Question 1

What is Volume Shader BM Test?

Accepted Answer

Volume Shader BM Test is a free browser benchmark that renders a volume shader with WebGL 1.0 at a fixed 1024 × 1024 resolution. The display shows current, average, minimum and maximum sampled FPS, measured frames, elapsed test time and milliseconds per frame.

Question 2

How do I start the benchmark?

Accepted Answer

Start runs the default shader at 1024 × 1024; Stop ends the run. Starting again clears the metrics, and Restart resets the benchmark. A hidden browser tab stops the test.

Question 3

Is Volume Shader BM Test free to use?

Accepted Answer

Volume Shader BM Test is a free browser benchmark that renders a volume shader with WebGL 1.0 at a fixed 1024 × 1024 resolution. No installation or account is required. Browser, operating system and available GPU information are read in your browser to describe the test environment.

Question 4

Do I need to create an account?

Accepted Answer

No account is required to use Volume Shader BM Test. You can run the benchmark immediately without any registration or sign-up process.

Question 5

What devices are compatible with the benchmark?

Accepted Answer

A browser with working WebGL is required. Driver support, hardware acceleration and browser restrictions can affect availability and results; if WebGL is unavailable, the page displays a message. You can try the test on WebGL-capable phones and tablets. The canvas supports pointer or touch dragging. Device and browser limits still affect the result.

Question 6

Which browsers are supported?

Accepted Answer

A browser with working WebGL is required. Driver support, hardware acceleration and browser restrictions can affect availability and results; if WebGL is unavailable, the page displays a message. For comparisons, keep the shader, resolution, browser, refresh-rate limit, power settings and background load similar. Results from different environments are not interchangeable hardware scores.

Question 7

Can I run the benchmark on mobile devices?

Accepted Answer

You can try the test on WebGL-capable phones and tablets. The canvas supports pointer or touch dragging. Device and browser limits still affect the result.

Question 8

Does it work on integrated graphics?

Accepted Answer

Integrated graphics can run the test when WebGL is available. Record the detected renderer; results also depend on browser settings and the test environment.

Question 9

What does FPS mean in the results?

Accepted Answer

The display shows current, average, minimum and maximum sampled FPS, measured frames, elapsed test time and milliseconds per frame.

Question 10

What is frame time and why does it matter?

Accepted Answer

Milliseconds per frame is calculated from the elapsed time and frame count of a sampling window. It describes that window's average, not the duration of every individual frame.

Question 11

What do minimum and maximum FPS mean?

Accepted Answer

FPS is sampled over windows of about 500 ms. Minimum and maximum refer to these windows; average FPS uses total measured frames and elapsed time. These are not individual frame traces or 1% low values.

Question 12

How should I compare FPS results?

Accepted Answer

For comparisons, keep the shader, resolution, browser, refresh-rate limit, power settings and background load similar. Results from different environments are not interchangeable hardware scores.

Question 13

How do I start, stop or restart a test?

Accepted Answer

Start runs the default shader at 1024 × 1024; Stop ends the run. Starting again clears the metrics, and Restart resets the benchmark. A hidden browser tab stops the test.

Question 14

Which metrics does the benchmark show?

Accepted Answer

The display shows current, average, minimum and maximum sampled FPS, measured frames, elapsed test time and milliseconds per frame.

Question 15

How do I download my results?

Accepted Answer

After measuring, use CSV or JSON to download a result snapshot, including browser, operating system, GPU information and metrics. The download is generated locally.

Question 16

What can I change in the shader editor?

Accepted Answer

The GLSL editor changes the kernel only when Apply is selected. Reset restores the default shader. Compilation errors appear on the page; this screen has no resolution, complexity-level or duration settings.

Question 17

Why is my FPS lower than expected?

Accepted Answer

Several factors can affect benchmark results: outdated graphics drivers, background applications consuming GPU resources, thermal throttling from high temperatures, power-saving mode enabled, browser settings limiting WebGL performance, or multiple browser tabs open. Close other applications and ensure your GPU drivers are up to date.

Question 18

The benchmark won't start. What should I do?

Accepted Answer

First, ensure WebGL is enabled in your browser settings. Try refreshing the page or using a different browser. Clear your browser cache and disable any browser extensions that might block WebGL content. If issues persist, check that your graphics drivers are updated.

Question 19

My results are inconsistent between runs. Is this normal?

Accepted Answer

Some variation between runs is normal due to background system processes, thermal conditions, and browser state. For the most consistent results, close other applications, let your system reach a stable temperature, and run the benchmark multiple times to average the results.

Question 20

Can antivirus software affect benchmark results?

Accepted Answer

Other software may affect results. Keep your usual security protections enabled, close unrelated applications and record the test environment.

Question 21

What technology does the benchmark use?

Accepted Answer

Volume Shader BM Test uses WebGL (Web Graphics Library), a JavaScript API for rendering interactive 2D and 3D graphics. It runs directly in your browser without plugins, utilizing your GPU through the browser's graphics pipeline, making it an accessible Volume Shader BM Tool.

Question 22

Does the benchmark stress my GPU?

Accepted Answer

Rendering can increase graphics load, temperature and fan activity. Stop the test if the device becomes uncomfortable to use. The site does not read temperatures or certify hardware stability.

Question 23

Is my benchmark data stored or shared?

Accepted Answer

Benchmark measurements stay in the browser and can be downloaded as CSV or JSON. There is no benchmark-upload or leaderboard service. Pages also load the third-party analytics script from wang.632932.xyz.

Question 24

Can I compare my results with others?

Accepted Answer

For comparisons, keep the shader, resolution, browser, refresh-rate limit, power settings and background load similar. Results from different environments are not interchangeable hardware scores. After measuring, use CSV or JSON to download a result snapshot, including browser, operating system, GPU information and metrics. The download is generated locally.
