when downloading media, remuxing and transcoding will be done on-device instead of the cloud. you'll see detailed progress in the processing queue. disabled: local processing will not be used. processing instances can enforce local processing, so this option may not have effect. preferred: media that requires extra processing will be downloaded through the processing queue, but the rest of media will be downloaded by your browser's download manager. forced: all media will always be proxied and downloaded through the processing queue. exclusive on-device features are not affected by this setting, they always run locally.
