Question Why do i get 20-30 fps in game but not in lobby? (Warzone)

[Zavier559]

Whenever I play warzone and im in the lobby, i get around 100-300 fps but when im in game its at 20-30 fps and its rlly not good and really hard to play.
This has happened all of a sudden and didnt use to have this problem. How can i fix? Im also running on a laptop.

Windows Update "fixed your drivers" ?
144hz means you turned on Fast Sync in nVidia drivers, right ?
V-sync in game should be off too, unless they have a Fast Sync or Adaptive option.
