Permissions

For Wine to be able to use the STAGING_RT_PRIORITY_SERVER environment variable
Allows rtprio up to 94 and nice up to 10
May also allow Realtime priorities to be used with other applications
TODO: Apparently you can use a username instead of a group?

RT Priority Permissions

This makes the assumption that the current user is also part of a group with the same name (2023: This is the case for Fedora 39, openSUSE TW, and Ubuntu 23.10)
Verify groups with the groups command

groups

sudo mkdir -p '/etc/security/limits.d' && echo -e "@CHANGEME - rtprio 94\n@CHANGEME - nice -10" | sudo tee '/etc/security/limits.d/99-realtime.conf' > '/dev/null' && sudo sed -i 's/'CHANGEME'/'$USER'/g' '/etc/security/limits.d/99-realtime.conf' && cat '/etc/security/limits.d/99-realtime.conf'

Default: 0
Ideal: 94

Increase Open Files Limit

For Wine to be able to use the WINEESYNC environment variable optimally

sudo mkdir -p '/etc/systemd/system.conf.d' '/etc/systemd/user.conf.d' && echo -e "[Manager]\nDefaultLimitNOFILE=1048576" | sudo tee '/etc/systemd/system.conf.d/nofile.conf' > '/dev/null' && echo -e "[Manager]\nDefaultLimitNOFILE=1048576" | sudo tee '/etc/systemd/user.conf.d/nofile.conf' > '/dev/null' && cat '/etc/systemd/system.conf.d/nofile.conf' '/etc/systemd/user.conf.d/nofile.conf'
