  mkdir -p ~/'.steam/root/compatibilitytools.d' && gio open ~/'.steam/root/compatibilitytools.d'

===== Monster Hunter World =====

  * Install from Steam or restore from backup through Steam
  * :!: Need to go to properties and force the use of a specific compatibility tool, specifically the one downloaded on the previous step
  * :!: This can take up to 20-30 minutes

===== mf-install =====

  * [[https://github.com/z0z0z/mf-install|z0z0z/mf-install GitHub]]

  * This fixes movie playback, notably trying to play back weapon preview videos
  * :!: If MH:W freezes when trying to play a movie, or for seemingly no reason, this may be required
  * :!: Observe [[https://github.com/ValveSoftware/Proton/issues/175|Proton issue #175]] and [[https://www.protondb.com/app/582010|ProtonDB]] to see if there's any reports related to this
  * :!: As of 2020/04/06, ''Proton-5.4-GE-3'' requires this
  * :!: Be aware of [[https://github.com/z0z0z/mf-install/issues/44|issue #44]] with CPUs with more than 8 cores

==== Download ====

****

  rm -Rf '/tmp/mf-install' && git clone --branch 'master' --depth '1' 'https://github.com/z0z0z/mf-install.git' '/tmp/mf-install' && sync

==== Install ====

  * :!: The ''PROTON'' environment variable needs to point to a folder containing the Proton compatibility tool planned to be used

  cd '/tmp/mf-install' && WINEPREFIX=~/'.steam/steam/steamapps/compatdata/582010/pfx' PROTON=~/'.steam/root/compatibilitytools.d/Proton-5.4-GE-3' ./mf-install.sh -proton

****

  cd ~ && rm -Rf '/tmp/mf-install' && sync

====== Steam Launcher ======

  * [[notes:wine#other|More Environment Variables]]
  * See [[https://github.com/ValveSoftware/Proton#runtime-config-options|Runtime Config Options]] for Proton-specific environment variables
  * :!: For any environment variables added, make sure ''%command%'' is placed at the end of the line

===== Log =====

  * Can be used to test if ''fsync'' is being used
  * :!: Probably shouldn't keep this enabled all the time

  PROTON_LOG=1 %command%

===== NVIDIA Optimus =====

  * If using [[http://download.nvidia.com/XFree86/Linux-x86_64/440.64/README/primerenderoffload.html|PRIME Render Offload]]

  __NV_PRIME_RENDER_OFFLOAD=1 __VK_LAYER_NV_optimus=NVIDIA_only %command%

====== Settings ======

  * :!: A lot of this needs verification and is quick observation

  * MH:W uses more video memory under this configuration (Proton + DXVK) than Windows 10 natively
  * :!: Use of High-resolution textures on a 6GB GTX 1060 at 1080p goes over 6GB of video memory usage, and causes significant performance drops
  * Volumetric lighting should be set to Low; doesn't seem to affect graphics quality, but hits performance hard above Low
  * Vsync should be disabled seemingly
