We played through sections of BioShock Infinite and Tomb Raider and came away impressed more by the experience rather than the technological nuts and bolts. The ability to decouple PC gameplay from the office/den and play wherever you want in the home generally works well very well indeed, and provided you have powerful Wi-Fi, there should be much more range here than with Wii U GamePad off-TV play. The Shield itself supports dual-band 802.11n, so it's good to know that Nvidia hasn't skimped on the handheld's Wi-Fi capabilities.
The streaming element of the Shield package is flagged as a "beta" and hopefully Nvidia will continue to work on it. Clearly there are areas for improvement - we'd like to see target frame-rate and bandwidth selectables, so we can tailor the experience to match the quality of our Wi-Fi, and a stronger focus on video consistency would help a great deal too. We'd also like to see more titles supported too, something Nvidia promises is coming once the tech moves out of beta.
What we have for now though is an extremely promising beginning. PC gaming is indeed 'portable' in the way that Nvidia envisaged, and it's now clear to see why Valve's Gabe Newell believes that latency isn't an issue for the low-end streaming Steam Boxes that are (apparently) in development, because response here is a match for current-gen console in our testing. While latency on OnLive was clearly an issue, relocating the "gameplay over IP" concept into the home clearly works well, and after the Shield experience we can't wait to test out the PlayStation 4 rendition of the same core technology.
"There's a clear hit to image quality in the PC streaming mode, but the small, high pixel density display works well in making the macroblock artefacts hard to pick up on for the most part."
We simultaneously captured both the PC and the Shield running the same gameplay and put together this image quality comparison. We've slowed down playback so YouTube's constrained bandwidth allowance has enough bits to go around in order to retain as much picture quality as possible. You can also see how Shield interfaces very easily with your PC in the intro segment. Make sure you watch this at full 720p resolution.
Nvidia Shield: the Digital Foundry verdict
It's difficult not to be impressed with the entirety of the Shield experience. We love the zero-compromise approach to the controller design, and the fact that Nvidia has unashamedly targeted the core gamer for its debut games machine. Shield is undoubtedly a niche product and clearly won't be the best buy for everyone, but at the same time we couldn't help feel that this was a handheld built for
us.
The ability to stream PC gameplay over an internal Wi-Fi network is another clear bonus, proving surprisingly robust across a range of networking scenarios. While frame-rates, refresh consistency and image quality could be improved, the quality of response from the controls is very good - highly playable and on par with current-gen console. This element of Shield is still in beta, but even in its current state, it's well worth checking out
