Arc B580 cannot run properly when using D5 Render software and the CPU usage reaches 100%

When using D5 Render software, it cannot run normally and the CPU usage reaches 100%

Hi, Sofia96.

Thank you for posting in our Community. The Arc B580 should offload significant rendering tasks from the CPU to the GPU. A full 100% CPU utilization suggests either, D5 Render is not detecting or properly leveraging the GPU, or there may be a driver or compatibility issue between the app and Arc graphics. Or system resource contention is causing a fallback to software-based rendering.

 To better assess the situation and identify any hardware/software compatibility or optimization gaps, I’d like to gather additional information:

• Is CPU usage hitting 100% during launch, during active rendering, or during idle use of D5 Render? Does the system become unresponsive, crash, or simply perform slowly?
• What is the GPU usage (Arc B580) during this workload? Is the rendering engine in D5 set to GPU or CPU mode (if configurable)

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. For your privacy and security, I have already sent you an email to collect the SSU reports. Once I receive the logs, I can investigate further and provide better assistance.

Have a nice day!
