This is far out but do you have any USB devices plugged in? I get periodic stutters in apps which I think is because of USB mouse and USB KB.
Can you try this :
- Interrupt Delivery Mode : Full MSI (Message Signaled-based Interrupts) with MSI Utility : https://github.com/CHEF-KOCH/MSI-utility/releases/latest
- Fast Startup (Windows) : Disabled (by disabling Hibernation in cmd as administrator : powercfg.exe /hibernate off)
- Fast Boot (BIOS) : Enabled
- CSM (BIOS) : Disabled (Full UEFI)
- Secure Boot (BIOS) : Windows UEFI Mode
