Hi Laci,
Thank you for the input! I would say, there are some operation of Archicad that is still single-threaded, and this could be one of them. If the core that carries out this process got overloaded, Archicad may become sluggish.
In Task Manager > Performance tab, we can switch the graph of the CPU to show the load on all logical cores. Simply right-click the graph > Change graph to > Logical processors, this will show how each core is loaded. We can identify whether something is overloading one core.
Also, at the bottom of this Performance tab, there is a button to Open Resource Manager. This program will show us an even deeper look at resource distribution. But it is quite technical, I myself rarely use it.
