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.

 

Permanent CPU Affinity ? without installing/running more software [SOLVED]

I cannot Edit the old thread...

Permanent CPU Affinity ? without installing/running more software

Answer was very easy... Works with all software that does Not Run in Administrator Mode...

Some softwares in Administrator Mode will Override the settings.

depends on the software.

just create a .bat file with the same name of the software in the same folder..

for example:

software.exe

software.bat

inside the .bat file:

-----

Code:

@echo offstart /AFFINITY 0xHEX software.exepause----

pause is just in case, the software gives an error, you can see what is it, but Not required if the software Works.

replace HEX with a real Hexadecimal Value of the # of Cores.

for example:

Code:

Hex 0x1 = core 0 "in TaskManager"Hex 0x2 = core 1 Hex 0x3 = core 0+1Hex 0x4 = core 2Hex 0x5 = 0+2Hex 0x6 = 1+2Hex 0x7 = 0+1+2HEx 0x8 = 3Hex 0x9 = 0+3Hex 0xA = 1+3Hex 0xB = 0+1+3Hex 0xC = 2+3Hex 0xD = 0+2+3Hex 0xE = 1+2+3Hex 0xF = 0+1+2+3Hex 0x10 = 4etc...

Windows Calculator has Programmers Mode + Basic. (Alt+3) (Ctrl+F4)

Click Bin,

type the Cores/Threads you want, in Binary, for example: 10101010 or 01010101

Click Hex to convert the values from Binary to Hexadecimal.

Software Works in Hexadecimal, but Hardware Works in Binary.

some softwares that have built-in --AFFINITY and --Threads in the command line, also needed.

Almost No Software has that.

----------

Code:

start /AFFINITY 0xHEX software.exe --affinity 0xHEX --Threads #

----------

create a shortcut for the .bat file.

Run the .bat file.

can also be a .cmd file.
