Steam adds Intel QuickSync to in-home streaming

[Ashley]

Along with some other tweaks and bug fixes Steam has added Intel QuickSync to in-home streaming!

 

This will lower latency, and could open the door to an Nvidia streaming update to Steam in-home streaming as well. I'm very excited to see hardware accelerated implementations being used by Valve.

I honestly thought they might just go for straight up software encoding/decoding but as of late they've been improving both in their streaming platform.

I cant wait for this to get to a point where i can stream games from my gaming PC at home to my crappy laptop while I'm at a friends

Meh.

 

Its pretty awful quality in reality. Its about the same as "superfast" on x264 (one of the worst presets x264 has in terms of video compression and image quality). You would be much better off using x264. You would be able to get higher quality video at the same bitrate as you could on Intel Quicksync.

In home streaming with a VPN can already do this.

True but I would like to see it implemented without having to use a VPN

And without as much latency. Just pinging home from the coffee shop could take ~50ms.

Two drivers ago nvodia release a api for their onboard hardware encoder and decoder so we should be seeing sfuff soon.

They increased the max nitrate Linus should test 4k no to see if he can get a higher frame rate now

I feel gaming will be optimized so much that low tier hardware will be able to run games on excellent settings

From what I've seen, QuickSync is pretty damn good in terms of image quality. Sure you can get better quality with CPU encoding but that requires far more resources.

Correct me if I am wrong, but isn't the SuperFast preset in x264 just for the encoding time and file size, not quality? So the quality will be the same when you use Ultra Fast or Placebo, but the file size will be different (placebo being the smallest)?

 

Anyway I think this is great news.

That or because the rate at which hardware is improving is slowing down. How do we improve performance?

Well maybe we could touch up that inefficient code in our engine/driver/software. For certain applications use dedicated hardware (like x264 encoding).

[Sigmatech]

The rule of Thumb essentially is.

NVENC (HQ)> NVENC (HP)>.264>Quicksync.

In terms of value to perf. (Opinion)

Moving edges are improved quite a bit when you compare the fast and the slower presets. There are comparisons on doom9 since im probably not allowed to post video here.

The next update better for family sharing... It sucks that you can't play a game from a friend unless he his not playing anything at all.

so If i am streaming from a pc with a Intel cpu to laptop with an AMD apu will I see an improvement?

no mobile site its better that tapatalk for WP

Yes. They sped up AMD decoding recently as well I think.

I'm pretty sure you can both game at the same time. Just not the same game, at the same time.

those presets dictate setting which basically dtermine how much time is spent compressing, not how much compression is done thats the bit rate or crf depending which you set.

thats my understanding as well

Not with the Family Library Sharing

 

Can two users share a library and both play at the same time?

No, a shared library may only be accessed by one user at a time.

You can't control whats in the shared library right now, so you cannot play any games if he is playing one of the other's games. If the other person starts playing then you have 5 minutes to get out of his game.

Can't wait for the better Nvidia support and the fact that lower end cpu's can decode it better now is very nice.

[totjup5]

Cool, but I won't care until I have a gigabit connection.

Wait Quick sync is only newer CPUs, right? So my older C2D will still suck at encoding?

Yes, anything older than Sandy Bridge won't support QuickSync (and you might not have support for QuickSync even if you got something from Sandy Bridge or newer).
