Most gamers don't even have 4K yet, but we know how the industry works - give them one set of technology, while pushing another, but work on an even better technology behind closed doors.
Well, 8K is beginning to show up, with a new Crysis 3 hack that allows the first-person shooter to be run at 8000x3333 pixels, or 8K. The screenshots don't really do it justice, while they do look pretty, I think the effect of 8K would be better seen in person, on the display itself. Even if you ran 8K, you would need some serious, serious GPU horsepower to get there. You can see more of the screenshots of Crysis 3 running at 8K right here.
But, 8K? Is that all you've got? Keep an eye here at TweakTown for even higher resolutions in the coming months.
