This runs like magic on an iPhone, but for some reason Chrome, Safari and FF on desktop (mac, recent mbp) it's sluggish as hell. Burning through CPU, 15fps for the force-graph. I feel like something's wrong, but I don't even know where to start debugging this. Do I need to enable Chrome feature flags? Or do mbps just have less powerful gpus than iPhones?

Chrome and Firefox on Android, on my Pixel XL, don't rise above 32 FPS. Chrome is a bit more performant than FF but not by much. I think you're right in your assessment; the iPhone's GPU is much stronger than you might think.

On my desktop (Nvidia 750 Ti , Windows 10) I get 60fps with Chrome, Firefox, and Edge on everything I've tried of the examples.

  Gave that a shot on the (Intel Graphics) Macbook Pro and wow, didn't even manage 10fps. Safari was worst of the lot.

Most examples are 60 fps, but on the last one I get 60 fps in MS Edge, but only ~35 in Chrome. IE won't even load it for whatever reason. Quadro k620

I'm getting 0.5fps with Safari Technology Preview, and a smooth 60fps with the stock Safari. I'm wondering what's up with that? I've tried both with and without the relevant entries I could find in "Experimental features" (WebGL 2.0, WebGPU, and something I forgot)

Likely has to do with the increase in the number of pixels on your desktop display. Even worse if you're using a high resolution external display.

  Mobile phones actually have a surprisingly high pixel count compared to desktops. FHD displays are common, and QHD and even near 4K displays are pretty common.
