How Particle Physics Tests WebGL & Compositor Throughput

Rendering thousands of physics-enabled particles in real time exercises several key graphics subsystems:

Vertex Transformation & Buffer Uploads: Updating particle coordinates and velocity vectors on each animation frame.
Rasterization & Alpha Blending: Calculating overlapping particle transparencies and radial glow gradients.
Compositor Thread Lock: Verifying that the browser's main UI thread does not stall during heavy GPU memory transfers.

Technical answers to common hardware, refresh rate, and browser diagnostic questions.

How does this in-browser GPU stress test compare to 3DMark or FurMark?

While native benchmarks stress 3D DirectX/Vulkan pipelines, our browser benchmark specifically evaluates HTML5 Canvas 2D and WebGL rendering throughput, browser compositor overhead, and hardware acceleration efficiency.

What is a good GPU Stress Score?

Scores above 8,000 points indicate high-end GPU acceleration capable of handling complex web graphics and 240Hz+ gaming displays. Scores below 3,000 indicate integrated graphics or disabled hardware acceleration.
