Question / Help Best setting for i7-5820K on Twitch?

[Rumlik]

Hi All,

Already nearly a year I streaming (World of Tanks) on Twitch(non partner on Twitch), on this configuration:

CPU: Intel Core 2 Quad Q9650(4x3.00GHz)
RAM: Corsair Dominator pc8500 1066MHz DDR2 dual kit 4GB (2x2GB)
MB: ASUS P5Q-E

1080p/24FPS/2500 bitrate/x264/CBR/Superfast.

The image was not ideal, because the old-fashioned processor, but it was decent.(I have no problem with upload speed 50+Mbps). Bitrate I reduced as much as possible with regard to viewers and with regard on old CPU.

Now I bought a new configuration:

CPU: Intel Core i7-5820K
GPU: MSI R9 280 GAMING 3G
RAM: CRUCIAL Ballistix Sport 16GB (2x8GB) DDR4 2400
MB: ASRock X99 Extreme6

I've been waiting a major improvement. I tested different settings:
1080p/60FPS/3200 bitrate/x264/CBR/fast - medium- slow
720p/60-30FPS/3200 bitrate/x264/CBR/fast - medium- slow
but the image quality is basically at the same level as the old PC configuration. If I set the bitrate to 4000+ quality is significantly improved. Can I do something better, in compliance with Twitch restrictions / recommendations 3300 bitrate, for non partners?

I have the i7 5820k too , clocked at 4.6 Ghz. I myself run 720p @ 60 FPS, 2500 bitrate/buffer with a medium preset. Looks decent, depending on the game you play. It looks very good in counter strike, league of legends or any other slow paced game (I know counter strike isn't slow paced, but it still looks good, because of the contrast I suppose). But those settings will become pixelated in games like battlefield, which are more difficult to render for the x264 codec. For those games, I run 720p@45 FPS 2500 bitrate with a medium preset.

I myself also noticed that the Filter can have a big effect on quality. Lanczos looks very sharp, but will only look good if you have enough bitrate for your resolution/fps. 720p @ 60 fps at 2500 bitrate is a bit too low of a bitrate and can cause pixelated images when using the lanczos filter, but it looks fine with the bilineair filter, although a little bit blurrier.

So play with the settings a bit more. Out of experience, I can say that that processor can take A LOT. so play around with presets and filter a bit, until you find a spot you like.

BTW: Don't exceed 2500 bitrate as a non partner, twitch servers are crap, and will cause lag for viewers, even if they have a connection of something like 150/150. Many people say 2000 bitrate is the golden point for non partners, but 2500 bitrate is also watchable without buffering, and gives you the ability to add some framerate, for a more smooth image.

CritVV - thank you for your reaction. World of Tanks is in this very specific. Quick motion scenes in fast sequence changing with slow motion scenes and in the game is a lot of small things for rendering. So 720p/60fps/2500 bitrate video is very blurry and pixelating a lot in motion. On a bigger monitor, it is then too bad (I myself have 30 "/ 22" and 19 ") and only on the 19" it can be overlooked.

I asked my viewers/fans what quality is the most pleasant for them and I did together with them various tests (it was quite fun).
This is the result:
Tonight final stream: http://www.twitch.tv/black_hole1/b/596459368 It is: 1080p/60FPS/3200 bitrate/x264/CBR/fast. This time, I omit the item Buffer size and left her empty. It is a little bit blurry in motion, but at a slow scenes, the image is almost crystal clear. None of viewers had trouble with lags, so I'm moderately happy. :-)
