Support Our Work
This release marks another massive leap forward for Lenovo Legion Toolkit, representing hundreds of hours of reverse engineering, kernel and hardware investigation, refactoring, and community-driven polishing. Every feature in this update was designed with one principle in min; giving you absolute, uncompromising control over your laptop's hardware, performance, and thermals without the bloat.
Maintaining and advancing a low-level hardware control suite alongside our daily responsibilities requires immense dedication. If Lenovo Legion Toolkit has enhanced your daily workflow, elevated your gaming performance, or solved persistent hardware annoyances for you, please consider supporting our development. Your support directly sustains this project and fuels ongoing research into new Lenovo hardware platforms.
Thank you for being part of our community and making this journey possible!

- AMD Curve Shaper & Overclocking Redesign: Overhauled the AMD Overclocking interface with a unified profile format, master toggle switch, AMD Curve Shaper support, configurable power and current limits, and an option to apply profiles across all power modes.
- Customizable Fn + Q Loop: Introduced the ITS Mode Configuration window, allowing you to customize the Fn + Q loop sequence and disable specific power modes from the cycle, alongside Geek and Creator mode support for older and non-gaming models.
- Redesigned Boot Logo & Startup Customization: Redesigned the Boot Logo utility with a live boot screen preview, animated GIF support (including automatic alpha flattening and proportional scaling), and the ability to toggle the Windows Startup Animation.
- Game Detection & Process Rules Overhaul: Added a Manual Game Detection mode, an Included Processes whitelist, and preserved Windows Game Mode processes across Alt+Tab until the game is closed.
