Understanding Your Volume Shader Benchmark Results

Learn what your volume shader benchmark metrics mean and how to interpret GPU stress test performance data.

FPS (Frames Per Second)

Higher is better

Measures how many frames your GPU can render during the volume shader test. 60+ FPS indicates smooth ray marching performance, while lower values show hardware limits under heavy GPU benchmark load.

Frame Time (ms)

Lower is better

Time taken to render a single volume shader frame in milliseconds. Under 16.7ms needed for 60 FPS; under 33.3ms for 30 FPS. High frame times indicate GPU stress test bottlenecks.

Min/Max FPS (Stability)

Closer together is better

The range between your lowest and highest FPS during the volume shader benchmark. A narrow gap indicates stable GPU performance. Wide gaps may suggest thermal throttling during ray marching.

💡 Volume Shader Benchmarking Tips

  • •Close other applications to free GPU resources for accurate ray marching benchmark results
  • •Run the GPU stress test multiple times—initial runs may be slower due to volume shader compilation
  • •Compare GPU benchmark results using the same preset to ensure fair comparison

Why Use the Volume Shader Benchmark?

Understand the technology behind our GPU stress test and why volume shader rendering is the ultimate measure of graphics performance.

Volumetric 3D fractal rendering demonstrating volume shader technology

What is a Volume Shader?

A volume shader is a specialized rendering technique that simulates how light interacts with semi-transparent, three-dimensional materials like fog, smoke, clouds, and fire. Unlike surface shaders that only calculate color at object boundaries, volume shaders use ray marching algorithms to sample density and lighting throughout a 3D space.

This makes volume shader rendering extremely GPU-intensive, as the graphics card must perform thousands of calculations for every pixel on screen. That's why our volume shader benchmark provides such an accurate measure of your GPU's real-world performance—it tests the same rendering techniques used in modern games and professional 3D applications.

Frequently Asked Questions about
Volume Shader

Common questions about our volume shader GPU benchmark and troubleshooting tips.

Low frame rates during the volume shader benchmark are completely normal—that's actually what we're measuring! The test is designed to push your GPU to its limits by rendering complex volumetric 3D fractals. Lower FPS simply indicates your GPU's maximum sustainable performance under heavy load. Compare your results on the leaderboard to see if your score is typical for your graphics card model.
This is a common issue on laptops and systems with both integrated and dedicated graphics. Browsers often default to the power-efficient integrated GPU. To fix this: • Windows: Go to Settings → Display → Graphics, add your browser, and select "High Performance" • NVIDIA: Open NVIDIA Control Panel → Manage 3D Settings → Add your browser → Select "High-performance NVIDIA processor" • AMD: Open Radeon Settings → Gaming → Add your browser → Set Graphics Profile to "High Performance" • Chrome: Visit chrome://gpu to verify which GPU is being used
Ray marching is the core algorithm behind volume shader rendering. Unlike traditional rendering that calculates color at surface intersection points, ray marching "steps" along each viewing ray, sampling the volume at regular intervals. At each step, it accumulates color, density, and lighting information. This iterative process creates realistic volumetric effects like fog, clouds, and smoke, but requires significant GPU processing power—which is why volume shader benchmarks are excellent stress tests.
Our volume shader benchmark provides a real-world measure of GPU performance for graphics-intensive workloads. Unlike synthetic benchmarks that test isolated features, we stress multiple aspects simultaneously: shader core utilization, memory bandwidth, cache efficiency, and thermal behavior. While no single benchmark tells the whole story, our results correlate well with performance in modern games and 3D applications that use volumetric effects.
Yes! Our volume shader test is fully browser-based and works on any device with a modern web browser that supports WebGL 2.0. Mobile GPUs will naturally score lower than desktop graphics cards, but you can still compare your mobile device against others in our mobile-specific leaderboard category. Note that running the benchmark may cause your device to heat up—this is normal for GPU stress tests.
The three modes control the intensity of the volume shader stress test: • Lite: Lower resolution and fewer ray marching steps. Good for older or mobile GPUs. • Standard: Balanced settings for typical desktop graphics cards. Recommended for most users. • Inferno: Maximum quality with highest ray marching iterations. Only for high-end GPUs. Will cause significant heating and may trigger thermal throttling on less capable systems. Your score is adjusted based on the mode, so Inferno results are weighted higher on the leaderboard.
VolumeShader_BM is the name this browser-based GPU stress test goes by. It renders a heavy volumetric ray-marching scene to measure your GPU's sustained performance, and it went viral because phones produce unusually low frame rates. You'll also see it written as volume shader bm, volumeshader bm, or vsbm. You can run it right here on this page — no app, no install.
Yes. The test runs entirely in your browser and collects no personal data. We don't gather IP addresses, location, accounts, or any personally identifiable information — benchmark submission is voluntary and anonymous. The only data involved is your GPU model and the benchmark metrics themselves, which stay on your device unless you choose to submit.
Yes — it runs in any modern mobile browser (Chrome, Safari, Edge) on Android and iPhone, including Snapdragon 8-series and other flagship chips. Mobile GPUs score lower than desktops by design; that's the measurement, not a problem. Pick a lighter preset (Lite or Balanced) on phones for a stable run.
