The new Switch iteration will support Nvidia's Deep Learning Super Sampling, or DLSS, a novel rendering technology that uses artificial intelligence to deliver higher-fidelity graphics more efficiently. That will allow the console, which is also set for an OLED display upgrade, to reproduce game visuals at 4K quality when plugged into a TV, said the people, who asked not to be identified because the plan is not public.
I'm not sure I can believe that the Switch will be able to output 4K-graphics. Sure, DLSS technically is not real 4K, but still. The console would have to be way more powerful and, thus, probably way more expensive for this even to make sense.
If the next Switch doesn't end up reaching 4K, I'd still in for an upgrade if it has smaller bezels and maybe a more consistent 720p in handheld, respectively 1080p docked. I feel many games would be perfect on this little device, but they can't run properly as the downgrades that have to be made are too much. Think Apex Legends.
I love the Switch.
