To achieve the best accuracy and smoothness of mouse movement in the PUBG game, certain changes should be made to the settings of both the Windows operating system itself and the game.

In the beginning, it is recommended to disable the increased accuracy of the mouse pointer in the Windows settings. This can be done by going to the «Control Panel», selecting «Devices and pointers», and then uncheck the option «Increased mouse pointer accuracy».
Further, to obtain the optimal speed of the pointer in the center of the screen, it is recommended to set the value to 6 division. To do this, go to the «Control Panel», select «Mouse Options» and move the pointer speed slider by 6 division.

Now let's move on to the settings in the PUBG game. In the graphics settings of the game, it is recommended to limit FPS (the number of frames per second) to 60. To do this, open the graphics settings in the game and find the FPS limit setting. Set the value to 60 to ensure stable performance and smooth gameplay display.

It is also recommended to set the overall sensitivity at 50 in the game control settings. This will allow you to control the character in the game more accurately and easily, especially when shooting or performing quick movements.
Finally, it is recommended to set the vertical sensitivity multiplier to 0.7. This will help balance the horizontal and vertical mouse movements, making them more consistent and preventing possible inversion of the view in the game.
