This will force OBS to output at a constant frame rate, duplicating frames if necessary to achieve this. Setting it to 'faster', 'fast', and below is generally not recommended and does not improve quality enough to where the increased CPU usage is justifiable. If you have a slower CPU or a CPU with two or fewer cores, sometimes using 'superfast' and 'ultrafast' are recommended in order to further reduce CPU usage, though at the cost of quality. Generally, the best setting is 'veryfast', as it arguable gives the best tradeoff between CPU usage and quality. Settings this to a slower/lower value means the encoder will use more CPU to try to improve quality, setting this to a faster/higher will cut certain quality features in order to reduce CPU usage. This setting determines how much CPU you want the video encoder (selected in your encoding settings) to dedicate for encoding. x264 CPU Preset / Quicksync Preset / Nvenc Preset

This setting completely de-activates the encoder while a preview is running to lower the cpu consumption.Īctivates the use of several modifier keys to be used as hotkeys. Lowering the value can lead to audio and synchronisation problems. Only change this value if you know what you are doing. Sets the amount of milliseconds the scene is buffered before being sent to the encoder. As encoding can consume a lot of CPU, setting this to say 'above normal' can sometimes be useful to ensure capturing and encoding is done in a more timely fashion. There's almost no need to ever turn this off.

This will use multiple threads for color space conversion, maximizing benefit from multi-core CPUs.

You can very easily end up with a bad quality stream, throughput problems or excessive CPU usage by changing these settings. Changing advanced options should never be done unless you fully understand what you are doing.
