hyv-fps-unlocker

A Windows registry modifier that unlocks FPS limits for Honkai Impact 3rd and Honkai: Star Rail.

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
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.
