Part 1: Issues When OBS Takes High CPU Usage
When OBS takes high CPU usage, it can cause several issues that can affect the quality of your stream or recording, including:
Dropped Frames: When your CPU is overloaded, your computer may not keep up with encoding the video frames. This can result in dropped frames, which can cause stuttering or freezing in your stream or recording.
Audio and Video Desync: High CPU usage can cause audio and video to become out of sync. This can happen because your computer struggles to encode the video frames quickly, delaying the audio and video.
Poor Performance: When OBS uses many CPU resources, it can cause other programs on your computer to slow down or even crash. This can impact your gaming experience or make using other applications while streaming or recording difficult.
Overheating: High CPU usage can cause your computer's CPU to generate more heat, which can cause your computer to overheat. This can result in performance issues or even damage your hardware if checked.
To prevent these issues, it's essential to monitor your CPU usage while streaming or recording with OBS and take steps to reduce it if necessary. This can include adjusting OBS settings, upgrading your hardware, or using a dedicated streaming PC. And next part will give you solutions to solve the high CPU usage of the OBS problem.
Part 2: 9 Solutions for OBS Occupying High CPU
When OBS uses too much CPU, it can cause issues such as dropped frames, audio/syncing video issues, and poor performance. Here are some potential solutions to fix high CPU usage in OBS:
1. Lower Video Settings: High video settings can increase CPU usage. Try reducing the resolution, frame rate, and bitrate to reduce the load on your CPU.
2. Use Hardware Acceleration: OBS supports hardware acceleration, which uses your computer's GPU to help encode video. To enable hardware acceleration, go to the Encoder menu and click the Hardware (NVENC) or Hardware (QSV) button, depending on your graphics card.
3. Close Unnecessary Programs: If you have other programs running in the background, they can also increase CPU usage. Try closing unnecessary programs to reduce the load on your CPU.
4. Disable Preview: The preview window in OBS can increase CPU usage, especially if you have a high-resolution display. Try disabling the preview to reduce the load on your CPU.
5. Upgrade Hardware: If none of the above solutions work, it might be time to upgrade your hardware. Consider upgrading your CPU or graphics card to improve performance and reduce CPU usage.
6. Adjust the Process Priority: You can adjust the priority of the OBS process to allocate more or fewer CPU resources. To do this, right-click the OBS process in the Task Manager on Windows or Activity Monitor on Mac, and click the Set Priority or Renice button, then choose a priority level.
7. Use a Different Encoder: OBS supports different encoders, including x264, NVENC, and QuickSync. Try using a different encoder to see if it reduces CPU usage. You can change the encoder under the Encoder menu from Settings.
8. Update OBS and Graphics Card Drivers: Ensure you have installed the latest version of OBS and graphics card drivers. Newer versions may have optimizations that improve performance and reduce CPU usage. It is a good choice to record game audio with OBS smoothly, as well as game video.
9. Adjust Bitrate: The bitrate determines how much data is streamed or recorded. Try adjusting the bitrate to reduce CPU usage. Lower bitrates require fewer CPU resources but may result in lower video quality.
Hopefully, one of these solutions will help you lower OBS high CPU usage on Windows and MacBook. It also helps improve your streaming or recording experience.
Part 3: OBS Alternative to Avoid High CPU Usage
If you want to avoid the high CPU usage of OBS on your computer, using an alternative is also a recommended solution. And AnyRec Screen Recorder is a software program to record your computer screen and audio.
