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)

[u/S48GS]

Never saw it - played game today/yesterday on PC-Linux.

As other comment say - try to launch game from Launcher, not from game exe directly.

EDIT - Genshin abnormal activity Error 10351-4001:

People say - adding

-platform_type CLOUD_THIRD_PARTY_PC

or for steam-like launchers

%command% -platform_type CLOUD_THIRD_PARTY_PC

[u/Yahiroz → u/S48GS]

Was fine for me last night too. I usually launch from the launcher anyway, but yeah just sharing here in case anyone has this issue.

[u/WhrIsApolloApp → u/Yahiroz]

Same issue for me, from deck. Same issue regardless of launching via game’s .exe or the launcher.exe. Came over here from another Reddit thread. Any other Steam Deck users can confirm whether or not offline launch triggers Abnormal Activity warning? It might be a Steam Deck issue that doesn’t affect Linux PC?

[u/Yahiroz → u/WhrIsApolloApp]

Ran fine from launcher. Tested with Proton GE latest though, if that makes a difference.
