from
GitHub: https://github.com/starcitizen-lug/lug-helper
or
Arch AUR: https://aur.archlinux.org/packages/lug-helper/
Once SC is installed you can use the LUG WINE runners from
DevNull:
https://github.com/gort818/wine-sc-lug/releases
NOTE FSYNC COMPATIBLE KERNEL REQUIRED:
Ubuntu/elementary OS/Pop!_OS users can check out XanMod for an fsync compatible kernel
======================================================
Increase the sysctl option vm.max_map_count to prevent
crashes due to memory allocation limits in areas with
lots of geometry:
Note I am running at 4K on 64GB RAM so my setting is 2100000000
For anyone running 1440p or 1080p with upto 32GB RAM use 16777216
sudo nano /etc/sysctl.conf
enter the sysctl option vm.max_map_count
vm.max_map_count = 2100000000
sudo nano /etc/sysctl.d/20-max_map_count.conf
enter the sysctl option vm.max_map_count to prevent crashes
due to memory allocation limits in areas with lots of geometry
vm.max_map_count = 2100000000
sudo nano /etc/systemd/system.conf
delete # from the line "DefaultLimitNOFILE" and set value to
DefaultLimitNOFILE=2100000000
sudo nano /etc/systemd/user.conf
delete # from the line "DefaultLimitNOFILE" and set value to
DefaultLimitNOFILE=2100000000
To temporarily increase this value enter this command in a terminal
sudo sysctl -w vm.max_map_count=2100000000
Output: vm.max_map_count = 2100000000
more /etc/systemd/system.conf | grep NOFILE
======================================================
Finally, to make sure your system is not starving Star Citizen of RAM,
you may want to change your "vm.swappiness" to 10.
The default is 60 meaning tthat your kernel will swap when RAM reaches
40% capacity. Setting it to “100” means that your kernel will try to
swap everything. Setting it to 10 (like I did on this tutorial) means
that swap will be used when RAM is 90% full, so if you have enough RAM memory,
this could be a safe option that would easily improve the performance of
your system.
To temprarily set vm.swappiness=10 do the following in the terminal:
sudo sysctl vm.swappiness=10
and enter the following to confirm the changes took hold
cat /proc/sys/vm/swappiness
For more permanent sollution simply open your "/etc/sysctl.conf" file from earlier
and add the line
vm.swappiness=10
