Woah you're not going to see pop-in and clipping disappear from videogames within this decade(possibly even the next) that's very obvious really.Can you give an (in-depth) explanation / link why this isn't going to happen any time soon?
That's how a streaming tech works, hence it's called STREAMING. You see the data around you on screen and as you move the data required is streamed in, that's the very essence of it. The other option is to load the entire level in the memory at once... we don't have that much memory and won't probably never "enough" memory to have everything at once since data increases exponentially while memory doesn't.
