## Overview

The README presents DLSS 5 Manager as a Windows mod manager and one-click installer for DLSS 5, ReShade, OptiScaler, and Live Flow, with locally stored metadata, layouts, and configuration backups. The available tree and source excerpts are limited to ScreenNative, especially a frame-feeding host for 32-bit games; they do not expose the manager UI, installer, or storage implementation. The graph therefore distinguishes documented product capabilities from the evidenced native rendering path and omits uncertain wiring.

Main entry points: [`ScreenNative/screen_worker.cpp`](https://github.com/nodix-tech/dlss-5-manager/blob/main/ScreenNative/screen_worker.cpp) (64-bit screen host), [`ScreenNative/src/feed_ipc.h`](https://github.com/nodix-tech/dlss-5-manager/blob/main/ScreenNative/src/feed_ipc.h) (32-bit game add-on), [`ScreenNative/flow_shader.h`](https://github.com/nodix-tech/dlss-5-manager/blob/main/ScreenNative/flow_shader.h) (Motion and HUD analysis), [`ScreenNative/dll_trust.h`](https://github.com/nodix-tech/dlss-5-manager/blob/main/ScreenNative/dll_trust.h) (Runtime trust gate)
