How to limit CPU usage by BuildSoftServer.exe

Start Diamonds and close it again.
Go to My Documents > Diamonds > {latest version}
Open the file Diamonds.ini with Notepad.
Look for [TMainForm_PREF] (You can use the keyboard shortcut CTRL + F to start the find function)
Add a line with CPU=*number of logical processor*
The *number of logical processor* is the binairy sum of the processors you’d like to use.
Each bit represents a processor:
1 = processor 1
2 = processor 2
4 = processor 3
8 = processor 4
16 = processor 5
32 = processor 6
And so onFor example: if you only want to use processors 2, 3 and 4, you add the line CPU=14 below the header [TMainForm_PREF] in Diamonds.ini. CPU = 14 because 14 is the sum of 2, 4 and 8.
How high you can set the number of logical processor depends on how many you have (Control Panel > Device Manager > Processors)
Save the Diamonds.ini.
Start Diamonds again.
