Oh, they noticed. They complained. They said "we need to fix this".
The project manager said "Not high priority for launch", then closed the ticket.

The site none of us can read probably has more info about this being a RTX 4090 quirk. And it's not exactly surprising the dev team wasn't optimizing for RTX 4090, and the quirky reaction here would be justified if they were.
NVidia absolutely changes the assembly language rather dramatically between iterations. That's why the code is in NVidia PTX (or HLSL / Microsoft's DXIL, DirectX Intermediate Language), and then recompiled to actual GPU assembly each time you install a game or run the code on a different system.
Perhaps back in the very early accelerator days when everyone was making GPU-specific hacks of Quake 1 but even that was smoothed over by the transition to DirectX/OpenGL/GLiDE at the time
Two years later: "WE NEED TO RELEASE THIS TOMORROW. JUST MAKE IT BUILD AND SHIP IT!"
