## What it is
A pseudo-driver library that translates Direct3D 8 API calls and bytecode shaders into their Direct3D 9 equivalents to improve compatibility and stability of old games. It also enables D3D9-based modding tools like ReShade to work with D3D8 games.

## Use cases
- run old Direct3D 8 games on modern Windows
- fix rendering issues in legacy D3D8 games
- use ReShade with Direct3D 8 games
- translate D3D8 shaders to D3D9
- improve stability of games using Direct3D 8 rendering

## When to choose
- you want to play or mod a Direct3D 8 game with D3D9 tooling like ReShade
- you need a drop-in D3D8 compatibility layer without extra configuration

## When to avoid
- you need configurable behavior like forcing VSync off — use dxwrapper instead
- your game targets Direct3D 9 or later natively

## Facets
- artifact type: library
- maturity: active
- function: graphics, middleware
- domain: gaming-tools, graphics, windows
- platform: windows, cpp
- tags: d3d8, d3d9, directx, api-translation, pseudo-driver, reshade, game-compatibility
