Reply to comment by TheLuminary in ELI5: how does rendering a video game resolution above your monitor resolution make the picture more crisp? by ItsSnowingOutside

This is called mip-mapping by the way, and in modern games this process happens all the time.

Mip-mapping is slightly different - it's automatically using smaller versions of textures for far away objects, which speeds up rendering and makes the distant textures look better as the GPU isn't good at scaling textures down more than 2x.

What OP is talking about is better described as antialiasing.
