Those don’t help dude.


Open CMD and type taskkill /f /t /im dllhost.exe, it worked.
If I could have some feedback to know if it was right ?

The only way to fix it in a not ackward way right now is to completely restart your computer like I don’t even wanna login right now due to that.

nope. core number 2 is still at full utilization

i exited the game, and it’s still running till now on steam

Hmm it’s to close the game when it’s still displayed running in steam.
You have to look at what takes processor time in the task manager → Processes + Details*.

yes it’s still show as running. i exited the game. i edited the post there

This issue seems to have surfaced with the latest patch. Potentially connected to the attempt of fixing the connectivity issues (just speculation at this point, because no commication from AGS.)

The only solution, that I have heard of so far is restarting your computer.
Restarting steam does NOT work. There also is nothing in your Task Manager to manually end. Even if you close Steam for 5minutes or longer, the game itself is still running somewhere somehow.
And no matter how much I looked so far, I couldn’t find it at all. But I am not experienced enough on this topic to find the root of the problem :laughing:

Can you make a tasklist and tell me the processes that correspond to the PID that failed on the screen ?

but i try terminating it thru task manager. firefox closed. but core 1 still at full power

i already restart my pc now. will try again later when lost ark is stuck again

It is curious because firefox does not use dllhost.exe so I do not understand why this message is displayed.

It worked for one person but he had no problem with his processor running abnormally high.

Nope, this is purely EAC’s fault, other EAC games like Apex and BF2042 Fall Guys etc is all having this issue, EAC f’d up real bad


yep the process thats running to high is system and is not closable… did all trouble shooting with eac without any change… gonna try one more time i quess… the dcs was already anoing enough to make me wanna check out out the next poe league… gonna be honest ill probebly never quit this game but im am done swiping until **** gets fixed an might take a break untill brell… i love this game but i also love poe and wanna check out d4… when bugs happens in poe they work 24/7 untill its fixed while here they dont even adress issues in the forums just copy paste the same trouble sghoting guide for everything… man i dont know i im just sad about the constant issues

Aahhhh yesss… I forgot about that part.
Will try again later :+1:

Hi everyone,

I don’t think this has anything to do with a GPU driver update.
I do think this is an EAC issue.

I have managed to get the CPU core #1 ( the second core ) to not be at 100% utilisation.
Uninstall EAC to fix the problem.

I have a thread with my notes in it here
Lost Ark will not stop in Steam - Game Support / English Support - Lost Ark Forums (

One more on the list of “EAC bad”.

what do you mean by “Unistall EAC”? Just deleting the folder?

Hi @tobix, you can run the EAC setup program and the is an uninstall function from within that program. Deleting the folder is probably not a good idea.

Troubleshooting EAC Issues - Support | Amazon Games
One of the options on that page details how to uninstall and reinstall EAC.

Repair Service, Reinstall, Update, or Verify EAC
To repair Easy Anti-Cheat:

  1. Open the Lost Ark Application in your Steam library.
  2. Open Settings, select Manage, and then Browse Local Files.
  3. Go to Steam > steamapps > common > Lost Ark > Binaries > Win64 and open the EasyAntiCheat folder.
  4. Right click the EasyAntiCheat_Setup.exe file, and select Run as administrator.
  5. Select Current game, if it’s not the default option, and then select Repair Service.

There is an uninstall option once you have EasyAntiCheat_Setup.exe running as an administrator there is an uninstall button … use that.
Reboot your computer and check steam to see if the game is still running, it should not be (which was my experience)

Of course this will mean that Lost Ark will not run.
Steam will run properly and if you had noticed you will find that your task manager is reporting normal performance on CPU ID1 and also the System process will run normaly.

To play Lost Ark again you may have Steam verify the files.
