The only reason to run a game in 4K resolution now is if you want to play a PC game on a very large display without degradation in pixel density/image clarity compared to a smaller screen.

The jerky movements you encounter are probably a dip in FPS because of the extra horsepower needed to render in 4K.

HAHA. Nope, PS5/XBOne2? Will be the 2K gen as the standard and 4K as the exception like 720p and 1080p last gen

Next Gen or perhaps Next Next Gen then i come back...

Nice question to ask in a mainly console-gaming forum. We won't see 4k gaming this gen...

THIS, close topic.

I dont see any reason the Xbox One can not play say a 16 bit game at 4K. I know MS said the One supports 4K. Any similar statements frrom Sony?

Of course Sony said the same before PS4 launch. And of course they said it in a way like MS but to everyone it was clear that they only meant Movies and not games, unless they make Pong in 4k.

I have never seen a 4K screen yet, but frankly, I would much rather take 120fps refresh over 4k, I like the extra details as much as the next guy, but I want more realistic movement... and I have not looked at the thread, but many people will probably post that silly graphic that tells you a 720p screen is more than the eye can see!

Well, MS made a statement about the console outputting at 4K, Sony did as well, but they won't let games output at this resolution yet.

However in the PS4's case, we have some developer commenting on that the performance was like for Trine 2 game on the devkit:

"It runs at native 1080p at 60 frames per second - but that's just the beginning of the story. Frozenbyte's impressive Trine 2 has migrated to PlayStation 4 in fine form - not only does it combine the optimal mix of resolution and frame-rate, but it's the only game to support stereoscopic 3D, running internally at an effective 1080p120 in the process. Indeed, according to the developer, Trine 2 could even hit 4K at 30fps should Sony ever unlock the output of the PS4 to support ultra-HD resolution."

This is not a very demanding game, but it tells us that in some cases people may decide they want this options (I prefer 1080p60fps... smooth is better and so far most games cannot hold their 60fps, many don't even hold their 30)

well, I have no screen at home on which these videos would make any sene to watch, not to forget the huge compression of youtube which would let it look much worse as "real" 4k stuff but at least the football demo in the store close to me on that huge 4k tv looks pretty great when you sit only 2 meters away of it so that it would be probably also fun to sit so close to a tv with games running in 4k.

but if it would mean that the rest of the graphics would have to be reduced i would rather go with a lower resolution to have better lighting and so on...
