DLSS 3.5 SDK now available
NVIDIA has released a Software Development Kit (SDK) for its latest iteration of Deep Learning Super Sampling (DLSS) technology.
This week has certainly been a whirlwind in the world of gaming technology. NVIDIA has made waves by unveiling their revamped DLSS3 library, placing a significant emphasis on enhancing ray tracing capabilities. Meanwhile, AMD has finally lifted the veil on their long-anticipated DLSS3 competitor, FSR3. As both upscaling technologies are slated for ‘fall’ release, some expect the first titles to drop already next month.
Tech reviewers will be looking at the FSR3 and DLSS3.5 releases closely. They hope to compare them side by side and one such titles that can allow this is Cyberpunk 2077, which is now officially set to receive DLSS 3.5 and FSR3 patches at some point.
AMD has disclosed that there are presently a dozen games on the upcoming FSR3 compatibility list, with more in the pipeline. NVIDIA, on the other hand, has only confirmed DLSS3.5 for titles such as Cyberpunk, Portal RTX, and Alan Wake 2, with promises of more additions in the near future. All these technological advancements are slated for release in the coming fall.

In a parallel development, NVIDIA has unveiled a new software development kit (SDK) that conveniently includes support for DLSS 3.5. This was spotted by “emoose,” creator of DLSSTweaks, a tool that allows gamers to tinker with DLSS settings and profiles.
It’s crucial to note that DLSS 3.5 doesn’t automatically enable ‘Ray Reconstruction.’ This feature necessitates integration into a game’s graphics pipeline by the developer. For those using Unreal Engine 5, the process is expected to be easier, as NVIDIA offers a 3.5 UE5 plugin and Redditors have already found a readme file that explains how the plugin is structured.
DLSS 3.5 UE5 plugin components
- DLSS Super Resolution (DLSS-SR)
- Deep Learning Anti-Aliasing (DLAA)
- ***Coming Soon!*** – DLSS Ray Reconstruction (DLSS-RR)
However, as DLSS 3.5 comes with improved upscaling algorithms, some gamers have already swapped out libraries and reported notable improvements in image quality, along with a reduction in ghosting in games such as Last of Us or Need for Speed Unbound. Nevertheless, it’s essential to bear in mind that merely swapping the DLL won’t activate ray reconstruction. Developers must take deliberate steps to incorporate this feature into their games.
