No 3D with lasts Drivers for Intel IRIS Xe Family

[alphakilo]

With the code I am developing since 5 years, D3D12 rendering disappears or DEVICE_HUNG
with recent driver 32.0.101.7085 and 7076
works with 32.0.101.5768
Microsoft D3D12 samples work correctly.
How to get intermediary drivers ?

Hello alphakilo,

Thank you for reaching out to the Intel Community Forum.

We understand that you are experiencing issues with Direct3D 12 rendering (DEVICE_HUNG / missing rendering) after updating to recent drivers, while an older version appears to work correctly. We will do our best to assist you in investigating this behavior.

To help us better analyze the issue, please provide the following details:

• Are you using a laptop or a desktop? If it is a laptop, please provide the exact model.
• What troubleshooting steps have you tried so far?
• Have you used Display Driver Uninstaller (DDU) to completely remove all residual drivers before installing a new one?
• Where did you download the driver?
• What is your reason for updating the driver? Did you encounter any issues with the previous driver version?

Additionally, to help us better understand your system configuration, please run the Intel® System Support Utility (SSU). This tool will generate a report containing your system information. You can follow the instructions provided in the Help Guide for the Intel® System Support Utility and share the generated text file with us.

If possible, we also recommend sharing:

• A minimal reproducible test case or sample of your D3D12 code (if available)
• Exact error messages or debug layer output related to the DEVICE_HUNG event

This information will greatly help us isolate the issue and determine the next steps.

If you have any questions, please let us know. Thank you.

Best regards,

Laptop ASUS Vivobook Intel  i7 X1704VA
New, bought on 11/3/2025
Windows 11 installed on 11/3/2025
With Driver Iris Xe Graphic 32.0.101.5768

More than 1 year use without any problem. I am a non professional developer of a flight simulator using DirectX /Direct3D12 11on12 (C++ Visual Studio 2026)
This code was first prepared since 2020 on an ASUS with NVIDIA Graphic card
It works also on several ASUS and HP laptop and Windosw SURFACE

What troubleshooting steps have you tried so far?
One of my friend users bought a new laptop and the defect appears on this laptop.

2D render is correct but 3D renders nothing except m_commandList1->ClearRenderTargetView(rtvHandle, couleurciel1, 0, nullptr);
3D render is correct with software adapter
I tried to find a bug in my code with Copilot and ChatGPT : 1 week of tests without result

I decided to install the last version on my laptop of development : the same problem appears.

NB: The 3D is ok with Microsoft Directx samples and version 7085.

Have you used Display Driver Uninstaller (DDU) to completely remove all residual drivers before installing a new one? No
Where did you download the driver? https://www.intel.com/content/www/us/en/support/intel-driver-support-assistant.html
What is your reason for updating the driver? Because my friend bought a new laptop and the defect appears on this laptop.

Did you encounter any issues with the previous driver version? No

You can follow the instructions provided in the Help Guide for the Intel® System Support Utility and share the generated text file with us. I have SSU, Where is this generated file ?

If possible, we also recommend sharing: A minimal reproducible test case or sample of your D3D12 code (if available) Exact error messages or debug layer output related to the DEVICE_HUNG event  I prepare it. During the work with ChatGPT or Copilot, several exceptions appears, but I corrected it. Now the only problem is : no 3D.

This information will greatly help us isolate the issue and determine the next steps.

Hello, I've prepared a simplified version of my software to test and debug functionality with the latest Intel Iris Xe drivers. It consists of two packages; how can I send them to you?
AKkaps test Iris.zip: the code (200 KB)
AKwork.zip: the active files (Assets), including the executable (56 MB) For simple execution, the AKwork folder can be located anywhere, and the executable launched from within that folder. To compile and debug the code, I use an AKwork folder located in the C:\ drive.
I've included three menu items for testing purposes:
- Landing/Takeoff, to provide two different views (but I've removed the flight dynamics)
- Day/Night - Window/Full Screen
Test with old driver is correct
Test with recent driver, no 3D
Best regards
Serge
