About slo-mo

[Sketcha]

I've played mario galaxy, and saw a lot of distant objects, which absolutely don't need to be seen for gamer.
Is it possible to add a feature, which will reduce distance of view???? Like in GTA, an option which controls field of view. It can boost up performance a lot.
Or maybe simplify distant objects ?

No. This is an emulator, not a game. Draw distances are handled by the game.
