Question / Help High CPU usage/Spikes when streaming

Lostmyrag · Oct 29, 2013

Hi guys, Wondering if you can help, i have looked everywhere for a solution, my Hardware has managed to stream no problem before and now it has been slowing down to 1 FPS when a Spike in the CPU usage for OBS occurs, I have had Task manger open with resource monitor open and OBS generally sits at 10-15 CPU usage on my 8350 CPU, when it spikes the % goes up to around 35 making anything i play unbearable to play/stream.

I have tried Game Capture and my live gamer HD in a single PC set up. help!

Heres a log.

(use code tags around log data if possible - jim)

Hm, don't see anything particularly wrong, though do you have both game capture and dxtory active at the same time? That would be bad. That log is a bit confusing.

Lostmyrag · Oct 30, 2013

Yeah, i thought it was a long log.

basically Dxtory has been set up as a scene but i dont use the program at all, Dxtory isnt even running. This has been the same set up ive been using for months. does 200,000kb in the process tab seem like enough CPU take up or is it about right?

I have also tried reinstalling OBS and wiping all scenes, starting from scratch. gahhh

Cheers

Well your CPU is great, and you're not particularly encoding a high resolution/fps, so it really shouldn't be spiking. If it is, I would recommend getting rid of any excess things in your scenes that are not needed. The only real thing using CPU in OBS is the encoder, and I didn't make the encoder. The encoder is the top h264 encoder out there, and most widely used, so I can't help but feel that the issue would have to be something else in this case, maybe outside interference of some sort? I'm not entirely sure. All I can tell you is this does not happen under normal circumstances.

Thanks Jim,

Im looking into all sorts of eventualities. Starting to sadden me slightly!

Just out of curiosity, How much CPU Memory should OBS use, i know it may depend on what settings you are using etc, But with mine, I check the Task manager and iunder processes, OBS takes up 200,00k, Also i have noticed that in the resource monitor under the PERFORMANCE tab, OBS is jumping up from 10 to 40% causing the spike.

Does that sound about right?

Thanks JIm.

200-400 megabytes isn't uncommon. It depends on what you have in your scene and such. There's a lot of data that has to be buffered for the stream.

40% CPU usage doesn't sound too unusual, though maybe it's higher than it should be for 540p resolution. if it were nearing 100% it would be a concern, and at that point I'd probably be suspecting some sort of CPU throttling, or just generally some sort of outside interference. You might want to go into the chat some time and ask the humble denizens there about it as some of them are a bit more knowledgeable about than than I
