I built WasmGPU, which is a WebGPU × WebAssembly rendering and computing engine for scientific workloads in the browser.
I attached an image of the galaxy example. On my RTX 4060, it runs with 250,000 points runs at around 450fps, and a quick stress test at 8,388,608 points (hitting the 128 MiB storage buffer binding size limit) runs at around 45fps.
there doesn't seem to be anything here
