Developer reveals the DLSS version in the Nintendo Switch 2

When the Nintendo Switch 2 was unveiled, it was revealed that the new console utilizes a form of upscaling technology, which was later confirmed to be NVIDIA's Deep Learning Super Sampling (DLSS) tech. However, neither Nintendo nor NVIDIA confirmed which version of the software was present in the Switch 2.

That has seemingly just changed as a developer known for specializing in porting games over to the Nintendo Switch 2 has posted on BlueSky claiming the Switch 2 uses DLSS 3.1. That developer is LynxByte Games, which shared an image containing all of the "unique features" within Nintendo's latest console.

The full list includes DLSS 3.1, ray tracing, 4K HDR (TV), 120Hz handheld, GameChat (voice/video), new Joy-Cons w/ mouse mode, improved sticks, Pro Controller w/ extra buttons + jack, Full backward compatibility, Bluetooth 5.1, Wi-Fi 6, HDMI 2.1, LAN, USB-C cam, and MicroSD card. The only feature listed there that wasn't already publicly announced was the DLSS version. Notably, this news hasn't been confirmed by NVIDIA or Nintendo, so you should definitely take it with a grain of salt.

However, we can make an educated guess on the validity of these claims based on the hardware we know is in the Nintendo Switch 2. The new console utilizes a custom NVIDIA Tegra T239 SoC, an Ampere-based GPU, but with Ada Lovelace's Optical Flow Accelerator. Ampere-based GPUs supported DLSS versions up to DLSS 3.0, with Ada Lovelace kicking off DLSS 3.0 until DLSS 4, which was introduced with the Blackwell generation of graphics cards.

Since the Switch 2 uses an Ampere-Ada Lovelace combination architecture, it can technically support the purported DLSS 3.1 version, along with older versions of DLSS. While it still hasn't been confirmed by NVIDIA or Nintendo, the DLSS 3.1 claim does seem accurate. At least based on the hardware available within the Nintendo Switch 2.
