Lowering the sample rate can help reduce CPU usage without significantly impacting audio quality.
Also, avoid unnecessarily high channel configurations if you dont require them.
If your system supports hardware encoding, opt for it as it relieves the CPUs load.
you’re free to find encoder controls in the Output tab, under the streaming and recording sections.
Advanced controls:OBS provides additional advanced controls that can further optimize CPU usage.
Profile prefs:OBS allows you to create and switch between different profiles.
Consider creating and using a profile specifically dedicated to streaming with optimized prefs.
This ensures that each time you stream, the optimized parameters are automatically applied, minimizing CPU usage.
Remember, the goal is to find the right balance between performance and quality.
Its a continuous process of fine-tuning and adjusting options based on your specific streaming requirements and hardware capabilities.
Here are some steps you could take to lower the video resolution in OBS:
1.
Determine the optimal resolution:Analyze your streaming needs and audience preferences to determine the appropriate resolution.
Reduce the resolution value to your desired lower resolution.
This setting defines the resolution at which OBS captures your content.
Downscale the output resolution:In the same Video tab, find the Output (Scaled) Resolution section.
Set this value to the desired lower resolution.
OBS will downscale the captured content to this resolution before encoding and broadcasting it.
Lowering the video resolution can significantly reduce CPU usage, especially when combined with other optimization techniques.
The frame rate refers to the number of frames per second (fps) displayed in your stream.
Lowering the frame rate can lighten the CPU workload, resulting in improved performance and reduced CPU usage.
Here are some steps to adjust the frame rate in OBS:
1.
Determine the optimal frame rate:Consider your streaming content and target audience when deciding on the frame rate.
Standard options include 30 fps and 60 fps.
Select your desired frame rate from the dropdown menu.
Alternatively, you’ve got the option to manually enter a custom frame rate if desired.
Lowering the frame rate reduces the CPU workload required for encoding and transmission.
Consider the nature of your content and the preferences of your viewers when deciding on the optimal frame rate.
This can significantly reduce the CPU workload and improve overall performance.
Here are the steps to utilize hardware encoding in OBS:
1.
Determine GPU compatibility:peek if your graphics card supports hardware encoding.
Most modern GPUs from NVIDIA (NVENC) and AMD (VCE) offer hardware encoding capabilities.
Visit the manufacturers website or consult the cards specifications to verify compatibility.
This ensures OBS uses the GPU for encoding rather than the CPU.
you could experiment with these options to find the optimal balance between CPU usage and stream quality.
Utilizing hardware encoding can significantly reduce CPU usage, allowing for smoother performance and improved system stability during streaming.
Keep in mind that the quality of hardware-encoded video may differ from CPU-encoded video.
However, modern hardware encoders offer impressive performance and quality.
Each source and filter applied in OBS requires CPU resources to process and render.
Here are some steps to limit the number of sources and filters in OBS:
1.
Remove any sources that are not actively contributing to your stream or recording.
Simplifying the scene composition will reduce the CPU load and improve performance.
Prioritize necessary sources:Determine the essential sources that you require for your stream.
Remove any sources that dont add value or are seldom utilized.
Focus on the most relevant sources to reduce CPU usage while maintaining the desired visual experience.
Review and refine the filters applied to sources to ensure they are necessary and efficiently implemented.
Remove any filters that are not vital to your stream.
Certain sources, like images or internet tool sources, can often be more resource-intensive than others.
Additionally, choose filters that have minimal impact on CPU usage while still achieving your desired visual effects.
Observe the changes in CPU usage and stream quality to ensure the desired improvements in performance have been achieved.
Remember to strike a balance between optimizing CPU usage and maintaining the desired visual quality of your stream.
Identify any features that are not essential to your streaming needs or are seldom utilized.
Disable visual effects:OBS provides various visual effects and transitions for scene switching and source animations.
Evaluate whether using effects like fade transitions or animated overlays are necessary for your stream.
Disabling these effects can reduce CPU usage, especially during scene transitions.
Unnecessary plugins can consume CPU resources even when not actively used.
Evaluate whether these features are crucial to your stream and disable them if theyre not needed.
Temporarily disabling these features can helpimprove CPU performance.
Observe the changes in CPU usage and stream quality to ensure the desired improvements in performance have been achieved.
