Прошу прощения за пост на русском, но гугл не помогает, а где ещё спросить я не знаю.Собственно суть проблемы: При стриме через два ПК (на первом игра, на втором трансляция) OBS загружает интернет на 100% (на первом ПК отдача становится ~99мб/с, на втором соответственно прием), интернет 100мб/с.При трансляции с одного ПК подобных проблем нет, отдача в пределах 6мб/с, прием и того меньше.

Это вообще нормально? Можно это как-то исправить?

Next time, go to Google and type in "russian to english".

"I apologize for the post in Russian, but Google doesn’t help, but I don’t know where else to ask. The essence of the problem: When streaming through two PCs (on the first game, on the second broadcast), OBS downloads the Internet 100% (on the first PC, the return becomes ~ 99mb / s, reception on the second, respectively), Internet 100mb / s. When broadcasting from one PC, there are no such problems, the return is within 6mb / s, reception is even less.

Is this generally normal? Can I fix this somehow?"

This is because you have a network infrastructure running at 100Mbps. I would recommend changing that to operate at gigabit.
The entire network must be replaced. Do this:
- Get cable modem, routers, switches, and hubs that operate at 1000Mbps (Gigabit)
- Replace all Ethernet cables, including patch cables, to Cat 6
- All network interface adapters must be operating at 1000mbps RJ-45 ports. If your motherboard doesn't support 1000Mbps, you can get a network adapter to put in a slot.

And the fact that OBS itself uses 100mb / s normally?

Why are you worried about 100mbps? Are you interpreting it incorrectly thinking it is in bytes? Its megabits, not megabytes.

The network column in Task Manager represents the amount of data transfer in real time being sent from a process over the network adapter. It is measured in megabits (not mega bytes) per second. In your screen, for OBS, it is telling you that it is transferring 95.3 megabits of bandwidth.

I brought up the 100 vs 1000 in case you were experiencing technical problems in streaming. If you are being limited at 100Mbps, you need to change your network infrastructure to 1000 Megabits (1 gigabit) if you are having problems. Increase bandwidth by switching out all networking hardware with faster equipment.

Here's a snapshot of my dual PC streaming setup to show you that what you are seeing is normal. The image below is of my NDI client (gaming machine). Here we see it is sending out 442.9 Mbps (megabits) over the network to my NDI server. Obviously, it would be not smart for me to use a 100Mbps networking infrastructure as it would slow its potential.

  • 1Mbps (lower case b) means bits
  • 1MBps (upper case B) means bytes

Clearly, it all comes down to upgrading the local network to gigabit.
However, if it’s not difficult, can you explain why when transmitting something like the same amount of information directly, without an intermediary in the form of a second PC, the Internet is loaded at ~ 4-8%, and through LAN at 100%?

Once the video data is encoded, it is very small, only a few megabits. But in raw format (before encoding) it is very large. With a single PC, video data is encoded on the PC and then sent out to the internet. With a two PC setup, the raw video data is sent over the network to the second PC to be encoded, which then encodes it and sends it out to the internet.

Now everything is clear. Thank you for help.
Sukiyucky, thank you very much.
