Configuring the Cursor Movement Scaling JVM Argument

Depending on your monitor setup, display resolution, and system settings, the default movement distance applied to center your cursor might stop short or overshoot the middle. You can calibrate this using a dedicated Java Virtual Machine (JVM) argument.

Adding the Scaling Argument

To apply a custom scaling factor, modify your Minecraft installation profile in your launcher:

1. Close Minecraft if it is currently running.

2. Open your launcher and navigate to your game installations or profiles list.

3. Select your modded profile and locate the JVM Arguments or Java Arguments text field.

4. Scroll to the end of the existing argument string, add a space, and append:

-DcursorMoveScalingValue=<value>

5. Replace <value> with your chosen scaling figure to tune the travel distance.

6. Save the profile changes.

Testing the Cursor Placement

After saving your argument:

1. Launch the game and enter a world.

2. Open a chest, inventory screen, or crafting table.

3. Check whether the pointer lands directly on the center crosshair position.

4. If the cursor travels too far or not far enough to reach the middle, close the game, raise or lower the value in your launcher arguments, and test again until centered.
