Windows 10: I want to set CPU affinity per RegEdit

I've searched the entirety of the internet for an answer and it fucking blows my mind how EVERY response I could find totally avoids the actual question the user asked.

Listen, I do not want to set CPU Priority, I can not use a third-party tool, I can not run a batch file or shortcut, I can not set it per TaskManager and I do not want you to ask "y u want do this". I swear those were ALL the responses I found on this issue.

I found out you can set CPU Priority with "CPUPriorityClass" as Dword:0x00000003 to set it to high. Okay, got that.

Now I want to set the CPU Affinity to use 2 cores less than 8 per RegEdit.

That's all I want. That and nothing else.

(Btw it was an absolute PAIN in the ass to select a flair here. It kept popping up off screen.)

CPU / CPU Processor problems / Processor affinity

We appreciate the information you provided. Your processor is working as expected. CPU affinity is only showing CPU (0) since 1 processor is working at the moment. It's very likely that your computer is using a balanced power plan, so we suggest changing
your power plan to High Performance by following these steps:

• Right-click Start.
• Click Power Options.
• Choose High Performance.

In addition to that, we recommend installing the latest updates to keep your system current and secure. Go to
Start > Settings > Update & Security > Check for updates.

Some programs may also be automatically launching whenever you boot your computer, affecting the performance. To disable them, follow these steps:

• Right-click your taskbar.
• Click Task Manager.
• Under the Startup tab, find the programs that you don't need.
• Right-click the program and choose Disable.

You're also using your computer for a game that was designed to run on an earlier version of Windows, so it's possible that it's slowing down your computer. In this case, use the Compatibility Troubleshooter to find and fix problems with the program using
these steps:

• Click Start.
• Type Troubleshooting and press Enter.
• Click Run programs made for previous versions of Windows.
• Click Next.
• Choose the program from the list and click Next.

How to set 8 core cpu in affinity settings

Here is how to set your affinity settings using 8 core cpu splitting them into two 4 cpu cores

cmd.exe /c start "WoWSLauncher" /affinity F "C:\Games\World_of_Warships\WoWSLauncher.exe"

As you can see I added "F" next to /affinity that will let you use just 4 cores 0,1,2,3

I can do it easy in task manager but got to keep doing it everytime i want to play the game.

So if you want to use 0 1 2 3 cores just for the game you would add "F" in your line like so..

for cores 4,5,6,7 Do this....

Add F0 next to /affinity like so

cmd.exe /c start "obs32" /affinity F0 "C:\Program Files (x86)\obs-studio\bin\32bit\obs32.exe"

cmd.exe /c start "obs64" /affinity F0 "C:\Program Files (x86)\obs-studio\bin\64bit\obs64.exe"

Depends on if using 32 or 64bit of the os.

If doing it for obs it will not work as it can't find locale\eng-US.ini and failed to load locale but file is there.

So thats how you would set your affinity settings splitting 8 cores into two 4 cores

Am using windows 10.

You want to use 0,1,2,3 for the game and 4,5,6,7 for obs.

Only thing is that it does not save the settings of affinity after you exit the game it will return back to 8 cores when you start the game again.

So if anyone knows how to Save the settings then please post here as i have hunted on the net for awhile now.
