Hi guys, I have been getting kb/s drops while streaming, I never had this proble, I stream at 6000 bitrate 60fps and never had problems.

Now I drop to 3000-4000

I'm using Spain servers, because as you see I have a really stable connection. I think OBS use 64k TCP Window Size right? So it can't be the problem

I'll post OBS Log for you guys from a quick test streaming I did before, would be great if you can help me, tried everything :C

Killer E2200 Gigabit Ethernet Controller
if you use their software and not the intel driver that is your problem.

How can I solve this? Tried installing Intel Network Driver, but told me that I can't because I don't have an Intel Adapter

ah sorry that is a atheros not intel chip, so remove everything from killer that is on your system and install the atheros driver for your NIC.

What about CPU/GPU % usage during streaming ?
Have you enabled statistics panel on OBS and checked where is the drop issue ?
Encoding side or streaming side ?

Sorry, it's in spanish, I screenshoted the moment I got the bitrate drop. The problem is on connection, right? But as you see above, TwitchTest says I have good quality and good bitrate on the servers. And my upload speed is correct. Tested it uploading a 25MB size file

I am literally out of ideas, I am using atheros driver right now, as the user above told me. Same problems.

Thanks for your help guys

Maybe the issue is CPU related. In fact, I noticed that you have over 60% usage by OBS.
Check , with Windows Task Manager, the total system cpu usage.
Have you tried to reduce FPS, for example and check if issues still occur ?

More....
have a good speed is not a guarantee of good connection.
Have you tested your latency (ping) ?

Guys, have tried to stream on Mixer instead of Twitch and went perfect, 6000 perfect bitrate, sometimes dropping to 5700 but stuck in 6000 bitrate in general, 1% fps drop. What can be doing this, ONLY on Twitch? Can't understand

I suggest you do a stream test to other services instead of the one giving issues at 20mbps. FYI 20mbps is a lot! also the tool you are using to determine bets twitch server is a poor quality app. visit https://stream.twitch.tv/ingests/ and use the first server recommended to you, that is the better way to tell what to use,

My experience has been on twitch that as I encode and send out 6000kbps... not every moment of my video requires the full 6000kbps. therefore on mostly solid screens like black screens with text my bit rate drops out to twitch to tan adequate rate not the rate I set.

If you have "enforce streaming service encoder limits" check in the stream portion of OBS this could be happening due to that. also make certain to choose CBR constant bitrate not variable.

hope this helps

I am having the same issues here in America - Florida. Youtube and Facebook streaming work fine, I have 25mb/s upload speed and on the two closest servers (ATL and Miami), they both are around 4 kbps. Ive had my ISP come out and there is nothing wrong with my line - they even ran a new line and replaced the modem - same issue. Twitch wont give answers. Maybe ONE day out of the week can I stream on Twitch when the server says im getting 10k+ kbps and even then it still drops frames. Im using a 3700x streaming at 1600x900 60fps with 7k bitrate and even lowered that to 5k and it still messes up. My CPU usage is 30% so its not the CPU usage. Hell, Ive streamed on weaker chips using 70% of the CPU and it never impacted bitrate - the machine is literally only using OBS. At this point, I just think that twitch doesnt give a damn about you unless you are a big time streamer. I have friends in Pittsburgh with this same issue.

Than it could be a backbone issue.

Ill send an OBS log the next time I run it - I never run it if I see that the speed is under 10,000kbps on the twitch server test so I dont have a log from within the last 2 or 3 weeks that would show anything. Speeds seem to be higher today (my ISP speeds are exactly the same across 5 tests - 20 to 22 mbps upload) so Ill give it a try after work today

Also TryHD, I asked twitch support, who said they forwarded the issue to the "appropriate team"
