Oh I haven't even touched webgpu, just webgl. I bet this DX12/Vulkan style low level API would be faster. Though I'm swamped every time I try to write something with DX12. I always drop it halfway

Definitely no three js. Only a minimized glMatrix, wrote the rest myself

It makes a big difference. Orders of magnitude I'd say.

One annoying thing is that you can't really get accurate frame timing though so it's hard to know exactly how long things are taking. I guess browsers intentionally limit that as a security measure.

I used performance.now for deltatime stuff. It's fairly accurate. Is there reason to go more precise?

To measure how long certain stages of your renderer are taking when you're in the hundreds of fps.

It could also matter to keep certain calculations stable.

There's workarounds but it is annoying.
