hello guys :)
i am playing around with my Settings for a couple of days or week right now.

first my pc speccs :
CPU Intel Core i7 6700K 4x 4.00GHz
RAM Corsair Vengeance LPX 16GB
GPU AMD Radeon RX 480
Motherboard Asus Z170 Pro Gaming
Internet : 50 mb download and 10mp upload

Streaming Games:
league of legends, fif17, f1 2017, pubg and csgo.
at the Moment more pubg and f1 2017.

i have the Feeling that my stream is looking really shitty like Pixels everywhere and yeah.
(https://www.twitch.tv/videos/169919450 f1 2017 "gameplay")
(https://www.twitch.tv/videos/169546506 pubg "gameplay")

my obs Settings :
Video:
Basic : 1920x1080p
downscale : 1280x720p
Lanczos and 60fps

Output: x264;CBR;bitrate 3500;fast/medium (cpu usage around 60-100%)
or
Output: H264/AVC Encoder; twitch; Quality; Bitrate 3500 (cpu usage around 30%)
(i am playing around with this 2 Options)

i normaly streamed with Bitrate 2500 but i saw that you can Change the Quality of someones stream, even small streamers so i decided to go for 3500 with no partnership with twitch.

so what is my Problem?
i think my stream Looks really shitty and i wanted to ask you guys if you can maybe help me to make it better or if you have some ideas what i should do.
i am really interessted in Streaming and playing around with obs or something else but i dont know what to do anymore :D

i would be really happy if you could help me :)

they recommend max 6000 kbit and at ~8700 kbit you get authorization failed and your viewers can't see it anymore. so currently 8500 kbit is the best setting if you have viewers with fast connection and you want to deliver the max quality

did you tried it and verified its usable?
if 8700 is a cap and cuts off data, 8500 wont work because cbr fluctuates a lot same below and above its set value

i did try it and if you go vbr you can go up like 50 mbit, they just look at the metadata what there is written, funny thing is you can go even higher cbr if you start the stream with 8500 and than increase the bitrate while streaming.
Anyway i would not recommend to abuse that to much, in the end amazon has to make money and bandwith cost them money. But with 15000 bitrate and some cpu horsepower you can get crystal clear 1080p60 out of twitch. That looks even better than youtube

Edit and no you won't see frameloss, they don't throttle at ingest, if you go to high you just get a black screen saying authorization failed as viewer, but i never saw that after the stream did start successfull. Currently it seems like if you got it started they don't kill it while you are live.

I think this new system they introduced at the beginning of this year of a hard cut better than the system they had in the past then it did lag for your viewers or you had frames dropped. It does work or it doesn't there is no crappy between anymore.
