If your desktop audio runs at 44100 Hz but you have OBS set to encode at 48000 Hz, it will have to resample the audio, which uses CPU time. The more audio sources you add (eg Microphone, Media Sources) that use different sample rates, the more CPU usage will be consumed by resampling.

Keeping this in consideration, how do I fix high CPU usage OBS?

The most common way to reduce CPU usage is to downscale your resolution. When you downscale, OBS takes your scene and shrinks it as much as you tell it to before giving it to the encoder.

One may also ask, how do I fix too much CPU usage? Let's go over the steps on how to fix high CPU usage in Windows* 10.

1. Reboot. First step: save your work and restart your PC.
2. End or Restart Processes. Open the Task Manager (CTRL+SHIFT+ESCAPE).
3. Update Drivers.
4. Scan for Malware.
5. Power Options.
6. Find Specific Guidance Online.
7. Reinstalling Windows.

Also Know, how do I reduce CPU usage in OBS?

Here are some ways you can reduce resource utilization and, hopefully, make both OBS and your programs run faster while encoding:

1. Downscale your output resolution.
2. Lower your frame rate.
3. Change your x264 preset.
4. Try Quicksync, AMF, or NVENC.
5. Check your sources.
6. Upgrade your hardware.

Why does my CPU run so high?

High CPU usage can be indicative of several different problems. A maxed-out CPU is also a sign of a virus or adware infection, which should be addressed immediately. It could also simply mean that your computer can't keep up with what you want to do, and an upgrade may be in order.

Does streaming and recording use more CPU?

Recording only uses more cpu than streaming if you're using more cpu-intensive settings for recording.

Does a capture card reduce CPU usage?

CPU usage goes down because with a capture card, the encoding is done on an entirely separate computer. The gaming computer only has to run the game, not encode the video. If you're using the capture card in the same computer you're playing the game on, you're doing it wrong.

Is quick sync better than x264?

x264 veryfast will give close or a bit better to H264 Haswell Quicksync quality. x264 at ultrafast-superfast can be worse than Quicksync3. But that depend on what version of Quicksync are you using too. Sandy Bridge and Ivy bridge has lower quality H264 Quicksync while Haswell+ has better quality.

Why does Streamlabs use so much CPU?

The top reasons for high CPU usage are: outdated GPU drivers, animated overlays, fullscreen browser sources, x264 encoding, monitors/displays plugged into the motherboard & not the GPU.

Does Streamlabs OBS use more CPU?

Just check the box 'Use optimized encoder settings' before going live with Streamlabs OBS. So what is this all about? All existing video codecs use algorithms that provide a decent video quality. Extensive testing has shown better video quality and lower CPU usages in most cases.

Does OBS use CPU or GPU?

In particular, NVENC on the NVIDIA 10-series GPUs is currently better than any Quick Sync (Intel) or AMF capable (AMD) product. Additionally, OBS also requires some CPU resources to be running, just like any other app. The more sources you have, the more CPU it will require.

What does CPU usage preset do OBS?

Change the CPU Usage Preset

The usage preset refers to how fast the CPU encodes video. The faster it encodes, the less CPU it uses. By default, this is set to “Very Fast”, which provides the best balance between performance and quality.

What is the best rate control for OBS?

If you're streaming, use CBR as every platform recommends it and it's a reliable form of Rate Control. If you're recording and need to be high quality, use CQP if the file size is no issue, or VBR if you want to keep file size more reasonable.

What streaming software uses the least CPU?

OBS

Does Bitrate affect CPU?

Bitrate does have an influence on cpu, since you basically convert more data per second. But it's pretty minor even on lower end cpu's unless you go for extremes (in the 100000's). Preset, resolution and fps are of a much bigger influence on your processor.

Which is better OBS or Streamlabs?

Streamlabs OBS is ultimately an advancement of OBS with increased functionality. Streamlabs OBS is essentially the same OBS code revamped with a better user experience. This software is also free and offers an even easier installation process than OBS.

Which uses less CPU OBS or Streamlabs?

With the simple interface, OBS Studio usually boasts a lower CPU usage while streaming. OBS Studio is also the parent to most of the other alterations of the program, such as OBS Live and Streamlabs OBS.

Is x264 better than Nvenc?

NVENC is NVIDIA's encoder. NVENC in the GTX 10-series GPUs provides superior quality than x264 Very Fast, the most commonly used x264 preset. And in the new RTX 20-series, NVENC performs better than x264 Fast and on par with x264 Medium, a preset that requires an expensive dual PC setup.
