Hello Guys,
im trying to stream Leauge of Legends with my Ryzen 2700x on twitch.
OBS Settings -> 720p60FPS (16 Bicubic) x264 medium

Always overloading Encoder, but OBS only uses 20% of my CPU ? Why isnt it possible to use 100% of my Ryzen ? With LoL i only have 30% usage ..
WIndows Game DVR and Bar are off, also im starting OBS 64-bit as admin ...

Can somebody help me ?

Shouldn't be struggling, I do 720p60 Slow on my 2700x while play way more intense games.

I've seen this exact issue before(not my system), opening LoL would force the CPU to only use 4 threads. I think it was Game Mode doing it? Yes, it's pretty much cancer.

Game Mode does stupid shit, especially with OBS. You don't have the toggle for it in your version of W10 but you can disable it in the registry

https://www.addictivetips.com/windows-tips/disable-game-mode-in-fall-creators-update-windows-10/

Check your CPU utilization graph when you have League open and OBS recording, check that you are getting CPU usage across all 16 threads

First 4 Cores working well but the other Cores .. Why they cant use the power ?

I also disabled Game Bar in the registry

Yup, it's the same issue. Not Game Bar though, Game Mode, same place though

HKEY_CURRENT_USER\Software\Microsoft\GameBar\

AllowAutoGameMode 0

If the key doesn't exist you have to create it. New>DWORD (32-bit)

Did you reboot?

As you have noticed it only occurs when you are in League, then stops when you are not in League or tabbed out

This LoL forum post goes over these steps and what occurs, Game Mode reduces your cores when League is open. (Not just League, World of Tanks as well)

https://boards.na.leagueoflegends.c...Rl-client-the-fix-weve-all-been-searching-for

So Option 3.

ENABLE Game Bar(for now), while in League of Legends hit Windows + G, click the gear icon on the right. Disable "Use Game Mode for this game".
Once done, you can disable Game Bar again


Option 4. Update to the newest version of Windows 10 so you get the toggle to completely shut it off for all games

ok looks good actually
720p60 @ slow worked fine for Leauge
What Games do u Stream with this settings ?

But anyway CPU usage @ 30% why can i not hit 70% for example ? When I try more than slow ->instant overload
Also a new problem my game is now locked to 60fps when OBS is open

How old is the update ?

I can do PUBG, Squad, Insurgency Sandstorm, etc.. I typically only do it for testing, I settled on 6000Kbps 720p60 Medium to give myself back some FPS. Yeah above Slow, no chance, that will cause your CPU to puke.

60 FPS lock. Delete your Game Capture, then add a new one, don't touch any of the options. If you have a Display Capture in your scene, delete it.

The newest Windows 10 update is 1809(October 2018, not September Kappa), you can force an upgrade by using the Media creation tool or Clicking "Update Now" on this page.

Microsoft will push it to you eventually, there's no escaping

OK works fine, thank you :)
Hope that it also work with other Games like Pubg or Rust.

CPU usage @ Medium is 30-35% on a 2700x, easy peesy. Slow is 50-60%, practically double, Slower is exponentially harder, you will overload immediately. There's not enough cores

720 60 @ Slow was 35% CPU usage for me .
Now I can also stream @ 1080 60 fast (maybe medium is also possible)

But when I use Slower -> Overload but anyway 35% Usage+
I think its not possible to hit more, i dont know

Click to expand...

I should have said CPU usage depends on the source you are encoding. League is lower motion that FPS games, so it is easier to encode.

Beyond Medium 720p60 you will be hard pressed to find any noticable improvement in quality. It is there, if you look really hard, frame by frame, but it is pointless. If you don't skip at Slow, perfect, you've pushed quality as high as possible on the CPU

You could probably do 720p30 Slower, it's a encoding latency issue. Theres not enough threads to finish in time, but if you increase the time available, you can do it.

I just tested it in Sandstorm, it works, looks great @ 6000Kbps. Not a single compression artifact, but it's 30FPS so it isn't great to watch
