NVIDIA Releases DLSS Super Resolution SDK Update, Shows 42% GPU Time Improvement in CP 2077 Overdrive with SER

wccftech.com:

A few hours ago, NVIDIA released a new DLSS Super Resolution SDK (version 3.1.10) on GitHub. According to the changelog, DLSS Super Resolution 3.1.10 comes with performance, optimization, and stability improvements, not to mention unspecified bug fixes.

Since the release of DLSS Super Resolution SDK 3.1, game developers could opt-in to automatically update the .dll file of their games. Previously, users were forced to do that manually, although a modder released a tool called DLSS Swapper to make that process easier.

As promised last week, NVIDIA also updated its Streamline SDK to version 2.0 and shared publically the Frame Generation plugin. This could open up to user-made integration by modders; we may have news on that front soon, so stay tuned.

With the Game Developers Conference 2023 now officially underway, NVIDIA also began sharing informative videos on its YouTube channel dedicated to fellow game developers. For example, there's a video that shows how the analysis of Cyberpunk 2077's upcoming RT Overdrive mode update with the Nsight Graphics software led CD Projekt RED to optimize the path tracing with Shader Execution Reordering (SER).

Here's an NSight Graphics profile of Cyberpunk 2077 captured on an Nvidia RTX 4090 graphics card. The GPU Trace lets you analyze throughput per frame, giving you a bird's eye view of GPU time for performance markers involved in rendering the game.

This Trace uses the Ada RT metric set. Notice here that the path tracing DispatchRays call is running slowly. We can click on Trace analysis to take a deeper look.

Here we see that lighting is consuming a lot of the frame's render time and, examining further, that DispatchRays is the most significant culprit as we suspected. DispatchRays
