Sony surprised everyone today by quietly launching a PS5 Remote Play app for the PS4, and with it, opened the way to stream PS5 games to the current-gen console.
As VGC reports, in order for the Remote Play app to work, both a PS4 and PS5 console need to be owned. The two consoles can then be connected via a home network. First, the Remote Play feature must be enabled on the PS5 before the PS4 can locate it on the network. This can either be achieved automatically or by entering a code.
Once connected, it will be possible to stream a game running on the PS5 to the PS4 and control it as if it's running on the PS4. This means you can play PS5 games in a different room and control those games with a DualShock 4 controller, although you'll be missing out on the enhanced level of feedback offered by the PS5's DualSense controller.
Ultimately, the best place to play PS5 games is on a PS5, but Remote Play is a nice option to have if for some reason the room where the PS5 is located can't be used. As to how well the streaming works, we'll have to wait until PS5 launch day to find out. This isn't a new feature Sony is introducing, though. Remote Play was made available for the PS3 and PS4, allowing game streaming to PSP, PS Vita, PlayStation TV, Xperia smartphones, tablets, and even Windows and macOS machines.
