## What it is
RT64 is a modern N64 graphics renderer built on D3D12, Vulkan, and Metal, designed for enhanced gameplay in emulators and native game ports. It offers high-accuracy rendering with features like widescreen support, high frame rate interpolation, texture packs, and planned path tracing capabilities.

## Use cases
- render N64 games with modern graphics APIs in a native port
- play N64 games in widescreen or ultrawide
- interpolate N64 game visuals to 60 FPS or higher
- apply HD texture packs to N64 games
- reduce input latency when emulating N64 games
- uprender N64 games at higher resolution with downsampling
- add a high-accuracy N64 renderer to a game port

## When to choose
- you are building a native port of an N64 game and need a modern renderer
- you want enhanced N64 visuals like widescreen, HFR interpolation, or HD textures
- you need accurate N64 RDP rendering without game-specific hacks
- you want stutter-free rendering via ubershaders

## When to avoid
- you need emulator plugin support or ray tracing today, as these are not yet in this repository
- you need a general-purpose emulator rather than a renderer library
- you target platforms other than Windows, Linux, or macOS
