Performance Issue Details:

1.The framerate was noticeably lower throughout the entire game compared to Win24H2, as I had frame rate monitoring software running for comparison.

2.The game runs with more stable framerates on Windows 11 24H2, with no noticeable stuttering.

3.Timeline:Updated to the Intel ARC graphics driver version 8132.

 · Windows 11 25H2 update

 · Updated the Intel ARC graphics driver to version 8132.

 · Used DDU to remove the 8132 driver.

 · Performed a clean installation of the 8135 driver.

 · Opened the game and started playing.

Driver Testing:

1.I am currently using the 8135 driver.

2.DDU has been used.

In the snow scene of the Gloriana map during gameplay, there are occasional brief image flickering, but it recovers immediately. Additionally, after enabling ray tracing in Darktide, the VRAM usage continuously rises until it reaches full capacity. I am unsure what is causing these issues and can only request a thorough investigation. Thank you for your assistance.

Hi 你真的无敌了,

Thank you for providing the detailed information and SSU report. Your testing methodology is excellent, using frame rate monitoring software to compare performance between Windows 11 24H2 and 25H2 gives us concrete evidence of the performance degradation.

I can see you've performed thorough troubleshooting, including DDU clean installations of both driver versions 8132 and 8135, which covers all the standard steps comprehensively.

To help with a more comprehensive investigation, could you also provide:

1. CapFrameX Data: Please capture approximately 5 minutes of gameplay showing the performance issues you're experiencing
2. Graphics Settings: Screenshots or details of your current Warhammer 40K: Darktide graphics settings configuration

Hi 你真的无敌了,

Thank you for providing the comprehensive information, English screenshots of your graphics settings, and the CapFrameX performance data. I can see that you've done excellent testing comparing performance between Windows 11 24H2 and 25H2, and your systematic approach using frame rate monitoring software provides clear evidence of the performance degradation.

I will be checking this internally and will get back to you once I have more information available. The combination of your SSU report, CapFrameX data, and detailed testing methodology will be very helpful for the investigation.

Best regards,

Hi 你真的无敌了,

Before I investigate this internally, I'd like you to try the latest Intel Arc driver version 32.0.101.8136, which has just been released and may contain specific optimizations.

Please download and install the latest driver using DDU for a clean installation:

• Driver download: https://www.intel.com/content/www/us/en/download/785597/intel-arc-graphics-windows.html
• Use DDU to completely remove the current driver first
• Install the new 32.0.101.8136 driver

Test Warhammer 40K: Darktide performance again

After testing with the new driver, please let me know if you still experience the same performance issues, VRAM problems with ray tracing, and image flickering. If the issues persist, I will then check this internally for further investigation.

Best regards,

Dean R.

I have followed the process to replace the driver of 8136. After my testing, the performance issue still exists. The VRAM keeps increasing after playing for a long time with ray tracing on. However, I didn't find any flickering when I ran through the map. If possible, please handle the performance and VRAM issues. Thank you again for your help.

[DeancR_Intel]

Hi 你真的无敌了,

Thank you for testing the latest driver version 32.0.101.8136 and providing the updated CapFrameX data. I appreciate your thorough testing and for confirming that while the flickering issue appears to be resolved, the performance degradation and VRAM issues with ray tracing still persist.

I will be checking this internally and will get back to you once I have more information available regarding the remaining performance and VRAM issues you're experiencing with Warhammer 40K: Darktide on your Intel Arc B580.

Thank you for your patience and continued cooperation with the testing process.

Hi 你真的无敌了,

Thank you for your detailed report regarding the performance degradation you're experiencing with your Intel Arc B580 in Warhammer 40K: Darktide after upgrading to Windows 11 25H2.

I've reviewed your comprehensive testing with multiple driver versions (8132, 8135, 8136) and the DDU clean installations you've performed. To help us further investigate this Windows 11 25H2 compatibility issue, I need you to test one additional driver version.

Please try the following:

• Test Driver Version 32.0.101.6874 Intel® Arc™ Graphics - Windows*:
  • Perform a DDU clean installation
  • Install driver version 32.0.101.6874
  • Test Warhammer 40K: Darktide performance
  • Record CapFrameX data for comparison
• Provide Comprehensive CapFrameX Data:
  • CapFrameX results from driver 32.0.101.6874 (if available)
  • CapFrameX results from the latest driver 32.0.101.8136
  • Any previous CapFrameX data you have from Windows 11 24H2 for comparison

Once you complete this testing and provide the CapFrameX performance data comparing the older driver (6874) with the newest driver (8136), I'll check this inquiry for further analysis of the Windows 11 25H2 performance regression issue.

This additional data will help us better understand the performance differences and VRAM management issues you're experiencing with ray tracing enabled.

Best regards,

Dean R.

I'm very sorry that I can't provide the CapFrameX data for 24 hours. As I have a newly installed system, the previous monitoring software I used was a comprehensive statistics software for frame rate calculation, so I can't provide it. When I tried to reproduce the system, I couldn't find the Windows version from the Microsoft official website. There's no other way. But I hope the new test file I'm providing now can be helpful for performance optimization.

[你真的无敌了]

There is an error with the translation software, and I am unable to provide the CapFrameX data for win24h2.

[你真的无敌了]

There are some errors in the file names, though the driver is indeed 6874.

[DeancR_Intel]

Hi 你真的无敌了,

Thank you for providing the CapFrameX data in the 25h2.7z file and for testing driver version 32.0.101.6874 as requested. I understand that you're unable to provide the Windows 11 24H2 CapFrameX data since you have a newly installed system and can't locate the previous Windows version from Microsoft's official website.

I've received your test files and note that while there may be some errors in the file names, you've confirmed that the driver version 6874 was indeed tested. This data will still be valuable for our analysis.

Even without the Windows 11 24H2 comparison data, the performance comparison between the older driver (6874) and the newest driver (8136) on Windows 11 25H2 will help us analyze the performance regression and VRAM management issues you're experiencing with ray tracing in Warhammer 40K: Darktide.

I will be checking this internally and will get back to you once I have more information about the Windows 11 25H2 compatibility analysis.

Hi 你真的无敌了,

Thank you for your patience as I continue investigating the performance degradation you're experiencing with your Intel Arc B580 in Warhammer 40K: Darktide after upgrading to Windows 11 25H2.

I appreciate the comprehensive testing you've completed, including DDU clean installations of driver versions 8132, 8135, 8136, and 6874, along with the CapFrameX performance data you've provided comparing driver versions on Windows 11 25H2.

I've been analyzing your case and have conducted additional testing using Intel Arc B580 on both Windows 11 24H2 and 25H2. During my testing, I found that the Arc B580 is performing at comparable levels to competitor graphics cards across both Windows versions.

To help me better understand the specific VRAM usage issue you're experiencing with ray tracing enabled, could you please provide the following information:

How long does it typically take for the VRAM leak to reach full capacity when ray tracing is enabled?

This timing information will help me reproduce the exact conditions you're experiencing and provide more targeted analysis of the VRAM management behavior.

Please test this in your typical gaming scenario with ray tracing enabled and let me know approximately how many minutes of gameplay it takes before you notice the VRAM reaching maximum capacity.

Thank you for your continued cooperation in helping me resolve this issue.

Best regards,

Thank you for your help. After my tests, I found that the video memory would be full after playing for 3 to 4 hours in Havoc40 mode. Especially when opening the backpack weapon depot or the weapon store, the video memory would increase. It would drop again after exiting.
