tscsyncpolicy

Does anyone have any idea what exactly this bcdedit command does? there are 4 of its states:
1) Deletevalue (def)
2) Legacy
3) Default
4) Enchanced
From what I learned: it does not work in conjunction with the useplatformtick command

These are usually used for debugging only, even enable platformtick is controversial, it makes your mouse more precise, because it won't use synthetic timers and smooth timer resolution window to 0.5ms e.g. instead of 0.496. Don't know why exactly! Doesn't seem relevant, as your actual mouse movement will happen somewhere in-between. And this is not actual counter for timing events, but multimedia timer for updating code to the cpu: https://www.codeproject.com/Articles/12 ... s-Tutorial I use only disable dynamictick! As all other options felt worse on 2 computers! https://www.tweakhound.com/2014/01/30/t ... nchmarked/ Article says very little info exists!!!

This is website of a computer scientist and tweaker: https://sites.google.com/view/melodystw ... authuser=0
She recommend to enhanced tsc and platform tick on, on tweaked systems. Try timer bench to benchmark your timers, but at the end it is about how it feels to you best!

FOR POSSIBLY BETTER INPUT BUT WORSE FPS
