  • Benefits from a Fsync-compatible kernel
  • Benefits or requires GloriousEggroll's custom Proton build



sudo dnf install 'steam'

Custom Proton

  • :!: Proton-5.5-GE-1 did not fix video playback, and introduces an issue with exiting the game
  • Proton-5.4-GE-3 is fine
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


  • 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 Proton issue #175 and 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 issue #44 with CPUs with more than 8 cores


rm -Rf '/tmp/mf-install' && git clone --branch 'master' --depth '1' '' '/tmp/mf-install' && sync


  • :!: 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' ./ -proton


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

Steam Launcher


  • 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

__NV_PRIME_RENDER_OFFLOAD=1 __VK_LAYER_NV_optimus=NVIDIA_only %command%


  • :!: 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
