This number will be used for the plugin per load balance operation cpu limit, which uses smp-cpus to stripe your data. It does not affect the number of cpus used in any other \CGG{} operation besides plugins. On large cpu systems, it can come in handy to downgrade the number of cpus used for some plugins; otherwise it uses all of the processors and splits up the program into too many pieces which may add

+ \item[Use HW Device] \index{HW Device} \CGG{} can use hardware timeline acceleration (decoding) via GPUs thanks to the \textit{OpenGL} video driver. By default the \textit{X11} video driver is used, which works only with the CPU. See \nameref{sub:video_out_section}. For h264, h265 (HEVC) and VP9 codecs you can use libraries specific to AMD, Nvidia and Intel graphics cards. For AMD and Intel set \textbf{vaapi}; for Nvidia set \textbf{vdpau} (also works with AMD thanks to a wrapper). \textbf{Cuda} does not accelerate decoding with Nvidia, but it does allow some plugins to run that are not available otherwise. \textbf{None} (default) uses the video driver set in the \texttt{Playback A/B} tab.
