Question / Help Arch Linux - slow frames on stream [ENG/GER]

[cxrx]

hey there,

I have been using Arch since 2015 and struggling with obs-studio for 3 days.
After all, I got obs-studio, it started "lagging" due streaming. Let me explain this "issue".
Yesterday, it started buffering after a several seconds like every 3-6 seconds. Today, it seems like streaming continously but on a low stream speed 0.2-0.5. Optically, I would say the stream runs on slow motion.
But I don't have clue, why it occurs...

CPU: Intel i7 3770k
GPU: Nvidia 680 GTX
SSD: Samsung Evo

OBS Setting

Encoder: just listed one x264
Broadcast method: CBR
Bitrate: 1600
Buffer size: not custom
Keyframe: 2
CPU presets: superfast
Server: tried variety server spots e.g. frankfurt, france, sweden, ...
scale filter: bilinear
FPS: 30
NV12, 601, limited
stream delay of 20 seconds
reconnect: yes

Also have installed Windows 7 on hard disk and tried to stream - same issue ( operating system independent )

Can you post the results from this: http://www.teamliquid.net/forum/tech-support/478845-twitchtest-twitch-bandwidth-tester ?

I will give it a try. Going to log in to my windows first, before I can run the program. Thanks for you answer!
@Boildown Updated information.

So that's not it, that looks fine. I guess on OBS-Studio lagged frames are like duplicated frames in OBS Classic.

00:10:17.060: Output 'adv_stream': Number of lagged frames due to rendering lag/stalls: 791 (2,5%)

You probably want that number to be less than 1%. You need to decrease your encode settings to decrease that number, can you try downscaling to 720p?

 

[cxrx]

I have decreased it to 1280x720 from 1920x1080 in encoder settings.
I'm curious, what does in "Video" -> "Output (Scaled) Resolution" mean?
I have changed the settings in encoder settigs to an output of 1280x720, do I have to change it in "Video" also? I don't think so...

Anyway, here is the stream. I'm going to hit university class. Going to shut the twitch-stream down at 10-11 p.m.

Edit:// more information

What I have discovered: The ram usage is almost 15 GB of 16GB virtual memory.
When I close obs, its getting back to 1.2GB of 16GB ram usage.

Edit:// After I closed obs and restart it, it took around 2GB of 16GB ram usage... I don't get it.
When I streamed for like 5~15minutes, it took ~15GB ram usage..Now its just holding himself back with 2GB/16GB ram usage.
