In order to achieve optimal accuracy and lack of impact in the PUBG game, you need to make some settings both in the Windows operating system and in the game itself.

Settings in Windows:
1. First disable the increased accuracy of the mouse pointer to avoid unwanted cursor jumps.
2. Then set the speed of the mouse pointer movement exactly in the center, at the 6th division, in order to have a more stable control of the movement of the sight.

Settings in the PUBG game:
1. Set the sensitivity of aiming through the front sight at 50 to achieve maximum accuracy and control.
2. Similarly, set the sensitivity of the 2X, 3X and 4X sight at 50 to increase accuracy when using optical sights.
3. In order to maintain vertical stability, set the vertical sensitivity multiplier to 1.0.
