There were clear differences, one had more aliasing and wasn't running at very high res, also the snow effects after landing that snowboard was way shittier looking on the supposed Switch version. Though I can't help but wonder how that game would play with motion controls cause I kinda wanna play that with the joycons.
BTW, the supposed Switch footage looks like it's pulled from another platform, anybody that agreed with my graphics comparison needs to get slapped. ^_-b
