GRID Legends on Switch 2 seems a very competent port; in graphics mode it outperforms the PS4 version with a dynamic 1440p resolution when docked, (PS4 is 1080p) and reflections that update at full rate. (They update at 15fps on PS4)
It also offers a performance mode that manages a mostly stable 60fps, where PS4 was stuck at 30fps, though this mode does cut back things like reflections and volumetric lighting to get there.
Curiously, the game does not seem to use DLSS on Switch 2 at all, instead relying on native res rendering.
