What causes high latency in single player games?

Currently playing dawnwalker on my laptop rtx4090 16gb.
I am getting 60-70 fps on “ quiet mode “ ultra settings but LAT is 80-100.
Is this normal?

V sync is off in game settings.
How can I lower the latency?

Its a single player game so not sure whate causing the high latency. Should I play with wifi turned off?
