Game runs sluggish on Windows 10? Easy fix

[me (real)]

Launch Arcanum, get at least on the main menu, alt tab, open task manager (ctrl shift escape), details, find Arcanum.exe, right click, set affinity, untick all cores but one (for instance CPU3).

Not sure if anyone cares / still has this issue, but I spent a week trying to fix it and found a working answer here
