Fix freezing & crashing on modern multicore CPU PCs

1. We create our FIRST .bat file with the following code (this bat can be stored on your desktop or anywhere really):
What this code does is finding the SaintsRowTheThird_DX11.exe active process and setting the 0,1,2,3 cores as the only active. Disabling the rest. Basically the same task that you would do manually but using Windows PowerShell.

2. Ok, our first .bat file is kinda awesome but in order for this to work, the game has to be launched first. Here comes the second .bat file. This is the one we'll be using to actually launch the game when we're done. So create the second .bat and paste the following code:
What this code does is:
1. It launches the steam App number 55230 (Saints Row the Third that is).
2. Starts the countdown of 20 seconds (adjustable). We give your PC time to launch the game.
3. When 20 seconds are over, it starts our first .bat file which finds the process for us and adjusts the cores affinity.

This way we automate almost everything. From now on, you only have to click on your second .bat in order to start the game properly with correct CPU core settings.
This guide might seem a little bit too complicated, but remember, there is also an annoying pre-game launcher that asks the DirectX version you wanna be using. That's also why we are giving a 20 second countdown, so you have time to select DirectX 10-11 version and start the actual executable. (Yes, this guide is for 10-11 DirectX version, but I guess you can adjust it for 9 as well if needed).

Also, this guide would be perfectly viable for other older games that have the same bad taste of becoming unstable on modern Multicore CPUs, so be sure to remember about it.
