The default V-Sync setting has been changed to Off to provide a more consistent gameplay experience, especially in Extra Level 20.
If you are using an NVIDIA graphics card, please make sure NVIDIA Control Panel → Manage 3D Settings → Vertical Sync is set to Use the 3D Application Setting or Off.
Due to technical limitations, we are currently unable to completely eliminate gameplay differences caused by different V-Sync settings. To ensure the intended gameplay experience, please use the recommended settings above.
We apologize for the inconvenience and appreciate your understanding.
