PS4 developers must integrate Vita remote play into all of their games, according to a report.
A PS4 developer source “with a proven track record for accuracy” has told Eurogamerthat only games that require the use of the PS4 Eye will be exempt from Vita compatibility.
The report said remote play will downscale the 1080p resolution of PS4 games to the Vita’s own native 960x544 display, which is then streamed over WiFi to the Vita.
Although the Vita can be used with the PS3 in a similar way, acting as a controller and second TV at 480p, but many developers have yet to pick up the feature.
