> And the fourth is generating all the data. You need absurdly high definition textures, which requires lots of VRAM, lots of regular RAM, lots of disk I/O, lots of disk storage (your average AAA game is well beyond 100GB of data at-rest for a reason!), and then render power to actually render the scene. 8K has 16x (!) the pixels of regular FullHD (1080p).

You don’t need to scale everything up to match the monitor. There are already benefits to higher resolution with the same textures for any object that isn’t directly next to the player.

This isn’t a problem at all. We wouldn’t have to run games at 4K.
