Who's problem is this?

Nvidia probably doesnt officially say anything about this and 99.9% of people do not rename process name

It's definitely Nvidia's problem if this breaks something. Nothing in the D3D/OpenGL specs says that you can (not) use certain executable names.

Phrasing, I wasn't blaming anyone, just curious about the technicalities.

of course they do.

nvidia even has an official api for a game to identify itself so they dont need to look at executable name
