Question 1

What is Volume Shader BM?

Accepted Answer

Volume Shader BM (Benchmark) is a free, browser-based GPU performance test that uses WebGL 3D volume rendering to measure your graphics card capabilities. BM stands for 'benchmark' which evaluates GPU performance by rendering complex volumetric fractals using WebGL technology. It provides FPS metrics, frame times, and GPU utilization data completely in-browser without installation.

Question 2

Does Volume Shader run on CPU or GPU?

Accepted Answer

Volume Shader BM runs exclusively on your GPU using WebGL fragment shaders that execute directly on the graphics card's parallel processing cores. While the CPU handles basic coordination and input, all intensive rendering computations happen on the GPU, making it an accurate GPU performance test.

Question 3

How to make Volume Shader BM fast?

Accepted Answer

To make Volume Shader BM run faster: 1) Start with 'Ultra Low' or 'Low' preset, 2) Reduce Kernel Iterations (controls detail), 3) Increase Step Size (sampling stride), 4) Lower Resolution Scale to improve FPS, 5) Close GPU-intensive apps and browser tabs, 6) Update GPU drivers, 7) Use high-performance power mode for laptops.

Question 4

How to make Volume Shader no lag?

Accepted Answer

To eliminate lag in Volume Shader: 1) Select Ultra Low or Low preset, 2) Reduce Kernel Iterations to 2-4, 3) Increase Step Size to 0.004-0.008, 4) Lower Resolution Scale to 0.25-0.75, 5) Close background applications, 6) Update graphics drivers, 7) Enable hardware acceleration in browser. Aim for stable 30+ FPS for smooth performance.

Question 5

What's the difference between GPU and CPU rendering?

Accepted Answer

GPU rendering uses parallel processing across thousands of cores for graphics workloads, making it 10-100x faster for shader-based tasks like volume rendering. CPU rendering uses fewer, more powerful cores for sequential tasks. Volume Shader exclusively uses GPU rendering because volumetric ray marching requires massive parallel computation.

Question 6

Why does my GPU get hot during the benchmark?

Accepted Answer

Volume Shader BM intentionally stress-tests your GPU by rendering complex 3D fractals, pushing your graphics card to high capacity. This intensive rendering generates heat as the GPU processes millions of calculations per second. This is normal and safe - modern GPUs have built-in thermal protection that throttles performance if temperatures become unsafe.

Question 7

How accurate is the Volume Shader benchmark?

Accepted Answer

Volume Shader provides accurate GPU performance metrics for WebGL workloads, measuring real-time frame rates and render times. However, results vary based on browser efficiency, driver versions, and background processes. For consistent benchmarking, use the same preset across devices, close background apps, and run multiple tests.

Question 8

What browsers are supported?

Accepted Answer

Volume Shader works in modern browsers that support WebGL, including Chrome (recommended), Firefox, Safari, and Edge. All require WebGL 1.0 support and hardware acceleration enabled.
