Exploring the link between C-states and latency

[nomaddroid]

Can I configure the Windows power scheme so that the processor goes to 100% in the C0 state during the game?
Currently, some nuclei are in C1 (60%) and some are in C0.
I would like to switch all cores to C0 during the game.

Yes, you could do that by disabling "Processor idle disable" setting in Windows Power Options. To unhide this setting via Registry, go to

Code: Select all

Computer\HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Power\PowerSettings\54533251-82be-4824-96c1-47b60b740d00\5d76a2ca-e8c0-402f-a133-2158492d58ad

and change "Attributes" to 2.

Be wary that running CPU at 100% all the time may degrade the performance instead. At least keeping C1 state would already cut off unnecessary latencies caused by C-states.
