windows 8.1 - How do I permanently set the affinity of a process?

I have a game that has issues with CPU usage, so one of the fixes is to disable one core out of a quad core cpu. Since everytime I launch the game I have to manually go into the Task Manager and manually input the affinity, which sucks since the game is newly released yet prone to frequent crashes.

Is there a NON SOFTWARE solution?

I've looked up some solutions online and they seem to be geared towards Windows 7 only. Is there a solution for Windows 8.1 users like me?

Answer

You can create a shortcut to assign affinity.

X:\Windows\System32\cmd.exe /C start /affinity Y game.exe

Y is hexadecimal and is a bit mask:

0x1 - 0001 - Core0
0x2 - 0010 - Core1
0x3 - 0011 - Core1 & Core0
0x4 - 0100 - Core2
0x5 - 0101 - Core2 & Core0
0x6 - 0110 - Core2 & Core1
0x7 - 0111 - Core2 & Core1 & Core0
0x8 - 1000 - Core3
0x9 - 1001 - Core3 & Core0
0xA - 1010 - Core3 & Core1
0xB - 1011 - Core3 & Core1 & Core0
0xC - 1100 - Core3 & Core2
0xD - 1101 - Core3 & Core2 & Core0
0xE - 1110 - Core3 & Core2 & Core1
0xF - 1111 - Core3 & Core2 & Core1 & Core0
