I tend to play stuff at 40fps because my experience of it is that I feel like I’m getting 90% of the way to 60 (playing a lot of 30 until mid-20s will do that to you!), and then shift up to 60 if I have headroom or the game in particular feels rough at 40. My main machine has a 120Hz monitor and it’s lovely for some games, but it’s something I ‘feel’ on the mouse more than I ‘see’. I just can’t imagine using it on my deck for the vanishingly few games that can hit 90 on the Deck and then caring.
But, I’ve seen claims like ‘setting it to 40Hz will make it run 40 in an 80Hz container’ (some Nerd Nest video or the guy on it who does a lot of battery testing), or the PCGamer review which states the OLED can take “a game locked at 30 fps and triple each frame so it runs like butter at 90Hz”.
Is this just referring to, say, response time / latency?
I cant remember which youruber was reviewing the oled SD that said it felt better on the menus even.
He went on to say how human mind takes all these little inprovements and translates it to a smoother feeling performance even if the framerate hasn’t changed.
