Raw Accel — Rust Rewrite

A rewrite of the Raw Accel mouse acceleration driver's userspace application, built with Rust + Tauri + React.

What is this?

This is a reimplementation of the Raw Accel userspace tool. The kernel-mode driver remains unchanged — this project replaces the C#/WinForms frontend and C++ math layer with:

• Pure Rust backend — all acceleration curve math (classic, jump, natural, power, synchronous, lookup) ported 1:1 from the original C++ headers
• Tauri — lightweight native window shell, replacing the .NET runtime dependency
• React + TypeScript — modern UI (in progress)
• Tiered mode — a new acceleration mode that defines piecewise linear breakpoint curves

Building

Prerequisites

• Rust (stable toolchain)
• Node.js (v18+)
• Raw Accel driver installed (for runtime testing)

Build & Run

cd rawaccel-userspace
npm install
npm run tauri dev

Original Project

The original Raw Accel project is maintained at:
https://github.com/RawAccelOfficial/rawaccel

This rewrite is based on the math and driver interface from that project. The kernel driver code is shared.

Status

• Rust backend — pure Rust math port of all acceleration curves
• Driver communication — DeviceIoControl read/write
• Tiered mode — new piecewise linear acceleration mode
• React UI — curve editor, settings panel, graph visualization
• Full end-to-end testing with driver
