OBS uses the best open source video encoding library available, x264 to convert your computerized footage into an encrusted form that can be watched on all platforms. However, some people might experience high CPU utilization and other programs running on their system may also slow down when active if you have settings too high for your hardware which will cause videos or freeze after

Downscale Your Output Resolution
Encoding at a higher resolution will cause your video to take up more space on the computer, but it also means that you are encoding less of an entire scene. For example, 1080p contains over twice as many pixels per frame as 720 does and this can lead to increased CPU usage if not taken into consideration during conversion (downscaling). To help combat these problems OBS shrinks scenes before they’re even sent off for compression–this way we make sure there’s always enough footage leftover after scaling down so our encoder doesn’t get bogged down with big images like those found in high definition videos!
The best way to reduce the resolution of your video is by using one of three downscale filters. Bilinear scaling takes only a few resources, but it will result in an image that has less detail and looks pixelated when playing back on devices without high-end graphics cards; bicubic filtering produces smoother output than liners while still providing better visual quality–it also requires slightly more processing power (so use this if you have good hardware); Lanczos provides even higher levels f computing power with increased memory requirements but offers superb visuals at little extra expense
Lower Your Frame Rate
If you’re streaming above 30 FPS, consider lowering your frame rate. The CPU will have to process less data with each second of footage and this can lead towards lower usage rates on both the graphics card processor as well as processor cores within one’s computer itself! You may even find yourself at 20 – 25fps for those weak-chip computers without much power left in them because there was always some waiting involved before doing anything else besides rendering frames right away.
Change Your X264 Preset
The OBS default setting for the encoder is very fast, which works well with most videos. This can be changed in Settings > Output (check the Enable Advanced Encoder Settings if you’re using Simple mode) and changing to another preset like mblingbing will change how your video looks but use less CPU power during the encoding process!
Try Quick sync, AMF, or NVENC
Quick sync, AMF and NVENC are hardware encoders that come on recent Intel Integrated GPUs, newer AMD GPUs, and Nvidia. You can offload encoding load to those chips at the cost of a somewhat noticeable decrease in quality but they offer greater efficiency than your standard CPU for doing so.. Generally speaking, these GPU based coders don’t quite have as high a level or accuracy compared with x264 but it’s better not only does this mean less strain being placed upside down by your computer processing unit (CPU), you may find yourself saving money too!
Upgrade Your Hardware
Some CPUs are so weak that they can barely break even with a 360p stream at 25 FPS using the ultrafast preset. If you have an Intel i5 or newer, then your computer should be able to do better than this! The same goes for AMD APUs and their 6-core/8 core processors – these will give gamers more of what really matters: power graphics performance in today’s demanding games without sacrificing frame rates on lower settings
Other Programs/games Use CPU Too
One of the most frustrating things about streaming is when a game takes up all your computer’s resources. If you’re playing games like Battlefield or emulators, make sure to keep OBS running in case it interferes with those programs as well! To fix this problem on Windows 10 devices (and newer), use Settings > Process Priority and set “Above normal” for obs if needed
It might sound silly but setting process priority may solve some frustration issues while using different types of software at once- especially since we want our video editor foremost during session time.
