## How It Works

This unlocker modifies registry values where the games store their graphics settings, allowing you to set FPS values beyond what's available in the in-game menus. It automatically detects which games you have installed.

## Usage

1. Close the game completely

2. Download and run `hyv-fps-unlocker.exe` from [releases](https://github.com/dromzeh/hyv-fps-unlocker/releases)

3. Select the game and desired FPS value

4. Launch the game

## Fixes For Known Issues

- If the unlocker doesn't detect your game, launch it and change any graphics setting to create the registry entries. The easiest option is changing your resolution, applying it, then changing it back.

- The unlocker can make your graphics settings in-game buggy. You can change any setting (like resolution) in-game to fix it, but your FPS will no longer be unlocked.

- When you modify graphics settings in-game, the game will replace your FPS values, requiring you to rerun the unlocker after each change.

## Building from Source

Requires [Rust](https://rustup.rs/) and [Git](https://git-scm.com/) installed:

```bash

git clone https://github.com/dromzeh/hyv-fps-unlocker

cd hyv-fps-unlocker

cargo build --release

```

The executable will be in `./target/release/hyv-fps-unlocker.exe`.
