How to fix screen tearing in Windows 10

Turn on vertical synchronization, enable adaptive synchronization technology, update the graphics card driver, disable enhanced synchronization or quick boot functions to solve the problem of Windows 10 screen tearing.

By turning on VSync in the game or in the graphics card control panel, the frame rate and refresh rate are synchronized; if you use a monitor that supports G-Sync (NVIDIA) or FreeSync (AMD), the corresponding adaptive synchronization technology should be enabled to match the frame rate more intelligently; at the same time, ensuring that the graphics card driver is the latest version, which can be updated through the official website or dedicated software; in addition, turning off optimization functions such as "enhanced synchronization" and "fast boot" in Windows will also help eliminate tear.

how to create a system restore point in Windows

The operation of creating a system restore point is not complicated and should be created manually before performing a critical operation. The reason is that although Windows will automatically create restore points, not every change will be triggered. For example, it should be created manually before installing new software, updating drivers, or adjusting system settings. The method to enable the system restore function is: right-click "This computer" → "Properties" → "System Protection" → configure and enable system protection. It is recommended to allocate 5%~10% of disk space. The manual creation steps are: Go to "System Properties" → "System Protection" → Click "Create" and enter a description, and then wait for completion. It should be noted that the system does not back up personal files, and cannot deal with hard disk corruption or serious poisoning, and cannot recover after deletion. Therefore, it is recommended to use it in combination with external backups.
