According to Torvenius,
Indiana Jones and the Great Circle will have 1080p resolution
in TV mode and 720p in portable mode . The version uses dynamic native resolution, maintaining full resolution for most of the experience, but resorting to DLSS when there are drops to preserve the frame rate and ensure stability in 1080p or 720p.
Regarding performance, the game will run at 30 frames per second on the Nintendo Switch 2. According to MachineGames, the decision to lock the frame rate at 30 FPS was made
"to ensure that the player has a solid, high-quality experience on the Switch 2 version, equivalent to that of other consoles."
