[Arc B580] [Fortnite DX12] FPS lag causing freezes every 2 seconds

[RequeM]

I am using the latest Intel Arc graphics driver version 32.0.101.6972 with an AMD Ryzen 7 7800X3D processor.
I have Windows 11 as my operating system, and all my system drivers and the game are fully updated.
When playing Fortnite in DirectX 12 mode, the game briefly freezes every 2 seconds. The FPS drops sharply and then recovers, which severely impacts the gameplay experience.

I have tried everything to fix this issue. Fortnite does not launch at all in DirectX 11 mode.
In performance mode, the game also crashes frequently.

Is there any solution or fix for this problem?

Hi Recep66,

Thank you for posting in our Community. Stuttering and freezing every 2 seconds in Fortnite’s DirectX 12 mode is definitely a frustrating experience, especially with a fully updated system, Intel® Arc graphics, and a Ryzen 7 7800X3D setup. You've clearly done your part by keeping your drivers, OS, and game up to date. You've also noted that DirectX 11 refuses to launch and Performance Mode crashes frequently, which makes the situation even more challenging. I'd like to dig deeper into this and work with you toward a resolution. 

To assist further, could you please provide the following details:

• Is Resizable BAR enabled in your BIOS? Arc GPUs require this for optimal performance
• What is your current BIOS version and motherboard model? (Helps rule out chipset-related compatibility issues.)
• Does the freezing also happen in other games or only in Fortnite?
• Have you tested Fortnite with a clean reinstall after deleting the shader cache and saved config files?
• Had the issue happened before?
• Could you please provide CapFrameX data for this game? This will allow me to analyze performance metrics in more detail and identify any potential issues. Ideally, please share a CapFrameX file that includes at least 2-5 minutes of gameplay.

Additionally, I'd like to delve deeper and verify specifics like the graphics models, precise driver versions, and any system errors. Utilizing the Intel SSU tool will enable me to collect detailed information about your system setup, which could aid in identifying the underlying cause of this issue.

Have a nice day!

Best regards,

Thank you for your response and assistance. Below is a summary of the information you requested regarding the issue:

Resizable BAR is enabled in the BIOS. My motherboard is an ASUS Prime B650M-R running BIOS version 3014. The freezing/stuttering issue occurs exclusively in Fortnite, where the game consistently stutters every 2 seconds. Other games do not exhibit this behavior. I have already performed a clean reinstallation of Fortnite, including the manual deletion of shader cache and configuration files. This issue has been present with previous drivers and still persists with the latest 6972 driver.

Hello Recep66,

Thank you for your detailed response and for providing the additional information. I appreciate the time and effort you’ve already put into troubleshooting, especially the clean reinstall of Fortnite and the removal of shader cache and config files. That really helps narrow things down. 

I’ll need to conduct additional research on this issue and will post an update in this thread once I have more information about this matter.

Have a nice day!

Best regards,

Von M.

Dear Recep66, 

Have you since found a fix to this issue? I am facing the exact same issue and am growing weary and tiresome from it. It would offer me great resolve to know if you have found a solution to this issue or not. 

Thanks, 
Ezra

I couldn't find a solution for DX12, but it works stably in performance mode. Right now, the game crashes after a while after pressing Alt + Tab. I'm waiting for a solution from Intel's support team.

Dear RequeM, formerly Recep66, 

I am pleased to inform you that I have solved the problem with the help of the Intel Customer Support team. I will paste the instructions I was given. I have also asked the Intel Customer Support Team to send you an email in your own ticket the same instructions if you would prefer the solution instructions come from them directly. 

Thanks, 
Ezra

Intel Customer Support Team Solution:

To help address this issue, we recommend performing the following steps using the Display Driver Uninstaller (DDU) tool:

1. Download the latest version of the software.
   • If you download the Installer, run it, it will create a shortcut on the desktop. 
   • If you download the Portable/ self-extracting version, look for the executable and extract it. Remember the path. 
2. Reboot into Windows* safe mode. (Refer to Start your PC in safe mode in Windows.)
3. Look for the shortcut on the desktop (step 1.1) or the extract path chosen (step 1.2.1) and run the DDU executable.
4. Click Close in the Options window.
5. Select device type to GPU and select device to INTEL.
6. Click Clean and restart or Clean and Shutdown depending on your needs.
7. Wait for the software to finish the process and which will automatically reboot Windows to the typical mode or shutdown the system.

Once these steps are completed, please test your system again and let us know if you still experience frame rate drops. Your feedback will help us determine the next best course of action.

Hello Recep66,

I replicated the issue but I wanted to let you know that Fortnite was recently updated, and I no longer see the problem. Please try updating the game, and after doing so, monitor your system to see if the issue persists.

Hi EzraEpic, for us to address your concern and to avoid any confusion, please create a separate thread and one of the supports will be helping you.

ArchieD_Intel,

I have spent the better part of a month and a half communicating with the Intel Customer Support team. Had you actually read my replies to this thread, you would have noticed that not only have I given a possible solution to this issue, but I have also linked my own post detailing the exact same issue so that future users can refer to a more documented case of the issue. I recommend reading comments before replying to them without the necessary knowledge. I appreciate the Intel team helping the community with issues like these. 

Thanks, 
Ezra

Hello Recep66,

I just wanted to follow up. Have you had a chance to review my previous response? Please let me know if you still need any assistance; I’m here to help. As mentioned, we were able to replicate the issue on our end. However, since Fortnite’s recent update, we no longer see the problem occurring. Could you please try updating the game and then monitor your system to confirm if the issue persists? Additionally, have you had a chance to check out @EzraEpic's  response with the troubleshooting steps he shared? If so, I’d love to hear how that went for you.

@EzraEpic , I sincerely apologize for any confusion caused earlier by my colleague, @ArchieD_Intel . I truly appreciate the time you took to share the solution provided by our Intel Customer Support team. I also reviewed the link you mentioned, and I’m glad to see that the issue was successfully resolved by downloading and installing the latest version of the software, rebooting into Safe Mode, and allowing the process to complete, which then automatically restarts Windows in normal mode (or powers down the system). We value your patience and collaboration throughout this process, and your feedback helps us continue improving our support experience. Please don’t hesitate to reach out if you encounter any further issues, we’re always here to help

Hello Recep66,

I have not heard back from you, so I will close this inquiry now. If you need further assistance, please submit a new question as this thread will no longer be monitored.

@EzraEpic, thanks for sharing your detailed findings. This does look driver-related with the Arc B580. Since this thread has been open for over 30 days, we ask other members with similar issues to start a new thread so we can provide more focused support. We’ll keep monitoring driver updates for improvements on stuttering.

Best regards,
