    Minimizing CPU/GPU workload to stream and record at the same time

    Hi There, I am looking to stream and record at the same time so I can keep the higher quality files, but also not have to double the work load. My understanding is if you mirror your stream and recording settings this is possible. I have setup mine like this, would someone mind taking a look...

    High CPU and Audio Distortion

    Hey, I'm working on setting up presentations we can present to customers and will be using OBS primarily over Zoom, or another Webinar option I'm still researching. My test runs have not gone well, my CPU is getting throttled to 100% and the audio coming in from others and going out is really...

    CPU bottleneck with NVENC

    I streamed Spider-Man and Horizon Zero Dawn this week and even though I'm using the Nvenc encoder and OBS was utilizing less than 10% of the CPU, I was getting way lower FPS in these games than I should. I noticed that the GPU was being missvely under utilized. It concerns me a lot since it's...

    -'kernel_task' climbs to 1000% CPU after a few minutes of opening OBS-

    here is my most recent log file --> https://obsproject.com/logs/lsFswxivH3Mt81Xl (the analysis didn't detect any problems) every time i open OBS, a 'kernel_task' starts eating up CPU according to 'activity monitor'...approaching 1000% and rendering my computer unusable until i quit OBS i'm...

    Question: is it possible to use both GPU and CPU for recording?

    I can record at native resolution (1080p) with my gpu but i ask myself if it is possible to split the recording task between the cpu and gpu? I have a low-middle end pc so it would be helpfull. Thank you in advance.

    CPU encoding causing crashes.

    Hey everyone, I was having trouble for the past few streams where I was mid-stream and suddenly OBS would crash. At first, I didn't know what this issue was but I managed to discover it and it was something to do with the CPU encoding. This is a really strange issue as I haven't had these...

    High CPU Usage Since Update to 27.2.1

    I've noticed today that all my games are lagging as I am streaming where it never did it before. So I opened up task manager and now since the update OBS is using 60+% cpu whereas it only used 20% avg with my current settings. Now its 40% higher. And now it's barely using any gpu which before it...

    CPU usage: Browser source better than local file?

    Hello there, I'm trying to optimize my cpu load (older cpu) while streaming. I watched some videos where they say, that it's better to use browser sources instead of local files. But how does that make sense? The browser source must be rendered like everything else right? Or is it about...

    H264 or x264?

    Hey dear, Open Broadcasting Software forum! Today I changed to H264/AVC Encoder (AMD Advanced Media Framework) which was before on "veryfast" x264.. I also did experiments on medium up to ultrafast (ultrafast is too extremely pixelated, and medium is not pixelated, and in realities like "The...

    Why OBS is using a significant amount of CPU when using NVENC?

    From my understanding, the composition of the different sources is done on the GPU and it's also the case for the encoding (NVENC) so what is left on the CPU? I have a CPU bottleneck so I would like to know how I can influence the CPU consumption of OBS knowing I'm using NVENC encoding

    Does streaming and recording at the same time use more CPU when using NVENC?

    using recording quality same as stream or different quality. Is it just asking more work to the encoder (on the GPU) or is it doing more work on the CPU too?

    95% CPU usage on MAC with Elgato HD60s+

    Hi, I am running into this horrible overload of CPU usage on my 2016 MacBook Pro 13". As I have been trying to fix it for over two weeks I will try to narrow down the issue: Whenever I start up OBS it completely clogs up my Mac's CPU, averaging between 87-95% (even when idle). I recently...

    Highly random CPU usage (online&offline)

    Hi all ! I recently restored a clean version of my streaming PC. Since then I'm getting high CPU usage on a random basis. Let me explain : Sometimes I spend hours livestreaming (NVENC) + recording (x264) without a hitch. Sometimes I just boot up OBS, not even going live, to find my usual 10%...
