GPU / WebGL Test
Probe your browser for WebGL 1/2 support, renderer and vendor strings, and key GPU limits like max texture size, then run a live spinning cube test. Runs entirely in your browser.

How it works
- The page requests a WebGL 2.0 context first, then WebGL 1.0 as a fallback.
- If a context is created, it reads renderer, vendor, and hardware limits directly from the driver.
- An animated triangle is drawn every frame to confirm the GPU is actually rendering, not just reporting support.
- Click "Re-run test" any time — useful after toggling hardware acceleration in your browser settings.
FAQ
What does this test actually check?
It asks your browser to create a WebGL 2.0 (falling back to WebGL 1.0) rendering context, then reads back the renderer/vendor strings and hardware limits the driver reports, and draws an animated triangle so you can see GPU-accelerated frames being produced live.
Why does the renderer say "SwiftShader" or "ANGLE"?
Those are software or translation layers. SwiftShader means your GPU driver is blocked or unavailable and rendering fell back to the CPU. ANGLE is normal on Windows Chrome — it translates WebGL calls to Direct3D and still uses your real GPU.
My browser shows "WebGL is not available" — what can I do?
Check that hardware acceleration is enabled in your browser settings, update your graphics drivers, and make sure the browser isn't running in a restricted/sandboxed environment (some virtual machines and remote desktops disable GPU passthrough).
