CPU Core Parking - Fix for "CPU causing rF2 stuttering"

Read about CPU Core parking on the rF2 Discord support this morning.
I had no idea about CPU Core parking or what it meant until today.
Someone had stuttering issues with more AI being added and the stuttering was linked to CPU spikes on their PC. The solution was to stop the CPU Cores being parked.
Parking a CPU Core is a power setting that the OS uses. It is effectively saving energy by disabling CPU cores. You can see CPU performance in the task manager.
Some clever chap has written a manager program to check your CPU Core usage:

Yes, finding the tiny text download link is a pain.
The page explains how it works, but it's pretty simple, so I'll explain here.
There are 2 sliders on the tool.
The Core Parking Index:
Controls how many cores are allowed to be "parked" or disabled by the OS.
On my laptop I have 4 cores.
If I want all 4 to be enabled all the time I set this to 100%.
If I want only 3 to be enabled all the time I set this to 75%
50% for 2 cores
25% for 1
and 0% allows the OS to disable all the cores if it wants
The Frequency Scaling Index:
This allows you to control the speed of your CPU.
The OS would normally step your CPU speed down when it's not in use to save energy.
If you set this to 50% your Cores will always run at 50% speed.
On my laptop this is 5%. I've tested 100% and clicked apply and they all maxed out speed.
It's a simple tool to use and may be useful for some of us that are having CPU performance issues in rF2.
