So PSNow is still stuck streaming at 720p, and like 4 frames of latency
However, the specs don't alter when streaming PlayStation 4 games, meaning that the standard 1080p framebuffer gets a 720p downscale before encoding, then it's blown up to the display output set on the client. The result for PS4 titles is undoubtedly softer owing to the resolution downscale, but image quality is affected in other ways too - Killzone Shadowfall's soft volumetric lights cause clear issues for the encoder, causing some obvious macroblocking. Super Stardust Ultra's combination of constant fast motion and fine detail is even more of an issue - resulting in some ugly artefacting. It's still playable - but it just looks poor. The issue is exacerbated if you have the base PS4 connected to a 4K screen: an original 1080p image is downscaled, encoded, decoded, then upscaled to 1080p before the display itself upscales again to 4K. It's not pretty, but by and large, you accept a certain loss of fidelity with cloud systems.
Latency | Killzone Shadowfall (30fps lock) | Killzone Shadowfall (unlocked) | Ultra Street Fighter 4 | Super Stardust Ultra | Heavy Rain |
---|---|---|---|---|---|
Local | 110ms | 108ms | 58ms | 38ms | 110ms |
Ethernet | 174ms | 170ms | 126ms | 118ms | 172ms |
WiFi | 185ms | 180ms | 128ms | 120ms | 188ms |
So it's not the worst thing ever
The concept of fully playable access to your games wherever you are clearly has some value - and there is some evidence that Sony is planning for something along these lines. For example, it is indeed possible to port over save game progress from PlayStation Now to your local console - we were able to play Killzone Shadowfall via the cloud, then transfer our save to cloud storage and retrieve it locally on a standard PS4. It's a bit of a faff for now, but the foundations are there for Now to integrate with standard, local gaming.
Clearly, Sony has invested substantially into PlayStation Now and despite the sometimes wobbly image quality and extra lag, there's something here that works. Consistency in response - even if it's four frames behind local systems - seems to work in maintaining playability. Improved image quality for PS4 titles is a must, but even here, the system is still serviceable enough on most titles. But fundamentally, Sony has a history of experimenting with cutting-edge technologies then falling short in delivering quality content - PS Vita, PlayStation Move and even PSVR lack the support of Sony's top development teams. There's potential in Now, but it needs a genuinely exciting vision to make it truly deliver - a 'greatest hits' catalogue of old games at £13 per month isn't going to cut it.
