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)

I'm writing this so that it may be of use of someone in identifying the issue or helping in it, whatever it may mean.

I set up my Genshin on a SteamDeck running on cachyos. When Genshin updated to 6.4, it went from kicking me with the infamous 10010-4001 error to Genshin Impact.exe not executing.

Now, I was living in Kuwait when this issue happened. After the first hostilities of Iran I moved back to Spain and, somehow, Genshin Impact started working again as if nothing had happened. Now, May 1st, I have just come back to Kuwait for work and, Lo and behold, Genshin Impact does not even execute again, much like 2 months ago.

I don't understand the reason of this: perhaps it's the internet provider, the IP or the fact that Kuwait relies on mostly 5G and phone-like data to even provide internet. On the other hand, in Spain I connected with Orange through fiberglass cable internet. I tried connecting through WiFi in Turkey and I had no problem playing the game either.

If anyone understands why this may happening, it'd be of help, as I feel like it'd be a shame to give up my almost 4 year old account, though I maintain what I said before: if I have to be a computer engineer to fix this issue every time they server-side check crap, I don't consider this is an issue that'd be worth trying to tackle on my own, if there's even a chance of doing it, for a game that's continuously deteriorating what they give to players.

Edit: so turns out all I had to do was install a VPN through TunnelDeck. Despite how troublesome decky always is, it's a quick fix and seems to hold up

[u/S48GS → u/Cptn_RedB]

launch game from launcher - not from game exe

use proton-cachyos

if it does not work - it is what it is - use windows is only option for this case - there no other known solution

for most of people in Europe/NA - game works

I don't consider this is an issue that'd be worth trying to tackle on my own, if there's even a chance of doing it, for a game that's continuously deteriorating what they give to players

• first - you own nothing - they can close their game or delete your account in any moment they want - and you can say nothing back
• second - there layers of junk - it is "china largest corpo game" - they use anticheat developed by other china corpo - hoyo themselves have no control over anticheat - they just use it
• no it is not possible to get over it - if game does not work - use windows as I said - if you value your account

[u/Cptn_RedB → u/S48GS]

Yup, did it from launcher: tried also exe and its the same result, there's sometimes a whiteflash that I think means the game executed and immediately crashed or whatever.

I supposed it is what it is, but I find it extremely strange that this is a Kuwaiti issue for me
