Question / Help FPS is dropping

[zappy1000]

I haven't had this issue in awhile, but it was never this bad. when sometimes even when my cpu is using like 30% i'm still dropping fps while streaming i've lowered the preset to ultra fast and changed bit rate and it will still do it when I swap games sometimes etc. I used to have it at 60fps 2600 bitrate and very fast with no issue so I'm not sure what happened. Those are the three logs from today. Please help me the only way I fix this is by stopping my stream and either restarting OBS or restarting my PC.

You've got a little bit of everything.

The rendering lag is GPU overload. Most of the logs show a bit of it, one entry shows significant (8.5%). Getting rid of this means making sure your game doesn't monopolize the GPU so that OBS can render frames. This is usually done by capping the in-game framerate, reducing the capture resolution, or adjusting other quality settings.

Well I have a 1080 Ti, but I always cap FPS and normally run low graphics all the time so I dont know.

Unplug your webcam then test again.

I don't think this is GPU usage but instead Video Capture Device lagging the render.

You have both Render and Encoding lag, at 720p48 Super Fast with a 7700K and 1080Ti playing LoL, this shouldn't be possible unless something else is misbeahaving, and it's usually webcams that do it, that or Browser Sources

Yeah I'll try that for sure I might swap the USB ports because I think this happened before.

 

[zappy1000]

I tried unplugging the webcam and it still wants to act up.

 

[zappy1000]

I even swapped USB ports in this test

It was re-determined recently that Game Mode and League of Legends ...and OBS, do not play well together. Take steps to disable Game Mode on your system or just League of Legends for now by following this link

https://obsproject.com/wiki/How-to-disable-Windows-10-Game-Mode

Game Mode and LoL specifically reduces your systems thread count to 4, and also restricts GPU usage to OBS. This combination causes both Rendering and Encoding lag on even the simplest of settings

 

[zappy1000]

I didn't use league that time I tried battlefield 5 and I tried turning game mode off but there's no switch so I did the regedit thing and created a allow game mode and set it to zero so I would its off. Not sure why I didn't see a switch I'm on the latest windows update.

 

[DEDRICK]

Hit WIndows + i, goto system >About. 1809 is the latest Windows 10

Which gives you this

You can force the update if Microsoft isn't pushing it to you through Windows Update

It's still mostly encoding lag though @ 720p60 Very Fast

22:14:08.968: Video stopped, number of skipped frames due to encoding lag: 2782/9782 (28.4%)

What is your OBS CPU usage when recording/streaming your desktop in the Windows scene, one of yuor browsers sources could be hammering your CPU

You can test this by disabling them or creating a new scene collection and only creating a basic scene (Capture + Webcam) then playing a game. If you don't have issues then you know it is your sources causing this issue

 

[zappy1000]

I stayed at a steady 60fps on my window scene it only like to drop frames when I go and open a game.

OBS is using 18.3 to 17.1 % of my cpu and when I was in BFV last night to test my cpu usage overall was about 70%, but I used to use all 100% or 95% when streaming cod blackout with no issues about 2 months ago.

 

[zappy1000]

I updated and turn off game mode and it still dropped the frames even after lowering the encoder which I know I shouldn't have to do.

 

[zappy1000]

I think these should updated logs with me not having the browser sources on them

 

[DEDRICK]

Something is very wrong here. Create a New Scene Collection, name it whatever. Don't worry, you old collection will still be there under the name Untitled.

Add a Single Game Capture, nothing more

Test your x264 settings playing BFV

 

[zappy1000]

New scene collection I only saw it drop to 59.04 fps for a sec when fully opening BFV.

 

[DEDRICK]

Even with these simple settings you are skipping, not much though.

So it is something with your old Scene Collection, its either goign to be the Webcam settings/resolution or your broswer sources.

You may need to delete your browser sources then re-add them

[zappy1000]

yeah but shouldn't I not even be skipping with that new collection? I've used the same settings for awhile now.

 

[zappy1000]

so I ran it without browser sources and it dropped some fps loading BFV but when I loaded league it was fine without browser sources I still had the camera on though.
