Fortnite Anti-Cheat crashes the game when it detects Intel Drivers if running on DirectX11

[djmrFunnyMan]

When trying to run Fortnite on DirectX11 with an Intel card the anticheat will crash the game due to the intel driver being "untrusted" 

I have already ran DDU but it did not resolve the issue.

Reproduction Steps: 
- Set "Rendering Mode" to DirectX11 in Fortnite settings
- Restart the game
- Queue for a Battle Royale match

You'll crash while connecting to the server.


I'm attaching the crash logs (zipped) and an SSU log of my device.

Hi @djmrFunnyMan,

You may follow the instructions provided in this article-Easy Anti-Cheat (EAC) error: Untrusted system file - Epic Games Store Support. In my opinion, it is best to get in touch with technical support for Fortnite. Based on the article, you may need to follow certain steps provided by Microsoft. Additionally, try running the launcher as an administrator, reboot the system, and test the game.

I already followed that article before I made this report. I also used DDU to cleanly reinstall the Intel drivers.
I'm making this report here, because it's specifically an Intel driver related dll that's being detected. I will also contact Epic Games support but I believe it'd be faster for Intel to resolve this issue with them.

The issue went away after reinstalling the game.

The issue was only temporarily solved by reinstalling the game. It came back after a few hours of playtime.

Hi @djmrFunnyMan,

Can we try this version. Please go ahead and install the driver version 32.0.101.6647. Let me know how it goes, please do not forget to DDU. Looking forward to your response.

I did not try your version because the issue once again stopped occuring. I'll try this when the issue starts happening again

Hi. I am also having the exact same problem, and tried using these drivers (6647) instead of the latest ones (6881).

The issue still persists and is not fixed. What else can be done?

[RandyT_Intel]

@Mqp10 for the meantime you may follow this thread, I will post an update here once I completed my analysis, thank you for your patience.

[Mqp10]

Alright thank you. Hopefully you can find a fix.

Hi @djmrFunnyMan,

Thank you for the update. Does this mean the issue is resolved? Please let me know if you still need further assistance or if it's okay to temporarily close this ticket for now. Remember, you can always submit another ticket if you need further help in the future.

Well it just means the issue happens intermittently so I can't reproduce it consistently.
I found other intel arc users have run into the same issue: https://www.reddit.com/r/FortNiteBR/comments/1lbj09o/fortnite_crash_untrusted_file_by_eac/

Hi @djmrFunnyMan,

I will begin investigating the issue and attempt to replicate it on our end. I'll post an update here or notify you directly once there are any developments. If I need further details, I'll reach out to you here. I appreciate your patience as I work on this matter.

I would like to add this is the ONLY current solution. 

Open Epic Games Launcher > Library > Three Dots (...) Next to Fortnite > Manage > Enable Launcher Options > Type -d3d12
This forces the game to run DirectX12 which won't crash, but the performance is utterly horrible and not the same as performance mode which gives me consistent 144 FPS. Even with low settings, it is not consistent.

[djmrFunnyMan]

Well yes I've been using DirectX12 because it just has way better performance than DirectX11. 
I ran into this issue when I tried testing DirectX11 performance out of curiosity

[teep77]

I just wanted to use performance mode since my frames were more smoother there.

[RandyT_Intel]

Thank you for sharing your recommendation @teep77 .

@djmrFunnyMan, you may try following these suggestions while we continue investigating the issue. Please note that while this approach may work, we are also testing the performance as mentioned by @teep77 .

[Pauete]

how the next updaate will be? it will be resolved?

[Pauete]

and when??

[teep77]

Probably for a long time so yeah people who didn’t look on the internet are cooked and also epic is prob going on summer break so maybe give it 2-3 months

Hello all,

This has been informed to the driver development team. As soon as I have news, I'll be sharing them here.
