I definitely wouldn’t have a mandate, but I think standardizing the “Performance” mode to mean 60fps is perfectly reasonable and should be the goal of a developer, tested and set to guarantee that level of performance.
Also, on PC I now do everything I can to get as high a frame rate as possible, especially in the likes of Call of Duty, because it IS an advantage. And in games like Cyberpunk, I’m trying to get as close to 100 on average as possible because that guarantees staying at or above 60.
