## Overview

This repository distributes a Windows D3D12 proxy that enables DLSS Frame Generation on RTX 20/30 GPUs. The documented workflow is: install the proxy and INI beside a game, let the game’s existing Streamline/DLSS-G calls reach the embedded NVIDIA runtime, and configure the generation limit and kernel optimization. It also documents compatibility routing, diagnostics, and capture/replay. The tree contains no runtime source or binaries, so runtime links reflect README-described behavior; capture/replay is documented but its named guide is absent from the tree.

Main entry points: [`dlssg_sm86.ini`](https://github.com/sdli1995/dlssg_for_sm86/blob/main/dlssg_sm86.ini) (Runtime INI), [`alternatives`](https://github.com/sdli1995/dlssg_for_sm86/tree/main/alternatives) (Alternate Proxies), [`docs/INSTALL.md`](https://github.com/sdli1995/dlssg_for_sm86/blob/main/docs/INSTALL.md) (Installation Guidance), [`docs`](https://github.com/sdli1995/dlssg_for_sm86/tree/main/docs) (Capture and Replay)
