===== ACO - Faster Compiling (AMD Only) =====

This changes the compiling from LLVM to ACO which is considerably faster.

See

  * https://youtu.be/6T_-HMkgxt0
  * https://youtu.be/fm_mzPBnWB0

You do need up-to-date drivers mesa 20+ and edit /etc/environment.

Add this to /etc/environment

<file bash /etc/environment>
RADV_PERFTEST=aco
</file>

----

===== Wine Dependancies and Lutris =====

There are several packages that wine, proton and lutris game installs need.

It is recommended installing all the dependancies before installing lutris.

==== Ubuntu/Mint/Pop OS! 20 ====

<code bash>
sudo add-apt-repository 'deb https://dl.winehq.org/wine-builds/ubuntu/ focal main' -y
sudo add-apt-repository ppa:lutris-team/lutris -y
sudo apt update
sudo apt-get install --install-recommends winehq-staging -y
sudo apt-get install libgnutls30:i386 libldap-2.4-2:i386 libgpg-error0:i386 libxml2:i386 libasound2-plugins:i386 libsdl2-2.0-0:i386 libfreetype6:i386 libdbus-1-3:i386 libsqlite3-0:i386 -y
sudo apt-get install lutris -y
</code>

----

==== Arch-Based Distros ====

<code bash>
sudo pacman -S wine-staging giflib lib32-giflib libpng lib32-libpng libldap lib32-libldap gnutls lib32-gnutls mpg123 lib32-mpg123 openal lib32-openal v4l-utils lib32-v4l-utils libpulse lib32-libpulse libgpg-error lib32-libgpg-error alsa-plugins lib32-alsa-plugins alsa-lib lib32-alsa-lib libjpeg-turbo lib32-libjpeg-turbo sqlite lib32-sqlite libxcomposite lib32-libxcomposite libxinerama lib32-libgcrypt libgcrypt lib32-libxinerama ncurses lib32-ncurses opencl-icd-loader lib32-opencl-icd-loader libxslt lib32-libxslt libva lib32-libva gtk3 lib32-gtk3 gst-plugins-base-libs lib32-gst-plugins-base-libs vulkan-icd-loader lib32-vulkan-icd-loader lutris -y
</code>

----

===== ESync - Helps Game Overhead =====

Check to see if esync is enabled already (most distributions do by default)

<code bash>
ulimit -Hn
</code>


If this returns more than 500,000 than ESYNC IS ENABLED! If not, proceed with these instructions:

Change the following files and add this line to the bottom

/etc/systemd/system.conf & /etc/systemd/user.conf

<file bash /etc/systemd/system.conf>
DefaultLimitNOFILE=524288
</file>

<file bash /etc/systemd/user.conf>
DefaultLimitNOFILE=524288
</file>



/etc/security/limits.conf

<file bash /etc/security/limits.conf>
username hard nofile 524288
</file>

<WRAP important>
**IMPORTANT:**  Change username to your username!!!

  * Steam - Go to Launch options for the game of choice and type in <code bash>gamemoderun %command%</code>
  * Terminal - type <code bash>gamemoderun ./game</code>
  * Gnome Tool - If you use GNOME Desktop Environment install this extension: https://extensions.gnome.org/extension/1852/gamemode/

----

===== Custom Proton =====

The stock steam proton is rather old and behind the Wine team.

Which means there are a lot of performance tweaks and improvements that you aren’t getting yet.

It is therefore recommended that you install Custom proton which should provide a considerable improvement when gaming in Steam.

<WRAP info>
**NOTE:**  DO NOT USE STEAM IN A FLATPAK!  You will lose some performance and modifications are more difficult!
</WRAP>

Source Project: https://github.com/GloriousEggroll/proton-ge-custom#manual

Auto-Install Project: https://github.com/Termuellinator/ProtonUpdater

For Installation, we will use the ProtonUpdater script on GitHub.

<code bash>
cd ~
wget https://raw.githubusercontent.com/Termuellinator/ProtonUpdater/master/cproton.sh
sudo chmod +x cproton.sh
./cproton.sh
</code>
