The problem with FPSOs in multiplayer (Red Dead Redemption 2)

Hi all.
Actually I have some kind of game with FPSOs in multiplayer.
Sobsno I iron powerful: RTX 2080Ti, 32gb ram, i9-9900, etc.
The problem is in the network. Monique I have a 144 Hz 2K. In campaign mode the FPS is normal, no breaks no. But networking is a nightmare. I even put all on a minimum resolution of 640x480 - the game seems to 60-80 FPS. On the ultra all the same.
