Got such a problem and found this topic https://www.seaofthieves.com/forum/topic/31551/fps-locked trying to find the solution. So the solution is still not found.
Whatever your system is - SoT caps your FPS at 72 (half of monitor hz) if you use 1440p resolution (probably not just 1440p for some) at full screen.
Going to windowed mode or switching to other resolutions (1200p, 1080p, etc.) - breaks this cap again letting FPS fly.
I tried switching there and back windowed-fullscreen modes, playing with resolutions and at one time somehow I got in options - 2 types of my native resolutions. One of them worked with 1440p and no FPS cap...but on the next day it was all the same. Problem stands.
Vsync off/on, configuring special options in Nvidia panel for SoT doesn't help too.
So anyone found the solution for this problem maybe?
