FAQ
Q: How does this mod work?
Fallout Priority elevate the game process priority by calling the WinApi SetPriorityClass.
And higher priority can help the game compete for CPU from other processes.
So your game can run more smoothly and responsively and have fewer lags.

Q: Work on the previous version of F4SE/VR?
There's no F4SE Version Checking in plugin.
And the implementation of this mod is version independent.
So it should work on all F4SE/VR version even SKSE.

Q: Fallout VR Support?
I don't have VR. But it should work as Skyrim Priority SE AE do.

Q: Can you make this mod uses Address Library so you don't have to update?
Address Library is a awesome plugin.
But it's only for version independent game object address searching.
And Fallout Priority doesn't need to interact to game objects.
So this mod don't need it, and is already version independent.

Q: Compatibility?
Compatible with everything.

Q: Does this mod support Linux OS? (Steam Deck)
No, currently this mod is for Windows only.

Q: So how do I know if this mod working?
After game startup. You can open Task Manager by press "Ctrl+Shift+Esc". Go to Details Tab.
Right click on Fallout4.exe/Fallout4VR.exe and check is the value of "Set priority" is High.

If you turned DynamicPriority on in the config. It will be BelowNormal because you are not focus on Game Window.
It will be back to High after you return to Game.

It's Normal by default without Mod or softwares like Process Lasso.

Technical details
Check the Microsoft Official Document for the details:
https://docs.microsoft.com/en-us/windows/win32/api/processthreadsapi/nf-processthreadsapi-setpriorityclass#parameters

# Idle          = 0
# Below Normal  = 1
# Normal        = 2
# Above Normal  = 3
# High          = 4
# Realtime      = 5     (Require run F4SE as Administrator)

Fallout Priority uses High by default
It's a safe priority that won't interrupt critical jobs by Windows.
You can change it in PriorityMod.toml If you want other priority.

Note
About Realtime Priority
https://docs.microsoft.com/en-us/windows/win32/procthread/scheduling-priorities#priority-class
You should almost never use Realtime, because this interrupts system threads that manage mouse input, keyboard input, and background disk flushing. This class can be appropriate for applications that "talk" directly to hardware or that perform brief tasks that should have limited interruptions.

For SkyrimSE/Enderal SE
This mod can also work on Skyrim SE/Enderal SE directly.
The only thing you need to do is change the install path:
"Data/F4SE/Plugins" to "Data/SKSE/Plugins"

Or simply download Skyrim Priority SE
