# What is Hardware testing?

> D5 Render is based on real-time ray-tracing technology and has minimum requirements for hardware and system configurations.

When D5 Render is opened for the first time, it automatically checks if the user's device meets the operating requirements. If the device does not meet the current configuration requirements, relevant information will be displayed.

If you need to test again, you can click the version number at the bottom left corner of D5 Launcher or Menu-Help-System Info, and it will re-test when you open it again.
