3 fps?
I wonder what an iPhone would get, I'm led to believe their GPUs are pretty strong (to say the least).
EDIT - The above was in Chrome. In Firefox I actually get 23/24 fps at 4k (3.83M particles). At 1.8M in Firefox I get 48-50fps. Pretty good from Firefox.
Doesn't seem hardware limited, CPU and GPU utilisation doesn't go above 20% and I'm running other stuff like a decent sized VM and some other programmes.
I really don't know much about WASM. Would these numbers be deemed good? Is there more performance to squeezed out? I'm guessing there is as it's not fully utilising the hardware?
EDIT: Ah just noticed I'm only using 586k particles.
