According to a few more open indie developers, there is a laborious verification process at Valve. I distinctly remember the developers of Selaco detailing their frustrations that they made a native SteamOS version of their game and because that one was somehow stuck at Valve in verification, Steam Deck even defaulted to the worse Windows version on Proton.
I'm running an original steam deck, and I don't have frame rate issues. I had one cutscene lock up the system, but other than that one hiccup, it's been running fine on default low settings.
But lowering all settings to low and Dynamic Resolution to max 100 min 66 gets me back to 30fps everywhere
That's one of the criticism the author mentions early on. It's really easy for developers to build in a check if their game is running on Steam Deck and then select the performance preset. It's literally a task of only "if steamdeck=1 set performance profile to low" (so 1 line of code in most cases, a bit more work should they make a dedicated performance profile for Deck).
same. Ive played it for about ~10 hours on the steam deck so far, and i have my FPS counter turned on at all times; never seen it dip below 40, and i dont think ive touched any settings. On an original steam deck, not an OLED, though
