Unless you show me some receipts that said "preset" is something that actually heavily optimizes the code specifically for the Steam Deck APU, I'm gonna assume that it's nothing more than optimized menu settings for the best performance on a Steam Deck which is completely different.
The fact that the steam deck is running the same x86 code handheld as any current gen console or 4090 powered desktop seems to be completely lost in this conversation.
The entirety of the game code needed to be refactored to run on switch2, and then many months were spent to optimize the experience further.
I don't think anyone in their right mind is denying that the footage they're showing looks incredible.
*edit*
Thinking about it some more as someone who is currently playing it with path tracing with either m+k or with dualsense -
Switch2 will probably be the best way to play it - with motion controls.
Graphically it's very capable and to be able to play it at a mostly locked 30 swigning my arms around for the sword and gyro aiming with the second controller...
it's going to add a whole level of immersion that path tracing doesn't.
Holy shit... driving in the game is mostly crappy with either controller and even worse with the keyboard.... are we going to be able to mario kart motion control the driving???
Yeahhh. these QOL improvements might make this the best version.
and the fact that the whole game runs on a small chip
it's so meta, that does make it seem like the most cyberpunk way to play the game.'
edit2
oh my god, are we going to be able to motion control drive with one hand and use the other to aim and shoot during the vehicle shootouts????
