Frequently Asked Questions

A GPU stress test is a diagnostic tool that evaluates your graphics card's performance and stability under heavy load. It helps identify potential issues, measure overall performance, and ensure your GPU can handle demanding tasks like gaming or content creation.

Stress testing helps verify stability after overclocking, identify potential hardware issues, ensure your GPU can handle demanding applications, and establish a performance baseline for comparison over time.

Yes, our browser-based tests are completely safe. They operate within browser security limitations and can't access hardware controls. Modern GPUs have built-in thermal protection that prevents damage from overheating.

No! All our tests run directly in your web browser using WebGL technology. No downloads, installations, or plugins required.

It depends on your goal. For general performance, start with the 3D Rendering Test. For physics-heavy games, try the Particle System Test. For visual quality, the Shader Test is best. We recommend running all tests for a complete picture.

We recommend 1-5 minutes per test for meaningful results. Longer tests (5+ minutes) can reveal stability issues that shorter tests might miss.

Our tests work on all modern browsers including Chrome, Firefox, Edge, Safari, and Opera. For best results, use the latest version of your preferred browser.

Absolutely! Our tests are fully responsive and work on iOS and Android devices with WebGL support. Performance will vary based on your device's GPU capabilities.

Fullscreen mode runs the test at your display's full resolution, providing more accurate results for how your GPU performs in actual gaming or application scenarios.

60 FPS or higher is generally considered good for smooth performance. 30 FPS is the minimum for playable experiences. The higher your FPS and the more stable (low variance), the better your GPU performance.

Our performance score (0-100) combines FPS, stability, frame time consistency, and visual quality. 90-100 is Excellent, 75-89 is Very Good, 60-74 is Good, 40-59 is Fair, and below 40 is Poor.

Stability measures how consistent your frame times are. 95%+ means very stable performance with minimal stuttering. Lower stability indicates frame time spikes that can cause visible stuttering.

Results can vary due to background processes, browser tabs, thermal conditions, and driver states. For consistent results, close other applications and run tests multiple times.

You can export your results and share them manually. However, direct comparisons should account for different settings, browsers, and test durations.

WebGL (Web Graphics Library) is a JavaScript API for rendering 3D graphics in web browsers without plugins. It's based on OpenGL ES and is supported by all modern browsers.

WebGPU is a modern graphics API that provides access to GPU compute capabilities and more efficient rendering than WebGL. It is currently supported in Chrome, Edge, and experimental Firefox builds.

Browser security restrictions prevent websites from accessing hardware sensors like temperature monitors. For temperature monitoring, use desktop software like MSI Afterburner or HWiNFO.

Our tests are designed to stress the GPU. However, some physics calculations in the Particle Test use JavaScript (CPU). The rendering itself is GPU-accelerated via WebGL/WebGPU.

This usually means your browser has WebGL disabled or your GPU drivers need updating. Try updating your graphics drivers, enabling hardware acceleration in browser settings, or using a different browser.

This can happen with unstable GPU drivers or hardware issues. Try updating your graphics drivers, reducing test complexity settings, or using a different browser. If crashes persist, it may indicate a hardware problem.

Check that no other tabs or applications are using significant resources. Ensure your laptop is plugged in (battery mode may throttle GPU). Also verify you're not thermally throttling from previous heavy usage.

This usually indicates a WebGL initialization failure. Try refreshing the page, disabling browser extensions, or updating your GPU drivers.
