NVIDIA DLSS Super Resolution SDK 3.1 Out Now, Adds Option for Apps to Update DLL Files

Without much fanfare, the official GitHub repository for the NVIDIA DLSS Super Resolution SDK was updated to version 3.1. Here’s the changelog:

• Added ability to stay up-to-date with the latest DLSS improvements
• Added ability to customize DLSS based on different scaling ratios and game content.
• Updated DLSS Programming Guide for new API additions
• Performance and Optimization fixes
• Bug Fixes & Stability Improvements

Indeed, the first point in that bulletin list points to the newly added ability for applications to enable over-the-air (OTA) updates to newer DLSS .dll files. While there have been workarounds (such as Brad Moore’s DLSS Swapper Tool), this is obviously going to be a superior option, provided that game developers opt into that.

Interestingly, the updated NVIDIA DLSS Super Resolution SDK programming guide mentions that it’ll be possible for developers to choose between various presets.

While default settings will still result in top-of-the-line quality, those in search of peak image quality for their application can take advantage of varying DLSS presets. Presets tweak different aspects of DLSS in order to cater to different scaling ratios, game content, etc. DLSS Super Resolution presets are subject to change with each revision, but the following serves as a general guide for experimentations with the current presets:
• Preset A (intended for Perf/Balanced/Quality modes):
o An older variant best suited to combat ghosting for elements with missing inputs (such as motion vectors)
• Preset B (intended for Ultra Perf mode):
o Similar to Preset A but for Ultra Performance mode
• Preset C (intended for Perf/Balanced/Quality modes):
o Preset which generally favors current frame information. Generally well-suited for fast paced game content
• Preset D (intended for Perf/Balanced/Quality modes):
o The default preset for Perf/Balanced/Quality mode. Generally favors image stability
• Preset E (Unused)
• Preset F (intended for Ultra Perf/DLAA modes):
o The default preset for Ultra Perf and DLAA modes.

The more adventurous among you can already download the new NVIDIA DLSS Super Resolution 3.1.1 .dll file via TechPowerUp and try to apply it to existing games. Beware that results may vary.
