usb latency

Hi, I'm facing a strange problem. I have a B760 Gigabyte XDDR4 with a 14600KF, chipset driver up to date. I've always heard that connecting our peripherals directly to the motherboard was better for input lag, but for me it's not at all the case! It's even worse. I've tried all my rear ports and the lag is greater than if I connect them to the front of the PC. I've tried with the chipset driver up to date or not. Can someone explain this problem to me? Thanks.

Well, I think I've solved my problem, I deactivated the XMP profile, to leave my ram at 2400mhz instead of 3200mhz, and everything is better input lag fluidity, the whole system works better, I will continue to test for a few more days but I sincerely think that the problem came from XMP

Don't go by subjective feel because you are only doing what other people have done before and this won't stick. Optimize your PC correctly by doing manual overclocks and distribute background processes on E-cores.

thanks, but isn't win11 supposed to do it all by itself?

Feel sorry for you bro. I use 14600kf for more than a year now. I also thought that disabling XMP profile is a solution at the beginning. Your journey only starts here lmao. The best fix is to sell 14600kf and buy AMD cpu.

i back to 9700k from 13700k.
that is like different system about how mouse feel. Super stable polling rate while play games.
only z390, z490 can do it.

The W11 change, which occurred in the 23H2 update, is something entirely different and unrelated to this topic.
If you are interested, you can find the explanation of what the change encompasses by visiting here

Don't listen to the ignorant & vague comments which are commonly thrown around here.
A good chunk of users visiting this subforum seemingly like to misinform others with their advices, either maliciously or out of their ignorance ("tweak" sellers or just general trolls) on the topic of HW & SW.
Ignore them.
You seemingly had a situation of unstable RAM timing profile, which your CPU's IMC couldn't handle and it clearly led to ill behavior.
Majority of users which visit this subforum like to chase invisible ghosts, while many of their issues can be attributed to the aforementioned issue — general HW instability.

Hope this helps.

as kyube already said, remove all overclocks, only set xmp
reset bios settings, disable components in bios that you dont need (wifi, bluetooth, personaly i only use external audio setup and disable it on my motherboard), try different usb ports (its recommended to use the usb ports that directly go to your CPU, check mainboard manual for this information)

Try to run your pc at stock settings, also do a fresh windows install if you did any "+400fps tweaks" to your windows and make sure it's not a hardware fault

By far the biggest impact on lantency is setting up your Interrupt Affinities and also reduce your interrupts in general (you can do this in your powerplan for example by unlocking hidden settings)
For Interrupt Affinities there are several tools you can use. I use the tool "GoInterruptPolicy" since it has the best UI.
This topic is abit overwhelming at first but trust me its totaly worth the work. You basically asign every component you have a seperate core to work on. GPU gets a core, your usbhub where your mouse is connected gets one, your network adapter gets one, etc.

I haven't recommended anything in this thread, only reaffirmed what the OP did.
XMP/EXPO is an overclock, voids warranty & can be unstable depending on IMC bin, as per AMD & Intel
Read the footnotes (funny placement )

Savitarax is usually misleading as well.

XMP is just an overclock. Nobody guarantees you those are good settings btw. That's why you should always OC manually if you even know what you are doing.
