What is the GLview SDK?

The open-source glview-kit on GitHub lets developers integrate and trigger GLview’s rendering tests programmatically, without launching the full application. Useful for automated testing pipelines.

How do I submit my GPU data to the database?

Within GLview, the Submit function sends your GPU’s capabilities data anonymously to the centralized database. This keeps the renderer database up to date for the entire community.
