The video was just about SM64. I haven’t seen the video creator before so I’m not sure if he does other games.

Some of it was a bit over my head but I think he implemented a 3d driver (?) that came later in n64’s development which allowed for more polygons and stuff.

Either way, it was in no way an admonishment of the console! He’s a fan demonstrating what the console was capable of, not dunking on how SM64 could have been better
