So this guy Battlescones, I was a bit tipsy the other night and may have poked some fun at the fella but, he did make a legit post that got me messing about.
His post can be found here...

So I've had a mess about this evening and changed a few things in the config.
As is the norm with this sort of thing it's entirely open to debate and may even be placebo but if anyone else wants to give it a bash then please do share your findings.
The directory/path to find the config file is as follows...
C:\Users\Username\Appdata\Local\Packages\Microsoft.SeaofThieves_8wekyb3d8bbwe\LocalState\Athena\Saved\Config\UWP64\
*the Microsoft.SeaofThieves_8wekyb3d8bbw of your directory may have a different string of numbers and letters following the Microsoft.SeaofThieves but you will still find it within C:\Users\Username\Appdata\Local\Packages
When in the correct directory/folder open the GameUserSettings config file with your favourite text editor, it should open with Notepad by default with Windows 10.
Here's what I personally changed...
MaxFPS=141 (three under my desired refresh rate to eliminate tear and vsync use)
SmoothFPS=False (from True)
FullscreenMode=0 (this was set at 2 which is Unreal Engine full borderless, 0 should be true fullscreen but, I'm no expert and may be wrong)
Here's a full list of my config file after changes...
[ScalabilityGroups]
sg.ResolutionQuality=100
sg.ViewDistanceQuality=3
sg.AntiAliasingQuality=3
sg.ShadowQuality=3
sg.PostProcessQuality=3
sg.TextureQuality=3
sg.EffectsQuality=3
[/Script/Athena.AthenaGameUserSettings]
MaxVerticalResolution=0

LastUserConfirmedResolutionSizeY=0
WindowPosX=-1
WindowPosY=-1
bUseDesktopResolutionForFullscreen=False
FullscreenMode=0
LastConfirmedFullscreenMode=2
Version=5

When done, as is the norm, save your config, exit the text editor and then right click on the same config file and select: properties, general tab and tick Read Only and apply it.
