Nvidia G-Sync Does Not Work With BF6

Old thread but let answer for those who also have problems. Try limiting your frame rate. The are two options that worked for me:

In NVIDIA settings: Enable G-Sync, disbale V-Sync.

In Battlefield 6 - Fullscreen mode (better because Windows doesn't run on 144Hz all day):

1. Set refresh rate in Windows to 60Hz. 
2. In Battlefield disable V-Sync, set fullscreen mode and set your refresh rate to your desired rate (for me it is 143,86Hz).
3. Limit the framte rate in BF6 settings: Graphics -> Graphics -> Advanced -> Frame Rate Limter (for me 139FPS 60FPS in menu)

In Battlefield 6 -Borderless mode (my option, more convenient):

1. Set refresh rate in Windows to your desired rate (for me it is 143,86Hz).
2. In Battlefield disable V-Sync and optionally limit the framte rate in BF6 settings: Graphics -> Graphics -> Advanced -> Frame Rate Limter. I didn't and it works well.
