Frequently Asked Questions
Answers about Volume Shader BM: what it is, whether it is safe, how to read FPS, authenticity myths, GitHub questions, and the optional Android app.
Volume Shader BM is a free GPU (graphics) benchmark that runs in your browser using WebGL. It renders a demanding 3D volume-shader scene and shows live FPS so you can see how well your phone, tablet, or computer handles graphics-intensive work.
Yes. The website benchmark remains free and works in any modern browser with no install required. If you prefer a native Android experience, an optional Volume Shader app is available on Google Play. The browser test is still the primary way most people run it. See what is inside on the Volume Shader for Android page.
Not by itself. A lower-than-expected FPS can mean thermal throttling, battery saver, background apps, an older GPU, or a refurbished/modified device — among other factors. Treat the test as one performance signal, not proof that a device is counterfeit.
Volume Shader BM is a website (and optional Android app) that runs the benchmark in WebGL. There is no separate public GitHub project required to use the test — open volumeshaderbm.com and tap Run Test.
Click 'Run Test' from the homepage or navigation to open the benchmark page, then press 'Start Test'. The test measures your device's GPU performance through advanced 3D visualization with a live FPS counter.
Our Volume Shader BM test uses advanced volume shader technology to create complex 3D visualizations that provide more accurate and comprehensive performance measurements than traditional benchmark tools.
Yes, our test is designed to work across all modern devices, including PCs, smartphones, and tablets. It provides detailed insights into your device's GPU performance and overall graphical capabilities.
Lower FPS scores can be due to various factors including device specifications, browser settings, or background processes. Volume Shader BM provides detailed metrics to help identify potential performance bottlenecks.
You can record the test using screen recording and interact with the test to check you device capabilities and share the video on social media.
FPS (Frames Per Second) scores vary by device capability. Generally, 60+ FPS is excellent (smooth gaming quality), 30-60 FPS is good (acceptable for most tasks), 15-30 FPS is moderate (may struggle with demanding graphics), and below 15 FPS indicates limited GPU performance. Remember that results can vary based on device age, temperature, background apps, and browser choice.
The test runs continuously until you stop it. There's no fixed duration - you can run it for as long as you want to observe your device's performance. Most users run it for 30 seconds to a few minutes to get a good sense of their device's capabilities. You can stop the test at any time by closing the browser tab or navigating away.
You need an internet connection to initially load the website and test page. However, once the page is loaded, the test itself runs entirely in your browser using WebGL, so you could potentially run it offline if the page is already cached. For the best experience, we recommend having an active internet connection.
The test is designed to stress-test your device's GPU by rendering complex 3D visualizations. This requires significant processing power, which generates heat - this is completely normal. The test pushes your GPU to its limits to accurately measure performance. If your device becomes too hot or unresponsive, simply close the browser tab to stop the test. We recommend ensuring good ventilation and not running the test for extended periods on devices prone to overheating.
Yes, the test is safe for your device. It runs entirely in your browser and doesn't install any software or modify your device. However, because it's a stress test that pushes your GPU to its limits, it may cause your device to become warm, consume battery power, or temporarily slow down. This is normal and expected. If your device becomes too hot or unresponsive, simply close the browser tab. The test won't cause permanent damage to your device.
Volume Shader BM works with any modern browser that supports WebGL. This includes Chrome, Firefox, Safari, Edge, and Opera. Most modern browsers have WebGL enabled by default. If you're experiencing issues, make sure your browser is up to date and that WebGL is enabled in your browser settings.
Yes! Many users share their results on social media platforms like TikTok, Instagram, Twitter, and Facebook. You can compare your FPS scores and performance metrics with others. However, remember that results can vary based on device specifications, browser choice, background apps, and testing conditions. For fair comparisons, ensure similar testing conditions (same browser, similar device age, etc.).
Lag or stuttering during the test indicates that your device's GPU is struggling to render the complex 3D visualizations smoothly. This is normal for older devices or devices with lower-end GPUs. The test is designed to push your device to its limits to accurately measure performance. If the lag is severe or your device becomes unresponsive, close the browser tab to stop the test. This helps you understand your device's true performance capabilities.
No, our test does not collect or store your personal data or benchmark results. All processing happens locally in your browser using WebGL technology. Your data never leaves your device, ensuring complete privacy. We may collect basic, anonymized analytics data (like page views) through standard web analytics tools, but this doesn't include any personal information or test results.
Absolutely! Volume Shader BM is perfect for testing and comparing multiple devices. Simply run the test on each device using the same browser and similar conditions for fair comparison. Many users test multiple smartphones, tablets, or computers to compare their performance. This is especially useful when deciding which device to purchase or when comparing different models.
If the test doesn't start, first check that your browser supports WebGL. You can verify this by visiting a WebGL test website. Make sure your browser is up to date, try refreshing the page, or try a different browser. If you see an error message, it may indicate that WebGL is disabled in your browser settings or that your device doesn't support WebGL. Check your browser settings to enable WebGL, or try updating your graphics drivers.
Our test provides accurate GPU performance measurements, but results can vary based on several factors including device temperature, background applications, browser choice, and power settings. For the most accurate results, close unnecessary apps, ensure your device is cool, use performance mode (not battery saver), and run the test multiple times to average the results. The test is designed to stress-test your GPU, so it provides a good indication of your device's graphics capabilities.
While the test can't definitively identify fake devices, lower-than-expected performance compared to the same device model might indicate issues. If your device consistently scores significantly lower than expected for its model, it could suggest a fake, refurbished, or modified device. However, many factors affect performance, so use this as one indicator among others rather than definitive proof.
Yes, our test is completely free to use. There are no costs, subscriptions, or hidden fees. The web test runs entirely in your browser with no install required. You can use it as many times as you want. An optional Android app is also available on Google Play if you prefer a native experience.
