We don't know the screen size of the Switch 2 and I very doubt it was 1080p (even the SteamDeck ins't on 1080p) Maybe 900p at least.
1080p for performance and ultra performance was 540p and 360p. But for 900p screen size, the target resolution gonna be lower.
And people thinking is DLSS 3.5 (with FG) gonna be on the Switch are fool, this is only for RTX 4xxx card. Also, not all games on Switch 2 not gonna support the DLSS. (Japaneese dev with older engine).
DLSS needed more VRAM for reconstruction too and more bandwitch if you want upscaled to 4K (so people thinking Switch 2 gonne upscale DLSS to 540p or 720p to 2160p are completly dreamer, taht's gonna be 1440p max).
Gonna thinking the console only cost 400$? Gosh it's gonna be more, we talking Nintendo and especially Nvidia Tech. If the console really cost less than 400$ then prepared to be very disapointed in power design.
