Volume Shader Maximum GPU Stress Test

Welcome to Volume Shader test site, the definitive platform for testing your device's raw graphical performance. Whether you are running a high-end gaming PC or the latest flagship smartphone, our volume shader test pushes your hardware to its absolute mathematical limits.

Most benchmarks rely on textured polygons. We do something different. This tool renders a complex, organic structure using a technique called volumetric raymarching. Every single pixel on your screen is calculated individually, hundreds of times per second, to simulate light passing through dense matter. This makes it the ultimate volume shader gpu test for verifying ALU throughput and floating-point precision.

What is Volume Shader?

Volume shader is a specialized WebGL application designed to evaluate GPU efficiency. It works by "marching" rays through a mathematical distance field to render a 3D shape without using a single 3D mesh file.

Because it runs entirely in your browser, it is the perfect phone performance test solution. You can instantly compare the performance of an iPhone, Android device, or a desktop RTX 5090 without installing heavy applications.

Test Features

Real-time FPS Monitoring: Check your volume shader fps instantly as you rotate the model.
Multiple Complexity Tiers: From "Simple" for older phones to "Extreme" for a max volume shader test.
Cross-Platform: Works on iOS, Android, macOS, Windows, and Linux.

How to Run

1. Tap "Start Benchmark".

2. Select a preset (Default: Simple).

3. Observe the FPS counter in the top left.

4. Drag to rotate the volume and stress different GPU cores.

// Goal: Maintain 60 FPS

Test Controls

Action	Function
Left Click / One Finger	Rotate the volumetric model (XYZ axis)
Right Click / Two Fingers	Pan the camera view
Scroll Wheel / Pinch	Zoom in/out (Adjusts `len` uniform)

Frequently Asked Questions

Why is my FPS so low on mobile?

The volume shader bm test phone workload is incredibly heavy. Mobile GPUs often throttle to prevent overheating. Try switching to the "Simple" tier, which reduces the raymarching steps from 1002 to 250.

What is a good score for RTX 5090?

For a volume shader rtx 5090 test, you should expect to easily hit 60+ FPS on "Extreme" settings. If you are getting lower, check if your browser has hardware acceleration enabled.

Can I run this test on iPhone?

Yes. This test is fully compatible with iOS WebGL. Newer devices like the iPhone 15 Pro perform exceptionally well due to their advanced GPU architecture.

Final Verdict

This tool remains the standard for web-based graphical stress testing. Keep your drivers updated, close background tabs, and aim for that perfect 60 FPS.
