Nintendo's trailer is in 1080p and it looks either native to me (except low texture resolution) or at least some very good temporal AA, better than AMD FSR. It is hard to say bc artifacts could be yt compression. Frame rate seems to be locked at 30fps (trailer is 30 only). I can see advanced techniques like per object motion blur and adaptive dof. It this all runs at >720p 30fps (as the trailer implies) it will be a miracle game for the Switch.

More than 720p native, no jaggies to be seen
Selective motion blur (and a lot of yt compression)
