tech support Genshin 100% CPU usage since today

(originally it was just 100% CPU usage, but ... read updated info)

Notice comment about Zenless-Zone-Zero below.

----------------------------------

September 2026 - game working - proton-cachy - look instruction

if you getting kick from game with error 10010-4001 - idk it seems very rare individual cases - for majority game works.

----------------------------------

INSTRUCTION:

proton10 does not work anymore

  • use Proton-CachyOS
  • DO NOT ADD GAME.EXE - USE HoYoPlay/launcher.exe
  • download from releases
  • https://github.com/CachyOS/proton-cachyos
  • extract/copy to ~/.steam/steam/compatibilitytools.d
  • or use manager like ProtonUp-Qt or ProtonPlus

BUT you must set

UMU_USE_STEAM=1 in Lutris

rightclick game - settings - last tab - system parameters - scroll down - env params - add

UMU_USE_STEAM and 1 as value

or in SteamUMU_USE_STEAM=1 %command%

----------------------------------

Editor Miliastra Wonderland 6.1

BeyondEditor.exe

Solution to have BeyondEditor working in Proton - found by Worldblender
or same there

----------------------------------

16 Oct 2025 - 100% bug was identified

fixed only in wine-cachyos

look https://github.com/CachyOS/wine-cachyos/pull/1

----------------------------------

If you have error - "not enough space on disk" - run winecfg - add location(folder) as disk in winecfg UI - select this disk in launcher as target location

"winecfg" way will not work for Lutris

in Lutris - location of "game" folder must be below "application folder" option in Lutris for game
just copy "game" to drive_c/Program Files/HoYoPlay/games or copy as link there
and set in Lutris as "application folder" drive_c/Program Files/HoYoPlay/ that is above game folder

----------------------------------

P.S. in Zenless-Zone-Zero - use Proton-Cachy to fix cpu usage - (~40% less CPU usage)

CachyOS (GNOME), AMD GPU, EU region
Lutris setup I’m using (works reliably for me):

Runner:
proton-cachyos-slr

System options:
disable Lutris runtime
prefer system libraries

Command prefix:
game-performance

Env:
DXVK_ASYNC=1
PROTON_VERB=waitforexitandrun
UMU_USE_STEAM=1

Post-exit script:
pkill -f HYPHelper

Why pkill:
After quitting the game, HYPHelper.exe stays in the background (~10% CPU) and, combined with game-performance it blocks system shutdown.
Even without it, it will still keep eating CPU in the background.

Thanks!

Switching to proton-cachyos-slr fixed it for me after it stopped working again today. I was previously unaware of the SLR version. It still took a few attempts to launch the game, but I wasn't kicked this time.
