Nvidia DLSS 3.1.13 SDK adds DLAA Performance Quality mode and mysterious Preset G

Nvidia just released the DLSS 3.1.13 SDK for game developers and, besides the usual bug fixes and stability improvements, this latest version adds the Deep Learning Anti-Aliasing feature as a Performance Quality mode for DLSS plus it introduces a new preset.

What is now known as Preset G was first teased in a recent Unreal Engine 5 stream that showcased the latest AI advancements implemented in the popular game engine. The purpose of this new preset is still unknown, as the release notes only mention that it will remain unused for now, just like Preset E that has been included with the first version of DLSS 3. Nvidia may use one of these in conjunction with the real-time neural radiance caching technique.

Previously, DLAA was invoked by completely ignoring the DLSS resolutions and rendering at native resolution. However, with the new DLSS SDK version, game devs can implement a DLAA Performance Quality mode along with the existing DLSS Quality / Balanced / Performance / UltraPerformance modes. Unfortunately, it looks like there is no UI choice implementation yet, so devs may still find it easier to just add it as a separate option outside of any DLSS modes.

Users who want to test if any image quality improvements have been included with the 3.1.13 version can do so via the DLSS Tweaks app that forces games to use the latest implementation.
