Problems with Arc 730m

[TonyEng]

I recently bought a system with an Arc 730m GPU.  From what I have read it should support Directx 12 Ultimate.  However, when I view the system capabilities it shows that the Shader Model is version 5.1 and not 6 using Vulkan.  

The second issues is the Arc control app does not have a button to configure the performance of the card.  There is just an empty space where the button should be. 

My system has an Intel® Core™ i7-12650H Processor, 10 Cores/16 Threads
(24M Cache, up to 4.7 GHz) with 32gb of memory running Windows 11 Professional. 

Thanks for any help in advance.

Hello TonyEng,

Thank you for posting on the Intel®️ communities. To understand the issue in a better way about the version while using Vulkan with your Intel® Arc™ A730M Graphics, please answer the following questions :

• What software are you using to check the Shader Model version?

I also see that you reported a different issue related to Intel® Arc™ Control, please open another thread related to it, to keep this one organized and to help you in the best way.

Hi Andres,

Thank you for your response.  I am using the System Info/Capabilities menu on Arc Control.  I am also using Directx Caps Viewer.  I have attached screenshots of both programs. 

Something noteworthy,  I am using Unreal Engine 5.3.  It was working well when I first installed it.  I cannot be 100% sure about this, but it seems after I upgraded the Intel graphics driver to beta, I started getting an error message in Unreal Engine stating that shader model 6 was not supported. My uncertainty comes from this PC system being new and I have conducted several changes to the software before investigating this issue.

Hello TonyEng,

Thank you for the explanation and clarification.

Please provide the information below before we start with the troubleshooting steps:

• You mentioned when you start Unreal Engine, you receive the error message that the Shader Model 6 was not supported. To be able to see the error message can you take a screenshot of it?
• You also mentioned it seems the issue started after a graphics driver update, did you know what was the graphics driver version when Unreal Engine was working fine?
• To know your hardware and software information, run and attach the report for the following tool Intel® System Support Utility for Windows (SSU), you can find the steps on the link How to get the Intel® System Support Utility Logs on Windows.

Hi Andres,

Please find attached the SSU and screenshot as requested.

I haven't changed the Unreal Engine version it has always been 5.3.2.

Let me know if you have any other questions. Thanks

Hello TonyEng

Thank you for the information. Based on the log file you shared the driver version installed on the system is outdated, please let's uninstall the current version using Display Driver Uninstaller, once uninstalled please download and update to the latest version 31.0.101.4972.

Best Regards,

Hi Hugo,

I just wanted to let you know that I followed your instructions. It seems to have worked.  The Arc Control Center still says it is using shader model 5.1, but Unreal Engine says shader model 6 is supported and it doesn't produce an error any longer.  I am happy with this result. I already have another open issue posting with the Arc Control Center. Hopefully, these issues can be resolved there.

Thanks for your help.
