Digital Foundry put the Remote Play feature of the Vita and PS4 through some testing. According to them, Vita's Remote Play doesn't really provide the same great experience Wii U owner's get from the Off TV Play feature using the GamePad. The full article about the Vita Remote Play testing and results can be read at Digital Foundry
. Here are some quotes from the feature article that talk about the comparison between Vita's Remote Play and Wii U's Off TV play.
"There's a really high expectation level with Vita Remote Play because the core technology has been proven to work on not one, but two different systems – the excellent Wii U GamePad and Nvidia's Shield handheld."
"Image quality generally looks pretty decent [on Vita], but despite the resolution advantage, it's far from the high quality presentation we get from the Wii U – closer to the picture you tend to get from Nvidia Shield, but still notquite up to scratch."
"We can also confirm that Vita Remote Play does indeed run at 30fps – a commonality it shares with the current version of the Nvidia Shield software (though this is set to be addressed in next month's update, which should offer 720p60 – and even 1080p60 if you tether via USB), but a world away from the beautiful, full 60Hz refresh of the Nintendo GamePad."
"In truth, while image quality and frame-rate matter, the more readily apparent issue is the size of Vita's screen – lining up shots in Killzone and Battlefield 4 proved extremely difficult because the targets were so small. It's surprising just how much of a difference that extra inch on the GamePad's display makes."
"It was perhaps a bit much to hope that Vita Remote Play could match up to the Wii U GamePad, or even Nvidia Shield's performance. Nintendo built its system around its controller – ultra low latency was built into the design, while Vita Remote Play simply doesn't have that priority for Sony."
"However, whether we're talking about image quality, latency, frame-rate – or the simple fact that 1080p gaming doesn't always translate well to a five-inch screen – we couldn't help but feel that we were getting a less than ideal experience, and that nothing compares to just picking up the Dual Shock 4 and playing PS4 games in the conventional way."
"As it stands, PS4′s Vita Remote Play functionality is a really cool value-added extra, but while fun, it can't really be compared with the Wii U GamePad experience."
