Recently I did these commands to increase performance, they were all in windows power shell administrator:


bcdedit /set useplatformclock no

bcdedit /set useplatformtick yes

bcdedit /set disabledynamictick yes


In addition I disabled HPET in device manager before restarting.


I was not sure what my QPC was before any of this happened, but on restart  I did not notice any decrease of stuttering on browsing, maybe things got better but it was not noticeable. Checking timer bench I had an unknown QPC at 10mhz. My default ms is now 1.


I decided to see if HPET made a difference, so I did

bcdedit /set useplatformclock yes

Enabled HPET in device manager and shutdown my computer.


The next day my laptop was EXTREMELY unresponsive, my keyboard language was refreshing, and it would take forever to load applications.

I checked time bench and it showed 24 mhz and had HPET on.  My default ms was still 1.


I disabled it again with

bcdedit /set useplatformclock no

Turned it off in device manager, and restarted my computer. Everything back to normal.


Does anyone know how mhz affects your computer? How come my QPC mode is unknown but at 10mhz? Is it using TSC but not telling me? I don't see HPET in my UEFI settings, might it have been disabled already and my laptop is not compatible with it? What does ms do?
