After reading this Eurogamer.net article about PC gaming in 4K resolution, i decided to see for myself how big 4K resolution really is(or atleast 3072p), the nearest thing i could do was rendering a picture in 3072p, and rerender the same picture in both 720p and 1080p, then compare all.
the 3072p picture took quite a while to render, but the end was quite suprising for me looking at the comparison(also 48mb TGA file), if thats 3072 then 4K is definitely huge, but the question is: In what way is it useful? because 1080p is really high-definition enough to my eyes.
