Example B of not knowing what you're talking about.
"There isn't even anything like Rift Apart currently available on PC tech wise" has nothing to do with raw visuals and instead the data streaming tech on display that can literally change entire levels with the press of a button and no load screen at all. You know, what we're talking about here, data being uncompressed and streamed into the game.
If you really think that texture being compressed in the game files is going to make it look worse on your screen you are completely lost. The tech literally decompresses it before you see it. That is the point of it. Holy cow batman.
