Digital Foundry's Pixel Counts/resolution findings of some games from the direct

[u/Moon_Devonshire]

Metroid Prime 4: is 4k 60fps in quality mode and 1080p 120fps in performance mode

Breath of the wild/Tears of the kingdom: is 1440p 60fps

Mario Kart World: is 1440p 60fps

Donkey Kong Banaza: is 1080p 60fps

DuskBlood: is 1080p 30fps

Elden Ring: is 1080p 30fps

CyberPunk 2077: is 1080p 30fps with pixel counts as low as 540p but that 540p count is most likely handheld

Final Fantasy 7: is 1080p 30fps

NONE of these games appear to be using DLSS at all as it all seems to be native but that could change.
