Game Helper is primarily used as a keymapping tool for mobile games like Free Fire and PUBG Mobile when running on the Phoenix OS Android-based desktop environment.

In the Phoenix OS community, "repack" versions of Game Helper are often modified by third-party developers (like Tech Drock) to fix bugs found in the official Phoenix OS installer, such as joystick delays or LT/RT trigger failures on controllers.

To help you get the best setup, could you tell me which you are running (e.g., DarkMatter, ROC, or official) and which specific game you are trying to optimize? I can then provide a custom keymap configuration or specific performance settings for that title.
