alt Hacker NewsTying physics to framerate at all is a mistake. Like, should be filed as a bug mistake.
There's no scenario in which that's desirable.
And yet even Rockstar gets it wrong. (GTA V has several framerate dependent bugs)

I completely agree, but it's an easy mistake to make.

not framerate of rendering but physics running at (its own) fixed frame rate.

It's desirable for arcade games, which have fixed hardware including the display. There's no possibility of upgrading for better framerate, and the game can be designed so slowdown is rare or non-existent. Tying the physics to the framerate gives you very low and very consistent input latency with minimum developer effort.
