Graphics card

This PC is also used for games. Guardian gives the card back when the room is quiet, and steps aside when something else needs it.

How Guardian uses the GPU Release after 120 s of quiet Reloading takes about 3 seconds and only delays a transcript — the audio is already held in memory and in the archive. Step aside when another app needs the GPU
