Comprehensive WebGL and GPU testing tool that displays GPU information, WebGL version, supported extensions, and 3D rendering capabilities. Test shader performance, texture support, and verify hardware acceleration. Essential for game developers and 3D web app creators.
WebGL uses your device's GPU (Graphics Processing Unit) to render 3D graphics directly in the browser, achieving performance comparable to native applications. Modern GPUs can process billions of pixels per second, enabling complex 3D scenes, realistic lighting, and advanced visual effects. This tester reveals your GPU's actual capabilities and WebGL support level.
Start with the live tester below. Supporting details, FAQs, and troubleshooting guidance are placed after the tool so the main action is easier to find and use immediately.
Test WebGL support, GPU information, and 3D rendering performance.
Common problems
If the live tester does not behave as expected, these are the first checks most users should try before assuming the hardware is broken.
Check WebGL version - WebGL 1.0 vs 2.0 support
Verify GPU information - see your graphics card details
Test supported extensions - advanced features available
Check hardware acceleration - ensure GPU is being used

Test your keyboard input, detect dead keys, and verify all keys are working correctly.
Test mouse buttons, scroll wheel, pointer tracking, and touch input.
Test your microphone input levels in real-time. Verify microphone is working.
Test your speakers or headphones with reference tones.
Helpful questions
Use these answers to understand results, browser limitations, permissions, and sensible next troubleshooting steps.
Open the live webgl & gpu test on this page and follow the prompts shown in the tester area. The tool runs directly in your browser, so you can check your device without installing additional desktop software or signing in.
Check browser permissions, confirm the device or browser feature is enabled, and reload the page if needed. Many browser-based testers depend on permission prompts, secure context support, or hardware access that must be approved before the test can run fully.
Game development - verify WebGL support and performance. It can help you confirm whether the issue is caused by the hardware itself, a browser permission setting, or a system configuration problem before you spend more time debugging.
