Kernel timer latency?

[Slender]

Weird stuff, I normally get 12k+ on latencyMon, when I keep DPC checker on, it goes down to 500, and when I have ISCL intelligent list standby cleaner on at the same time, it hovers between 25-50 sometimes spiking to 500.

Can't quite explain it, but I think my mouse somehow feels better? I'll do some latency measurements using my 1k fps camera and see how that goes tomorrow.

What system?

z790, all e-cores enable in bios, disable in OS.
Default bcdedit (only disabledynamictick), 22h2.
This is sweetspot 0.999 timer.

2.5 years intel can't fix timer.

I set it to 0.5, and it gives me 0.4966 using ISLC

if you set 1ms, what value islc or timertool v3 show?
any bcdedit settings?

If I set it to 1, it gives me 0.9983 and gives me slightly worse DPC latency on the latency checker, though slightly more stable I think?

my am4 have 0.9996 timer.
hmm, am5 change it to 0.9983, strange.
0.9996/0.9999 best timer pick, always stable.
try to use for test:
bcdedit /set useplatformtick yes
it lock timer to 1000/500, but use RTC tick.
