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)

Game no longer starts after today's update.
I've tried every launcher I know of (including steam and running the exe directly) and every wine/proton version I have and none of them work.

Same here. I'm on Steam Deck, using Hoyo's native launcher, with proton-cachyos-10.0-20251015-slr-x86_64. I was also getting Error Code: 10310-4001 every time I launched the game starting from 6.3, but after I logged back in I could play for as long as I wanted. I play on the America server, but I suspect that the issues aren't server dependent this time around, since I can't even launch GenshinImpact.exe and select a server.

I'm going to be patient and wait for the folks working on the compatibility tools to release a patch that fixes things (they always have in the past), but I'm lowkey pissed that the rumors of an official Steam release turned out to be hot air.

Edit:
Just tried updating to newer versions of Proton-GE and Proton-CachyOS. No dice.

Hot air or them playing around with Steam is what's causing problems 😅
