I think this question also applies to PC. Why? Because we are limited too. I try to reach 120 fps and consider it performance mode when dialing back quality settings, and enabling upscaling to reach that. If not, 90 fps is also pretty good. For certain games, 60 fps feels like what you describe of 30, but that does not apply to all games. There are single player rpgs played with a gamepad, that I would even consider playing at 30 fps if there is no other option. The problem is, games are not designed to be played with that low fps, as the input latency increases.

I’ll compare this to the Switch, playing Zelda (emulated with Yuzu). Breath of the Wild on original Switch is designed to be played at 30 fps. Playing it on my PC like that felt like a slideshow, but one can get used to it. If I didn’t had the 60 fps patch, it would still be fine at 30. The next game in the series, Tiers of the Kingdom, was not stable at 60, so I was “forced” to play at 30. And after some time playing it felt pretty good and not upsetting like in the first few minutes.

What I mean by that is, performance mode if possible, I would sacrifice quality. But not too much, because at some point the image looks really bad.
