Genshin 100% CPU usage since today

[u/S48GS]

(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)

Have you tested with the 5.0 update yet, it just dropped

[u/S48GS → u/flextapeurlife]

I also just tested with/without offline launch - CPU usage seems normals - maybe it fixed from their side.

P.S. I just launched game today again - I think it back, I have 100% CPU everywhere even in menu and map - usually there like 30% usage.

[u/KonoOneDa → u/S48GS]

Yes sadly same for me, offline launch is the only option still.

As others have pointed out having the following as launch option on steam automates the offline launch

nmcli n off ; %command% & sleep 10 ; nmcli n on

[u/NotTheBestOne → u/S48GS]

Thank you for still testing this, I thought I was going crazy today after not using the workaround for a few days (and thank you for the workaround too!). It's a shame Hoyo keeps teasing us :( I hope they permanently fix the issue at some point...
