twitch 8000 bitrate

I will not stop. I will not support advising others to have a crappy stream just so some low end bobs can watch it. That is harmfull for the complete platform because than you simply ignore everyone under 100 viewers because you know the quality is so shit it is not worth to even click on the stream even though it sounds interesting.

Low bitrate does not mean crap quality. It means leaving off the luxuries (like 60fps), and working within a tight bitrate budget to make yourself as accessible as possible, to give yourself the best chance to succeed.

Again. Please stop giving shitty advice to people who don't know enough to realize how harmful it is. You've been doing it for a while.

resolution will kill the quality, fps don't have that big of a impact on the quality.

And again, no. There are no studies that researched that field, so you could be right or talk complete bullshit, there is no data to back this up and no, studies about the network speed at the end of the world on a mobile device don't target this usecase, you would need data from twitch for this to see the min speed values viewers reach and they don't publish that as far as i know.

Doubling the FPS literally near-doubles the bitrate needed to maintain a set image quality level at the higher framerate.
You are entirely talking out your ass.

Livestreaming is literally my full-time job. I make my living doing it.
Please. PLEASE. Stop giving newbies bad advice.

And that shows why just because you are doing something makes you no expert in it. You don't seem to understand how a encoder works.

This would only happen if you stream uncompressed bitmaps, but that is not the case.
See for example the results from xaymar

There is no correlation between you streaming full time and having any knowledge on that topic.
If you would work as system architect for a streaming plattform yes, but as a simple user no, you are no better than any other random dude on the internet giving recommendations. Maybe actually worse because your expierence is years old, asking a magic 8 ball could get me better results on what is the right bitrate currently.
So if you find research to it from twitch or a other gaming oriented website, point me to it and will create my conclusion if I should stop recommending the best quality that is possible but until that i will ignore you.

Speaking of magic 8 balls, I stream pool matches. The majority of the time 50-75% of the screen is static. Because of this I get decent (not broadcast) quality at 3072 Kbps using the rig in my sig (I've since switched to VBR 3072-5120 and works great on FB, Twitch and YT). I tried streaming a few times at 59.94 FPS at CBR 3072 and the quality instantly turned to garbage.

quicksync is no effective encoder (amf is even worse) in the first place, trying that with nvenc or x264 at medium should give you better results at maintaining the quality while increasing the fps. If your compression ratio is low at the start it makes sence that doubling the FPS will result in a much bigger quality loss against encoder settings that are very effective.
 
There is no higher bitrate limit for Partners. I am one.

8000kbps is simply a word-of-mouth, entirely unofficial "known good" value that mostly works.
There is no technologically-enforced upper limit to how much bitrate you can use. (Staff MAY come in and ask you to turn it down.)
I have successfully tested with up to 12mbps, but as you go higher, more people will receive Network Errors and player blackscreens.
Your stream may stop being replicated if the ingest server is unable to process your incoming bitrate. A partial will end up with the Source option being removed, as the ingest/replication/transfer stack failed, but the ingest was able to feed into the transcode stack to the point THAT feed can still be replicated and transferred to the local video delivery CDN servers. It isn't Twitch 'turning off Source'.
Audio bitrate IS factored in.
The difference between 320kbps MP3 and 128kbps MP3 is significant. 320 and 128 AAC (which OBS uses) is mostly un-noticeable unless you're listening side-by-side. I've run down to 96kbps and no one noticed. 160 is as high as I'd bother going on audio.

The drawbacks to high bitrate:
Your viewers WILL receive more player Network Errors and have to reload the stream.
Unless you are a Partner with guaranteed transcodes (quality options), running at a high bitrate will reduce the accessibility of your stream. The higher bitrate you stream at, the fewer people will be able to watch smoothly. Running at a high bitrate without guaranteed transcodes is MASSIVELY shooting yourself in the foot; to grow, you need to make sure that ANYONE coming in will be able to watch your stream, before worrying about wanking over 1080p or 60fps video.

Number-wanking is hands-down the BIGGEST newbie-trap. I fell into it myself at the beginning. A 720p30 stream at 2000kbps with good mic audio and game/mic balance will gain and retain FAR more viewers than cranking the dials to 8000+kbps to satisfy the number wanking "must have 1080p60!!!11!!" that many new streamers do.
For me I cant start with more then 8500 like TRYhd says. Are you partner?
