Question / Help OBS frames low but CPU usage only 50%

[Mads Thagaard Pedersen]

Hey I got this problem with OBS when i try stream a game, the FPS is horible, it drops down to 16-24 FPS, The problem is it is only using around 50% of my CPU that means there is a bunch more power it can use so it dont have to be that low FPS.

I am using a I7 4770K
32 gb ram 1800 hz
780 ti
windows 10 pro
500 mbit up/down

I am clueless to what the hell the problem is.

even games that are 20 years old have area's that just drops frames for no reason what so ever.

I have tried to lower the bitrate, i have tried to speed up the encoding, i have tried to downscale it to 720p ( no i wont go further down) Nothing seems to work. The use of my CPU ofc. changes but the output FPS does not. It say 0% dropped frames. But the output framerate is just bad, and it is the whole OBS that lags not just the stream. I am simply clueless to what the hell is going on.

Before people ask about my GPU it is not overloading, as i am monitoring both GPU CPU RAM SWAP, Upload And download, and none of those are capped out.

You're overloading your video card.

You're also using display and game capture sources in the same scene, you should not.

You should also be avoiding using display capture entirely as the other capture methods are more efficient.

use vsync to cap fps to 60 and prevent maxing gpu
check "TLDR setup" checklist in my signature for more detailed instructions

Nope I am not, If i where overloading my video card my game would suffer also, It is not.

I am using gsync, and vsync would just throw it up at 144 FPS.

then dont ask if you know better, good luck

Wow, well i can tell you that your sugestions did not work one bit. If you get angry when people tells you that it does not work, then you shouldnt be on a support page m8.

Your own log is saying you ARE overloading your video card.

13:22:38.970: Output 'simple_stream': Number of lagged frames due to rendering lag/stalls: 6199 (24.7%)

That might be but gpu-z says i am running at 80-90. You understand why i am frustrated?

 

[Mads Thagaard Pedersen]

well if it is a gpu problem, then I will see in a weeks time, where my new 1080ti is comming. But i highly doubt that is the case, For godnes sake some of the games i had this problem with is more than 20 years old.

I can easily overload a 1080 with half-life 1 if i really want to...

And what pci-e mode is your card running in? (Screenshot of the first tab of gpu-z)

That was why I lowered everything down to the bare minimum for a watchable stream. 720p 30 fps 3500 bitrate.

PCIe x 16.3.0 @ 16.3.0

Is there any chance you can get a more complete log? Unfortunately the one you posted originally did not include the profiling information, which could be useful here.

You should be able to get this from one of your previous logs, as long as you don't upload the "current" log.

It is the full log. I can try upload a log from yeasterday though, although it is not as bad as the one today. The frames from this log fixed itself after i limited it to 30 FPS. I think it is that log atleast :D

Maybe the downscaling takes too much?
Scaling generally costs a lot of performance.

I noticed that you're on the Windows 10 Creator's Update. Have you tried disabling Game Mode? Game Mode is known to cause performance issues with OBS. https://www.windowscentral.com/how-enable-disable-game-mode-windows-10-creators-update

 

[Mads Thagaard Pedersen]

Thank you I will try that. Now that you mention it, it did start after the creator update. I will take a look if this helps.

Yes that defently worked, now i am able to stream the game in 1600x900 48 fps 6000 bit on ultra with all addons instaled. Thank you so much for the help.

Seems to be an interesting operating system. A gaming mode not suitable for gaming xD
Thank god I'm still on Windows 7.
