Tryed to stream League of Legends yesterday on highest possible settings.
Fresh Windows 10 insider preview build 10162.
Latest OBS. Latest Nvidia driver, 353.30.
Hardware:
i7 5820k @ 4,5GHz
GTX 970
16GB DDR4
Anything else is pretty good too. No overheating, was monitoring temps during the stream.
Settings: 1080p 60FPS veryfast preset (was able to stream with faster preset on windows 8.1 before with the same CPU load!).

First - the CPU load from OBS is higher than under Windows 8.1 with same settings!
Second - Task Manager shows a different CPU load than other tools loke Core Temp and CAM software.
Third - my FPS ingame jumped around, way lower than they should be.
And the last problem - somehow the Chrome CPU load was over 30% (in the Task Manager) with just my stream and some pages without flash open, so what the heck is going on?

P.S. Yes i know - never touch a running system blah blah. I know that Windows 10 is a beta right now with a shit ton of bugs and other interesting things... Still, it should work.

Here is the logfile from that stream:

Lower the webcam resolution to something reasonable and using monitor capture isn't the most optimal way to capture a game. Try game capture.
 
Monitor capture was off, its just avaliable in the list. I use the window capture for both, the 2d and 3d client in LoL while playing in borderless mode.
The webcam resolution is the native one and why the heck would i change it, i had no problems running it at the native resolution and thousand of other people streaming with the same c920 dont complain.
My main problem is the performance difference between the win8.1 and win10 with the same hardware and same settings. How can i fix it? And yes i want to use windows 10 from now on and the ssd with win 8.1 will be just a backup system in case something goes really wrong.
 
Yeah i tryed all the stuff, its not my first day streaming. The rig is running perfect, just now with Windows10 i have some strange things going on here and there.
Game capture works only with the 3D-client, but LoL also has a 2D client with integrated browser, youtube etc. This cant be captured by game capture, so its either monitor capture or window capture.

And its also not about the game. Even when the game is not running, somehow the OBS performance is way lower than what i was squeezing out of it while using Windows 8.1 - so what the heck is going on? My rig is more than capable for anything that i can throw at it, so what is it?
 
I've started using Windows 10 RTM and there are some performance issues with OBS Multiplatform. Getting big frame drops. In windows 8.1 that was not a problem.
 
We need a fix right now, the official release is in 10 days if they dont delay it.
Specially for the old OBS, because OBS MP is pretty far away from being a full replacement for the old one.

In 10 days, the majority of broadcasters will still be on windows 7. Even w/ it being free I wouldnt dare upgrade day 1, and if I did it would be as a secondary O.S. Stop freaking out, windows 10 support will be there sooner than a lot of the stuff we'd like to have.
 
I'd like to know how many windows 10 adopters have actually done a clean install with a formatted drive? How many non beta drivers are with windows 10 support? All of these factors matter, just because it worked on 8.1 does not mean it will work the same or at all on Windows 10.

Don't hold your breath, something like this needs to be reproduced, then a cause has to be found which then has to be fixed and tested. It's not like there is an army of developers behind OBS.

Also who knows if it isn't a problem with the Windows 10 nvidia drivers? Something basic as mouse cursors was broken in the 353.50 driver version. Or mayb there is a problem in some other driver?

So it's not an easy thing to "fix".

Well we are willing to help, provide logs and information to make it work.
I know that the team behind OBS is pretty small, nobody has thousands on manhours instantly avaliable to work around something that was not expected. No idea how small the team is, but i expect less then 10 people working part-time on the project, maybe a couple of guys working fulltime.
But i expected this to be the major issue right now, where everything else is paused until the core functions (maintaining FPS while recording/streaming) are working with the new OS.
Anyway, need help reproducing the issue? I`m not a coder, but can provide FPS numbers, logs, all the background data like driver versions etc.
 
OBS (and OBS-mp) is basically done by 1 person in his own time, there are several ppl who have contributed certain parts also in their own free time, this is how most open source projects work. It's quite impossible to focus solely on performance issues that may or may not be caused by OBS itself, especially on a OS that's not even released yet.
But obviously any data will help, especially logs from streaming/recording sessions on Windows 8 and from Windows 10, so we can compare certain settings and cpu/gpu profiler results.

Also regarding your point about chrome using more cpu, I have seen this exact behaviour too. Sometimes it's just using below 10% and suddenly it is using 40-50%.

Well i can try to record some games, slap the task manager/resource monitor into the scene and do some recordings, mostly in games with a built in fps counter (to avoid the hook conflict issue while using third party tools).
