If you're noticing normal or microstuttering, I'd suggest going into your bios and disabling 'df cstates.' This is a power savings feature specific to the fabric controller.
My theory is that when gaming loads are light, the IF tries to converse power and then when it's trying to wake up and can't recover fast enough, you get stutter/micro stuttter.
There's no notabable power draw by having it disabled. The good news is that cores (global cstates) are able to recover fast enough that I couldn't identify any issues caused by having that setting enabled. You also need global cstates enabled to get the chip to boost properly for light workloads.
So summary for a smoother gaming experience:
- DF cstates - Disabled
- Global cstates - Enabled
