Volume Shader BM is a free, browser-based GPU benchmark that measures graphics card performance through volumetric shader rendering, providing real-time FPS and rendering metrics for developers, gamers, and researchers.
What is Volume Shader BM?
Volume Shader BM is a WebGL 2.0 benchmark tool that evaluates GPU performance by rendering complex three-dimensional volumetric data in real time. It takes a compatible browser as input and produces frame-rate measurements, rendering time breakdowns, and an overall volume shader score. The benchmark runs entirely in-browser (no download required) and is developed by the Volume Shader team.
Key Features
- Real-time FPS tracking — Live frame rate counter and performance metrics displayed during benchmark execution, updated every frame.
- WebGL 2.0-based — No installation needed; runs in any WebGL 2.0 compatible browser on desktops, laptops, and mobile devices.
- Cross-platform compatibility — Works on Windows, macOS, Linux, Android, and iOS as long as the browser supports WebGL 2.0.
- Fractal volume rendering — Tests GPU ability to compute iterative mathematical fractals using ray marching algorithms, simulating scientific visualization workloads.
- Ray marching performance test — Evaluates density sampling, opacity accumulation, and lighting calculations for cloud and atmosphere rendering.
- Shader compilation speed measurement — Tracks how quickly the system compiles and optimizes complex volume shaders, important for development workflows.
Who is it for?
- Game developers — Assess how well a GPU handles modern volumetric effects (fog, clouds, smoke) before setting performance targets for their titles.
- PC gamers — Verify system readiness for games with advanced atmospheric rendering by comparing benchmark scores to known GPU thresholds.
- Scientific researchers — Evaluate GPU suitability for medical imaging, fluid dynamics, or astronomical data visualization tasks that rely on volumetric shaders.
What can you do with Volume Shader BM?
- Benchmark your GPU: Click Start Benchmark Test to run the automatic test suite through fractal and ray marching scenarios, then review detailed FPS and frame-time graphs.
- Compare across devices: Use the same Launch Volume Shader BM Test link on different machines to generate comparable performance data for hardware purchasing decisions.
- Identify thermal throttle: The performance-over-time graph in results helps detect FPS drops caused by overheating or power limits during sustained volumetric rendering.
How does Volume Shader BM work?
The benchmark runs three phases automatically. First, it detects your GPU and initializes WebGL volumetric data structures. Then it executes multiple rendering scenarios (fractal volume, ray marching, shader compilation) while collecting real-time metrics. Finally, it compiles frame rates, rendering times, and quality data into a detailed report with graphs showing performance over time.
Pricing
Volume Shader BM is completely free to use. No account, payment, or registration is required.
FAQ
What makes Volume Shader BM different from other benchmarks?
It focuses exclusively on volumetric shader performance using ray marching algorithms and density sampling—workloads that directly reflect modern game and scientific visualization demands, unlike older polygon-centric benchmarks.
How accurate are Volume Shader BM results?
Results are reproducible under consistent thermal conditions. The benchmark uses fixed rendering parameters and controls for GPU throttling by tracking frame-time variance. Scores correlate with real-world volumetric rendering performance in professional applications.
