The more i read this thread and compare to my case the more im sure something is very wrong but im surprised that i hear very little about it on the internet - people dont notice things like that?
This is my thread: viewtopic.php?f=10&t=11199

TLDR im on z790 13700k and ddr5 and my mouse sttutters. Recently i discovered that i have less stuttering with wired mouse vs my wireless logitech g603 but stuttering is still present. And about input lag: i feel like it changes often, sometimes mouse movements are responsive as fk, then a couple hours later they are sluggish.

Ive read that Z690 had many USB problems, it seems Z790 has them too. New architecture on Intel processors might have something to do with it. Although i tried disabling all Efficiency Cores and it didnt help.

At this point i hate this PC so much that i want to go back to my Z370+i9 9900K+DDR4 where i could use my favourite wireless mouse and had no issues like these...
I sold all old parts so now i have to try swapping new parts, maybe try DDR5 kit from other brand with different spec..

all z690 and alder lake have timer issue, after reboot or on startup take 3!!! another timer resolution with different feelings.
Please, test it with bcdedit /set useplatformtick yes
+ default timer res (1ms), it will stable timer res to 1 or 0.5ms (i dont recomended 0.5)
thanks for update.
FYI, for my Alder Lake build I use Windows 11 since it's basically required because of the thread director. Windows 11 by default will run at exactly .5ms w/ timer resolution. Sometimes it's .503 or .496 on the first click, but it goes to .5ms by the second click w/ timer resolution. Windows 11 timer resolution has changed. Most of the time it goes directly to .5ms. Are you on windows 10 by chance? I've done A LOT of bcdedit testing over the years and ultimately decided that useplatformtick yes is bad. Even disabledynamictick yes appeared to add some kind of desync, especially on 11. Even though the mouse appeared to become more consistent, it added input lag for me. Maybe that's not the case on all builds but that was always the case for me. On Windows 11 specifically I get the best results w/ leaving bcdedit settings @ default.

I'll test useplatformtick yes for you regardless and let you know.
yes, im always say usetick yes cause lag and desync, but on alder lake its necessary.
yes, im use win10, win 11 have change with timer res.
but on win11 i have much dpc latency on usb controller.
and yes, disabledynamicktick yes ruine aim.
Hmmm, I have some thoughts on this regarding Windows 10.

My experience of Alder Lake on Windows 10 was not good. Everything felt lagged, slow, delayed, desync, etc. It did not feel responsive at all which is probably due to the fact that Windows 10 doesn't have the same thread director 11 has which was designed to deal w/ P & E cores. Simply speaking, Alder Lake was designed for Windows 11. I ran a dual boot/partition w/ both 11 and 10 installed so I could compare and 10 did yield lower DPC Latency across the board, however, the games were less smooth and input lag appeared to be higher. On 11, the games/mouse are more responsive. I've also noticed instances where my usb driver (wdf) in dpc latency was MUCH higher in 11 but still felt snappier and more responsiveness than 10. Long story short, you're going to have never ending problems running Alder Lake on 10. I would kindly suggest you give windows 11 another try because it already sounds like 10 isn't doing you any favors. Perhaps at least setup a dual boot w/ both versions installed.

Also I wanted to mention in case you were unaware, I disable all E-Cores along w/ hyper threading which significantly drops DPC latency which improves mouse feel quite a bit.
Does this applies to 12100f too ? (since no e cores) I know you have that cpu

And win11 wont let you use legacy bios ? , and force tpm ? goodbye mouse movement..
