BCDEDIT THAT RUINED MY LAPTOP
I need help with my bcdedits settings. Watched a youtube video on reducing latency and so on and decided to try these bcd commands:
1. bcdedit/deletevalue useplatformclock
2. bcdedit/set disabledynamictick yes
3. bcdedit/set useplatformtick yes
4. bcdedit/set tscsyncpolicy enhanced

i have been having extremely bad fps drops while playing games especially valorant. I used to get constant 165fps now it barely touches 100 and it fluctuates badly and even freezes at 3fps. I even tried to bring to 2 computer techs, they cant fix anything. I really need help fixing this. Also HPET might be disabled in the device manager. How do i bring all this back to default?

This is the youtube video i watched and followed. One of the tech has also tried to flash my windows 11 to windows 10 using a usb drive. It makes no difference, the fps drop is insane.

Hello,

Looks like those are related to timers, mostly.

I have published some useful information about timers:

I hope this helps.

TL;DR this is the default setting:
TSC + TSC without desync: bcdedit /deletevalue useplatformclock - bcdedit /deletevalue useplatformtick - make sure HPET is enabled in BIOS
