What is it?

A GPU (Graphics Processing Unit) handles the rendering of images, video, and 3D graphics. This tool uses the WebGL debugging API to ask your browser for the unmasked vendor and renderer strings of the graphics hardware currently processing this page.

Why this matters

Complex web applications like 3D games, Google Maps, and browser-based design tools rely heavily on hardware acceleration. If your GPU is outdated or your drivers are crashing, these applications will fallback to slow software rendering.

Practical Use Cases

  • Users trying to quickly find their graphics card model without digging through the Windows Device Manager.
  • Developers diagnosing performance issues in Three.js or WebGL applications for specific graphics hardware.
  • Troubleshooting why a browser game is lagging or crashing.

Troubleshooting

Renderer shows SwiftShader, Mesa, or software rendering

Hardware acceleration is disabled or your graphics drivers are corrupted. Enable hardware acceleration in your browser settings and update your GPU drivers.

It shows my integrated graphics instead of my dedicated GPU

Browsers often use low-power integrated graphics (like Intel UHD) to save battery. To force your dedicated GPU (like NVIDIA), adjust your OS graphics settings for your specific browser.

Frequently asked questions

How do I check my GPU online?

Load this tool and we will extract the WebGL renderer string from your browser, which typically contains your exact graphics card model.

Is this my dedicated or integrated GPU?

It displays whichever GPU your browser is currently utilizing. On laptops with dual graphics, this is often the integrated, lower-power chip.
