Set-CPU-Affinity-for-Rome-2

What is this and why does it exist:
    Total War: Rome 2 is an old game. As such, it has some problems with newer hardware.
    One of those problems is getting stuck at loading screen of a battle. Well, that is the one I encountered. 
    After some research, I've found out these problems have something to do with the number of CPU cores/threads assigned for Rome 2.
    Changing this CPU affinity setting solves the problem in my case. Steps to solve:
        Task Manager -> Details -> Find Rome2.exe and right-click -> Set affinity -> Disable some cores -> DONE!
        I suggest a maximum of 8 cores/threads.
    However, EVERY TIME I launch the game, I have to do this again.
    This is where my simple console app comes into play. It handles the settings for you just with a double click.

Before using:
    It is available for Windows x64 only!
    If you have less than 2 logical cores, it will not work, and simply it will throw an error.

How to use:
    Option 1: Take the .exe file or its shortcut and put it near your Rome 2 shortcut and launch both of them. 
    Order of launch does not really matter. The only difference, if you launch the game first, then launch the app; it takes effect immediately. 
    If you launch the app first, it cannot find the game at initial check (since you did not launch it, yet). 
    Then, the app waits for a minute before checking again.
    
    Option 2: Put the shortcut in `shell:startup`. So, it launches when Windows starts. 
    As long as it is running, you do not have to worry about setting CPU affinity for Rome 2.
    Though, an always open CMD window may annoy you. You do not have to keep it open at all times. 
    As soon as you see the message "CPU affinity is set for Rome2 (PID: -PID for current instance of Rome2-) at -Date and Time-"   
    you can close the window/exit the app, and your settings are set, your current session is ready to play. 
    You just need to launch the app the next time you launch the game, as well.

Where is the .exe:
    You can find it in: /bin/Release/net9.0/win-x64/publish
    It is self-contained, meaning you do not have to download .NET Runtime to make it work. Everything is included. 
    That is why the .exe of such a simple program takes almost 80 MBs.

Enjoy!
