Configure Window Size and Display Settings

Locate the Configuration File

Find config/lwjgl3ify.cfg in your game directory. This file controls how the mod behaves, including your window dimensions and display options.

Edit Window Resolution

Open the config file in a text editor. Look for window width and height settings. Modify these values to your preferred resolution—for example, changing from 1024×768 to 1920×1080. Save the file.

Apply Raw Mouse Input Settings

Within the same config file, locate the raw mouse input option. This setting improves mouse responsiveness by reading input directly from your device, bypassing operating system acceleration. Enable or disable this based on your preference—some players find it essential for precise control, while others prefer standard input handling.

Restart the Game

Close Minecraft completely and relaunch it. The mod reads configuration values at startup, so changes won't take effect until you restart. Your new window size and mouse settings should now be active.
