The Windows 10 scheduler issues have been present, hence we all need to follow and install every single new chipset driver release, with the hope that things might actually get fixed.
"The Windows 10 May 2019 update, combined with the new chipset driver from AMD, is supposed to improve the process scheduling (aka, the "topology awareness" that
