you not need any of that settings.
Mine stays at 1005us to 1503us when a game or web browser is opened, when nothing else is running it goes from 14-500usSlender wrote: ↑11 Apr 2024, 14:54you not need any of that settings.
windows 11 uses RTC-tick by default.
for me, use disabledynamicktick in w11 cause problems with kernel timer (it stuck 983 us, without 0-3). same with useplatformtick yes.
w11 not need any bcdedit
upd: ahh, you set NO for DDT, i will try it.

games call for a 1ms timer, but i have it set to .5034 like you recommended, is it possible the game is overriding the custom timer ive set?
when you use useplatformclock with hard disable hpet you get ACPI PMT Timer with stable 3.58Mhz.Gadzzaa wrote: ↑23 Nov 2024, 10:07Sorry for reviving the post. I got some interesting feedback.
12600k - 5.1Ghz + 3900Mhz Ram and a gigabyte Z690 UD DDR4 motherboard
All tests are done in TimerBench1.5 and Windows 11 24H2
HPET is enabled in BIOS:
bcdedit /deletevalue useplatformclock > 10Mhz (Invariant TSC)
bcdedit /set useplatformclock true > 19.20Mhz (HPET)
Disabling HPET in BIOS + bcdedit/set useplatformclock true > 3.58Mhz (Unknown)
Haven't tested any games yet but will update this post if i come into any issues.
Would ACPI PMT Timer not be better than Invariant TSC since it has a lower Mhz?Slender wrote: ↑23 Nov 2024, 15:34when you use useplatformclock with hard disable hpet you get ACPI PMT Timer with stable 3.58Mhz.Gadzzaa wrote: ↑23 Nov 2024, 10:07Sorry for reviving the post.

you dont need use any bcdedit in w11.
(only globaltimerres reg + set 0.5033 (or 0.5034) timer)
i feel it more smooth but bad responce vs tsc.Gadzzaa wrote: ↑24 Nov 2024, 11:20Would ACPI PMT Timer not be better than Invariant TSC since it has a lower Mhz?Slender wrote: ↑23 Nov 2024, 15:34when you use useplatformclock with hard disable hpet you get ACPI PMT Timer with stable 3.58Mhz.Gadzzaa wrote: ↑23 Nov 2024, 10:07Sorry for reviving the post.
