Since these steps are for Nvidia users, the name or path will vary in the AMD Catalyst software panel for Radeon GPU users.

Choose High-performance NVIDIA processor from the context menu.

Click on the drop-down menu for Select the preferred graphics processor for the program:.

Find and select OBS Studio(bin/64bit/obs64.exe).

Expand the drop-down menu to Select a program to customize:.

Open Nvidia Control Panel and click on Manage 3D settings.

Do the same for the Encoder option from the Recording section.įurthermore, ensure you’re using the dedicated GPU(Nvidia/AMD) to run the OBS application.įollow these steps to run OBS with a dedicated GPU:.

If you have an Nvidia GPU that supports NVENC codec, select Hardware(NVENC, HEVC) or Hardware(NVENC, AV1). Expand the drop-down menu for Encoder in the Streaming section.Go to OBS’s Settings and click on the Output tab.Here’s how to use hardware accelerated encoder on OBS: This is why using a dedicated GPU & hardware-accelerated encoder to run OBS is an ideal solution to get rid of OBS’s high CPU usage while streaming. These encoders use GPU hardware acceleration to render a given task much faster, hence requiring a lot less CPU usage. Hardware encoders such as NVENC, AV1, etc are much more efficient than typical x264 software encoder. Read our troubleshooting and fix it instantly for your Windows 10. Many users face high usage with WMI Provider Host without any reason. But it will ensure that everything runs smoothly and resolve any abnormally high resource usage issues. Select a lower FPS value(like 24 or 30).Ĭapturing the screen at lower fps might not offer as smooth of a video as 60fps or higher.Expand the drop-down menu for Common FPS Values.Here are the steps to lower the framerate for OBS recording: In such a case, lower the capture FPS to 24 or 30 to reduce the rendering load, thus effectively lowering the overall CPU utilization by the app. If you’re recording at a higher FPS and often seeing Encoding overload notifications on your screen, then your system clearly can’t handle the rendering load. Lower FPS for RecordingĬapturing more frames per second has a huge impact on the overall processor utilization by OBS. If you are constantly getting high CPU usage with System Interrupts, check our separate article and follow along with the fixes to solve this issue. But it should not use all your CPU resources. System Interrupts help Windows to communicate with the Hardware devices. You can also downscale various capture filters to further reduce the rendering pressure from the CPU. Keep in mind, the output quality of your video might downgrade due to lower capture resolution. Click on the drop-down menu for Output (Scaled) Resolution and select a lower resolution.Launch the OBS application and click on Settings from the bottom right corner of the screen.

This is one of the main reasons why you might encounter error notifications such as Encoding overload or high CPU usage in OBS.įollow these steps to scale down the output resolution in OBS: Why? Because encoding higher resolution equals a higher processing load. Since the OBS records the screen in real time, the program’s CPU usage will rise based on the recording resolution. Here’s how to reduce OBS’s CPU usage on Windows 10/11/Mac: 1. Read on as I have thoroughly discussed all these methods, along with some additional ones, which can resolve this issue in no time. You can also try other solutions, such as lowering the framerate, customizing the x264 preset, etc.

For example, downscaling the output resolution of screen recording can effectively reduce OBS’s CPU utilization by a lot. The main reason for OBS’s high CPU usage is misconfigured OBS settings. Check the Video Source & Lower OBS Processing Priority
