15 years ago, I worked on a game that ran at 60Hz on a 333Mhz cpu on the PSP. It animated skinned transforms for a dozen rigs, transformed maybe 20k triangles and rasterized them, decoded and mixed music, and a dozen other things, all in 16ms. I think about that a lot when things are slow on my 100x faster computer.
@marshian I have similar thoughts when I wonder how my smart watch lags.
