WebGPU Benchmark: 15M Moving Nodes in Browser
- ajlaston 11mo agoI’ve been experimenting with WebGPU and built a benchmark that simulates and renders up to *15,000,000 moving nodes(rectangles)* in real time in the browser. Each node has its own position, velocity, size, and color. All simulation and rendering happens entirely on the GPU: • GPU compute shader updates positions • GPU performs visibility checks • GPU maintains a visibility counter via atomics • Indirect draw calls per chunk • CPU does minimal work (just submits commands) The demo starts at 50,000 nodes, but you can type any number up to ~15M and reset. Warning: This is a GPU stress test. Large node counts may cause slowdowns, thermal spikes, or browser crashes on some hardware. Demo: https://ajlaston.github.io/Nova-Web/ https://ajlaston.github.io/Nova-Web/ Code: https://github.com/ajlaston/Nova-Web https://github.com/ajlaston/Nova-Web I’d be interested in performance reports across different GPUs, browsers, and platforms. Feedback on the architecture is welcome.

- ajlaston 11mo agoGreat! I pushed it to 120 million and my PC froze. There is diffing and culling but in this benchmark all nodes are drawn since they exist within screen bounds.
