In what sense? The render loop is modified from “the” default without user or program opt-in, and “hijacking” is what it would be called if anyone but Nvidia did it — so Nvidia is not exempt from that use. Though: Runtime patch, haxie, hijack, LD_PRELOAD, system extension; the noun changes every few years, so perhaps it’s time for a new one. Override?
But the comment I replied to wasn’t talking about runtime patching or any of the other settings you mentioned. It was talking about changing GPU settings for specific programs. Not changing anything about the program itself.
