OBS is an open source video editing program that uses x264 to encode your videos. However, you might experience high CPU utilization and other programs running on your computer might suffer while it’s active if the settings are too much for what hardware can handle- in some cases OBS will say “Encoding overloaded!” This means there isn’t enough time or space allotted towards encoding tasks which leads up to frozen videos because they take longer than expected due solely by how elaborate their setting options get without any change being made within them personally so make sure before starting anything important with this software whether or not its compatible with all aspects of PC performance based off these
Downscale your output resolution
The resolution you are encoding at has the biggest impact on CPU usage. For example, 1080p contains more than twice as many pixels per frame versus 720 and your computer’s performance increases accordingly; however this could lead to an un-downscaled video file that may not be able for some devices with low RAM or lower end graphics cards like integrated Intel HD 4000 (just because they don’t have extremely high specifications). To reduce these strainers during compression time OBS will take your scene in its original form before down sampling it which helps save memory while still providing good quality output videos so users get their money worth out of what they spent
Want to get a better performance out of your website? You can change how much you want to downscale in Settings > Video and Output (Scaled) Resolution. Keeping the Base resolution same will ensure that everything stays crisp, while still being able scale back up when needed for smoother scrolling or video playback on mobile devices!
The different downscale filters (bilinear, bicubic and Lanczos) all have their own unique properties that can be seen when computing the image. Bilinear is faster but doesn’t look as good while LancZos takes more resources with better results in regards to quality for a given bitrate used during compression process. Feel free experiment which filter works best for you!
Lower your frame rate
You can also reduce the number of frames your CPU has to process with a lower frame rate. For example, if you’re going above 30 FPS and notice that it’s slowing down memory access speeds on a weaker graphics card or processor for some reason then consider lowering down as low as possible without sacrificing video quality (which should still look fluid).
Change your x264 preset
There are a number of “presets” that you can use to change your video quality and CPU usage. The default, OBS fast setting for x264 is tuned just right: optimized enough not to slow down proceedings but without sacrificing too much on either end! You may want to experiment with these presets if something isn’t looking quite right or maybe even try out some different things entirely by changing settings in Settings > Output (check Enable Advanced Encoder Settings > Encoder Preset.
There is a huge difference between setting your desired Clock Speed and the actual clock speed that shows up in-game. For example, even one step faster or slower can have an effect on how much processor usage you experience with Fallout 4’s preset system. To find out which option works best for your computer be sure to try them all!
Try Quicksync, AMF, or NVENC
NVENC and AMF are hardware encoders that come on recent Intel Integrated GPUs, newer AMD GPUs. You can offload encoding load to those powerful devices at the cost of a somewhat noticeable decrease in quality for your video files but they offer an immense advantage: significantly lower CPU usage when compared with x264-based software alternatives!
Check your sources
You may have noticed that your computer is running slower when you use a camera. This could be because the device uses up all of its processing power, which can make things laggy for other programs on Chrome or Firefox browsers while they’re hooked in with their lenses open. To fix this problem (or avoid it), try adjusting how often these webcams generate frames per second by monitoring settings like resolution and framerate before opening any videos; also keep an eye out if there are complex animations happening!
