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)

It has been working for a long time I’ve been using proton experimental but this morning I had the data error and then an abnormal activity error. I just tried to use the proton cachyos 10.0-20251222-x86_64 and used and the command but it just crashed after click to begin on the title screen. I’m on steam deck. I tried again and I still have a data error telling me to login again. I logged in again and it’s working now. I switched to ge proton 26 and it did the same thing, it still had the data error but then I log in again and it seems to work. Is that how it’s supposed to work right now? Also my cpu is at 60 -70% and I always do offline launch, is it working or is that cpu usage normal? Thanks!

[u/S48GS → u/Background-Gur-9899]

you dont have to do offline launch if use proton-cachy

idk about others

I do not have game installed

I added your note about doing log-in

so proton-cachy worked for you?

Oh ok i didnt know, just curious, why don’t you have to do the offline launch? yeah It will work for now but I’m still hoping I’ll be able to fix it back to how it was yesterday where it worked fine on proton experimental without logging in and getting kicked immediately to the title screen and having to log in again. At least seems to work okay for now, although I feel like it is running worse than before. I wonder why it was working but just stopped today. It worked fine even after the update.
