Question / Help Minimize Network Impact option?

[Laope]

Im changing from classic OBS to OBS studio, i love it but there is an option i cant find anywhere: Minimize Network Impact.

without that option i cant play multiplayer games while streaming with OBS studio. so right now im forced to go back to classic OBS.
there is a hidden menu? or some ini file i have to modify to use "Minimize Network Impact"?

right know with OBS studio i have 500ms ping on online games, but with OBS classic with Minimize Network Impact activated my ping is 80ms.

OBS MP is still in an early stage, so there's a lot of things from the old OBS that it doesn't have yet.

Can someone with more technical knowledge of old OBS tell us what that setting did anyway? Maybe there's a way to re-create it with some encoder parameters.

Think of it this way:

Normal stream sends packets to twitch, each packet is 2 long(Just and example)
--

With minimize network impact, these packets are increased to 4 long, meaning your router has to send less packets, effectively.

I'm gonna bump this and ask is there any expectation for this option ? For people with ~4/5mbits upload if you stream at 2-2.5k bitrate game is lagging in terms of ping, usually FPS games but also including mobas. With minimize network impact you limit your bandwidth and you have clear limit for game.

No! It is exactly the opposite way!!

Lets say without MNI (Minimize Network Impact) it sends (just example numbers) 10 * 50kB packets every second. With network upload speed of 1000kB per second, your stream would eat 50% of bandwidth, sending every 100 milliseconds for 50 milliseconds. That means your game will always have to wait for the packets to send, game will wait up to 50 ms.

normally:
--------stream--------//----free for game---//--------stream--------//----free for game---//--------stream--------//----free for game---// etc

with MNI:
-stream-//----free---//-stream-//----free---//-stream-//----free---//-stream-//----free---//-stream-//----free---//-stream-//----free---// etc

If you stream smaller packets but more often, your game will thus have lower ping.
Is there a downside? Yes.
Every packet consists of so called control information (version, length, protocol, source IP, destination IP, ...) and actual user data. If you send more smaller packets, you will spend more network bandwidth on control information.
