Hardware Encoding?
Not sure if the streaming supports using the GPU to encode video.

From what I can tell, there's a spike in CPU usage when actively streaming. This has caused some hickups while playing and streaming.

Nvidia's GeForce Experience supports gpu encoding and streaming to twitch. This would cut CPU usage, and improve the experience for both sides of the stream.

Did I miss an option or is this a planned feature?

EDIT DEC. 07 2014: Please look at this post http://steamcommunity.com/groups/steambroadcasting/discussions/0/624076751520173836/?tscn=1418014412#c624076851231796066

EDIT FEB. 10 2015: A Valve developer has clairfied that settings in the In-Home streaming settings page DO NOT affect that of Steam Broadcasting. You can read more here: http://steamcommunity.com/groups/steambroadcasting/discussions/0/611696927918145855/#c611696927919546172

NoNo, you just need to ENABLE hardware acceleration in the in house settings (host settings).
Can't reproduce on my system, In-Home streaming works great with HW enc., broadcasting performance is unaffected either way.
i7 2600k Win8.1 (quicksync and shadowplay available and enabled)

It could be confused as to which one to use, try disabling shadowplay and see what happens.

wow, this is interesting. For those of use who livestream. I can't wait for this feature to reach Linux. I'm better Valve hasn't pushed it to Linux yet because hardware encoding is still very very new to linux because Nvidia.....DAMNIT Nvidia we want nice things as well. :) Nvidia just released nvenc support about a month ago and it's not really implemented in any software except a ffmpeg fork which I am testing as we speak. OBS won't rouch is, Simplescreenrecorder won't touch....both projects feel that x264 CPU encoding can't be beat quality wise BUT i don't think they fully appreciate the capability of the nvenc chip. It can do (4) 1080p@60 (i think, i'd have to review to docs again) streams at the same time. THAT'S ♥♥♥♥♥♥♥ scalability right there so it may not make sense for average consumer use cases.

I tried the HW Acceleration under In Home, but still getting single digit drops on some of the games.

System:
i7 5960x
2x Geforce 980s
32 GB RAM
100 Mbit/sec Internet connection

I've dropped the ingame resolution to 720p, and lowered the bandwidth. It seriously should not be this bad (as the games I were playing weren't exactly system stressers).

Remember that the product isn't going to be optimized as of yet. It's close, but not quite where it should be.

On a side note, single digit drops on some games (I presume 0-9) isn't that bad.

Your CPU is really really powerful, you don't need hardware acceleration.

I only use hardware acceleration because i have a low powered mobile cpu, if i had the option, i woudn't use it.

Thing is though if it was encoded to H.264 then it would help a lot. Compared to whatever it uses now.

My mistake. I meant the game is running in single digit fps. Currently playing Legend of Heroes, and it's really difficult to play if anyone watches. (And this game doesn't exactly chew up much of the CPU/GPU to begin with).

Do you have hardware acceleration on (in house streaming settings)? I know that hardware acceleration has problems with some computers.

so i wonder, did Valve make it so that the steam client utilizes hardware decoding? cause amd, nvidia, and intel all have hardware decoding of h264 streams which i am assuming is what valve is using for this steam streaming

I think we both know that the client already has hardware decoding implemented for In-Home streaming. As for decoding broadcasts, no idea.

ok awesome, i didn't know since i haven't used in home streaming yet. now i wonder if i could get steam on a banana pi. ;)

I don't know about the banana pi but there is a nvidia gamestream client for raspberry pi: http://limelight-stream.com/ - https://github.com/irtimmer/limelight-embedded

Since Steam broadcasting is out of beta, anyone knows if it has improved performance? if they offload the encoding to gpu?

I'm still at uni so I'ma report back later
