That said, there was so much chatter out there before the reveal that there's still plenty of room for speculation, particularly when it comes to the patents that appeared in the run-up to Nintendo's trailer drop.Here to provide the technical rundown of it all are the experts over at Digital Foundry. The tech wizards recently dug into a patent suggesting that Switch 2 will utilise 4K AI upscaling technology, explaining what it could mean for the console and how Nintendo might put it into practice.Now, Digital Foundry actually shared the following video two weeks ago, before the Switch 2's 16th Jan reveal, but since Nintendo's trailer was far from a rundown of the upcoming console's specs, it's still definitely of interest as we look for more details.According to DF's Alex Battaglia, the patent in question was filed by Nintendo's European research and development team at the end of last year and outlines a similar AI upscaling process to Nvidia's DLSS technology transforming a game's lower internal resolution to a higher, 'upped' resolution. The resolution numbers referred to throughout are about transferring 540p to 1080p, though the patent specifies that this is only an example and the technology could also be applied to higher resolutions like 1080p to 4K something Switch 2 could utilise in its dock, for example. A rundown of Nvidia's AI upscaling techSo far, so DLSS. But Digital Foundry explains that the Nintendo patent promises more than Nvidia's alternative, with references to upscaling via the cloud, single-image upscaling and more. A key difference, Battaglia flags, is how the patent suggests it would be able to switch out DLSS upscaling models in real-time, so even more strenuous sequences (where the usual upscaling learning wouldn't be able to keep up) can benefit from a boost while keeping up the frame rate.Much like the point that was made by accessibility/cultural consultant Laura Kate Dale back when we first spotted the patent, Battaglia also notes that the technology could be used to reduce game sizes and fit them onto Nintendo's comparatively smaller carts.In short, the patent is broad (hardly a first from Nintendo patents), but its overall message is that machine-learning upscaling could occur either via cloud streaming or from the device itself, which is a rather exciting prospect.Battaglia seemed confident after his initial analysis that this upscaling tech will be utilised in Switch 2, but, as is always the case with patents, there's never any guarantee that we'll see the contents come to fruition. Nintendo is prone to staking its claim early, and this DLSS-esque tech may simply be something it is working on in the background.Who knows? However, for those with an interest in all things tech, the following is still well worth a watch:Subscribe to Nintendo Life on YouTube794kAnd the patent speculation doesn't end there. Just last week, ComicBook.com flagged a 2022 Nintendo patent, which recently resurfaced following its European application. This one was all about motion sensor technology, particularly how a sensor placed on top of a TV can register and interact with a handheld device.It has a faint whiff of something Wii-related (or maybe something more in line with the Xbox Kinect), and the outlet speculated that such tech could be utilised in Switch 2 for more motion-controlled gaming a Wii library, perhaps.Much like the aforementioned upscaling note, just because a patent exists, it doesn't mean Nintendo is necessarily planning to use its contents on Switch 2. Sure, it would be fun for a little bit of Wii nostalgia, but who's really going to want to plonk another sensor on top of their TV? Not us.Back to waiting for more Switch 2 news so we can know the console's features for sure, we guess. Come on, Nintendo! DLSS has been mentioned in past reportsDo you think we'll see either of the above patents in action for Switch 2?
