This is the best summary I could come up with:
PlayStation 5 beta firmware includes game streaming from our catalog with up to 4K resolution only for PS Plus Premium subscribers.
This update includes Dolby Atmos, more accessibility or simple curiosities such as the possibility of deactivating the initial beep, and now incorporated a feature that had been announced in June: the game in the cloud with PS5 titles.
“When it launches, cloud play with compatible PS5 games will be playable directly on your console,” Sony said in its announcement.
“This means that as a Premium user it will be easier for you to jump into your favorite games without downloading them to PS5 first.”
Sony had announced some “aggressive” plans for its game in the cloud: “We see that mobility in gaming habits is an increasingly important trend, and the cloud will be essential to allow us, or indeed anyone else, to exploit that trend,” said Jim Ryan, head of PlayStation.
One of the initiatives that Sony presented is Project Q, a laptop exclusively designed for remote play from a PS5.
