Sony has reportedly begun rolling out a cloud streaming beta for PS Plus Premium subscribers — and it supports up to 4K resolution. Announced in June as being in the “early stages” of development, the feature will support PS Plus catalog titles, game trials and “supported digital PS5 titles that players own.” The feature could help PlayStation owners avoid lengthy downloads that take up precious storage.

An alleged PlayStation email to an invited tester, posted on Reddit, reads, “We’re excited to unveil PS5 cloud streaming, and your help testing it means a lot to us.” The beta period uses exclusive invite codes that can’t be shared with other users. The email notes that features could change before cloud streaming’s official launch.

User ArashiGames wrote on ResetEra that they tested God of War: Ragnarok at 2160p with “no issues so far.” They described resolution options ranging from 720p to 2160p for that title, and they said Returnal streamed in 4K. “There’s a new section in the PS+ menu that is for Streaming PS5 Games,” the beta-tester wrote. “Just click the game and it loads in a few seconds.” They listed Horizon Forbidden West, Fortnite, Destiny 2 and Death Stranding (among others) as streaming options. 4K resolution could prove a competitive advantage against Xbox Cloud Gaming, which maxes out at 1080p resolution and 60fps.

Sony’s upcoming “Project Q” streaming handheld will have an 8-inch, 1080p screen with a 60Hz refresh rate. The accessory is confirmed to use Remote Play (streaming directly from a console rather than the cloud) but could theoretically support cloud streaming as well. The device is set to launch later this year for an as-yet-unknown price.

Game streaming will be exclusive to PS Plus Premium members. The $18 / mo. service already supports cloud gaming for PS4, PS3 and select “classic” titles. It lets you stream available games to PS5, PS4 or PC.
