Game is using only one core 100%

Hello there why is the game using only one core and its 100% of its usage ? I have try the method maxResourceThreads from 1 to 4 but it seems its not working
My system is:
Model X556UQ
Windows 10 Home x64
Processor: Intel® Core™ i7-6500U CPU @ 2.50GHz, 2592 Mhz, 2 Core(s), 4 Logical Processor(s)
Adapter Intel® HD Graphics 520
Adapter NVIDIA GeForce 940MX 2048 (VRAM)
Installed Physical Memory (RAM) 12.0 GB

It’s probably using more than one core, but one of them is doing the main work. Anyway, try out [Tool] Core Switcher - Force GD to use all cores equally!

You mean the Set Affinity man i never thought of that, i will try it out and see how it goes.
