4k In-Home Streaming

[Zenf]

Hi,

I wonder if it will be possible to stream a game with 4k resolution from my PC to a cheap steam machine?

Best regards.

I wouldn't count on it, going to 4K will increase the requirements in terms of encoding time, decoding time, and bandwidth, and that may just be slightly too onerous to produce a good experience.

4k (aka 2160p ) propebly it takes 4 times the bandwidth as 1080p, and most computers can't steam 1080p video without Lag or quality loss. I doubt it will be happening soon.

Not many PC can't even render a 4K image 60 times a second from a game. Plus Most games are currently built with 720p/1080p in mind.

I expected bandwith problems... Real 4k gaming on TV might be still a dream for several years (if you don't want to have a nuclear power plant / pc) in your living room. Unfortunately...

I think the bandwith of your local network would suffice, especially if you have ethernet between devices as opposed to even the most solid of wireless connections, but I wouldn't put money on it.

Expect 1080p, that's my bet. I mean, Netflix is starting to stream 4K content over the web to clients, but again, that's yet to be proven a success. But should it be a success, pushing that over a tightly woven local network isn't implausible.

Unlikely though? Yes.

There are hardware and software solutions of upscaling to 4K but they do not fulfill their claims going by reviews. one example http://gizmodo.com/upscale-to-4k-cheap-roku-and-cheaper-lightning-cables-1449114227

My issue isn't the streaming the Video, it's showing Video on another device within fractions of a second after it was made. Remember that a delay of half a second is game over for some games. For watching Live sport, such Football, It doesn't matter as much if the action is a few seconds behind what is happening on the field.

My other issue is that the host PC needs to be powerful to render the images in real time. I heard that the PS4 can output 4K content, however in the same comment it says it would be limited to Video and Pictures, games would be at 1080p.

True, but you can artificially delay a video signal to synchronize with input (which is actually likely what they're doing in small bits of this tech).

Plus, not a lot of folks (even PC-saavy gamers) have 4K tvs or 4K monitors at that. So I think pushing for a feature of that sort is not on Valve's to-do list.

Yes it's possible to stream but I doubt you have the hardware for it.

Linus pushes the limits of the in-home streaming tech. He even has 4k streaming working. however it isn't perfect.. It's a very interesting and informative video, I recommend checking it out:

I'm going to test this next week. I have a pair of overclocked GTX 780 Ti GPUs on the way and I got a pair of Seiki 4K displays last week.

I'm really worried about the encoding side. Software capture and h.264 encoding 4K even at 30 frames a second is a very big ask for even a top of the range CPU.

[Zhnu]

4k encoding will be a brutal task for any consumer grade cpu, but as you must noticed already steam in-home streaming does loose a lot of picture quality in order to be low latency and easier on cpu, you might get lucky but don't know if it's worth spending extra computing/bandwith just to achive 4k resolution I would mutch prefer a 1080p stream with a better encoding profile.

[cros13]

I'm going to try it out just 'cause I can. Day-to-day I'll be running 1080p streaming on some intel NUCs and using 4k upscaling.

I have 3 1440p monitors in portrait surround for a total of 4320x2560 and a seiki 50 inch I've attempted numerous times to get 4k streaming and I was semi-successful in two games. First game was Half-life 2 which was extremly jittery and jumpy (unplayable). The other game was Sleeping Dogs and that only worked in windowed mode (3820x2160) and was jumpy and jittery in the opening sequence but settled down to a fairly smooth game averaging around 20fps. My biggest hurdle was dealing with the different aspect ratio's.
