It's a Ultra HD remake of Super Mario 64 (Super Mario 4K), My PC (Windows 7) going very slow, because it isn't so powerful that it works for me optimally.
Could you put a graphics quality selector for less powerful PC's?
Ah Ok, you can't for reasons of Copyright (DMCA), it will happen like the ones I found in 2016:
No Mario's Sky: https://asmb.itch.io/no-marios-sky
Other games: https://itch.io/takedowns/71240
But at least you could leave me a link from google drive or mega, that will not give you so sudden claim, well, it doesn't matter.
