I have this stuttering problem too when I play The Division 2 and Dead Space Remake. My motherboard is Gigabyte and my Windows 11 was installed on SSD SATA.
My games performance improved after I disable the Hyper-Threading in Bios under CPU and the best thing is that I don't have to disable any of the stability option from Aida64. Maybe you guys should check if your motherboard and CPU supports Hyper-Threading and try to disable it. See if it helps.
UPDATED: After a few days, the stuttering came back. It seems that disabling the Hyper-Threading also causes the stuttering.
