it is yet another click away
I assume because it is in Beta stage. My hope is, that there is a setting in Steam to enable or disable this graph directly on the game page (in web browser and in the client).
Personally, I feel like the solution is that the Steam Verified badge should mean something. Solid 30 FPS should be the golden standard.
It actually means something. When the Steam Deck launched, an employee explained it means something like "the game should run like it would if this was on similar hardware playing on Windows", from performance standpoint. And off course it should be an experience like a native console game with default settings working right away. Also the "playable" and "acceptable" tolerance is different for everyone.
And that's the key point, it should behave like on consoles. I mean games on console are basically verified for that system, right? I mean any game you can purchase on Playstation 4 is verified for that system. It does not make any guarantees about performance or quality. And this is how I view the verification too. There are extreme cases, but that's not what we talk about.
Some would argue, 40 FPS should be the golden standard on Deck in example, instead 30. There are games which have a hard time to stay at 30 FPS, like Baldur's Gate 3, but are played a lot of the system.
