input lag on newer pcs

[ayoo]

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..

So for me personally, Alder Lake has been an absolute nightmare, primarily because mouse feel and responsiveness constantly changes from day to day. I'm starting to strongly suspect and believe that input lag/responsiveness issues w/ Alder Lake is DDR4 incompatibility.

All of my kits are samsung b-die and not a single one of them run properly on xmp. XMP just doesn't seem to work. I have to make adjustments to system agent, dram voltage, training voltage and even termination settings just to get XMP to boot and when it does boot, the mouse can feel great one moment and then feel like it's in mud another moment. What I noticed in my situation is that my RTLS are constantly changing, so memory training just appears to be broken as well. Once I found good rtl/iol settings I'd try and lock them in but my mouse feel was always changing. Games also don't feel great at high FPS. The game just feels like it's in mud along w/ movement and mouse feel when it's misbehaving.

I strongly suspect Alder Lake issues stem from ddr4 incompatibility. You can't even get kits to run in a stable fashion @ or above 3600. I switched from a 5800x which I think I'm probably going to go back to in the short run. I also still have my 9700k/mobo I may even go back to as well.

It's probably the game server you're playing on and nothing to do with your PC. I've noticed very strange mousefeel on game servers where there are lots of cheaters/hackers in the server - apparently the hacks/cheats they use end up in the server having increased CPU usage and the server gets bogged down, which affects things like mouse feel in the game. It happens on my old PC which is a 6700K CPU, so it's nothing to do with new generation CPUs. I don't know for certain if it's the server causing your problems, but I think it's likely. Probably the same for everyone in here.

Hey Brah, did you solve this by changing your mobo and RAm from DDR4 to DDR5?, just let know everyone who enters this forum, yes, this is an issue with Alder Lake, I have literally the same symptoms with a high-end B-Die DDR4 (4000 MHZ 14-15-15-35) on a 12700 kf, the performance is quite awesome, but the input lag is just a nope nope. I upgraded from a 6700HQ with a 1030 mobile with Optimus enabled as default, I had like 90 ms of input lag most of the time, and input with Alder Lake with DDR4 MUST be higher, but weirder since the system is stable and smooth with good performance. I'm just unable to use this since I built this specifically for competitive gaming, the sadness bruh.

I managed to solve the issue with input lag on the 12700KF although it was a long process from my first forum comment, I had to update BIOS to the latest one rn (Asus TUF Z690 Wifi Plus D4, mod hidden bios settings (remove C-States, any power economy options and security options. Follow the guide from Ancel), OC the ram, cpu to the highest stable setup, and install Atlas OS latest playbook version, after that running Ancel Script and on top of that the Melody OS Script by Rottina, after all that im having the snappiest experience ever, but Im not gonna lie, theres always the feeling with these component that Im missing something for better performance.
