Xhci only on modern motherboards?!

I am not sure, if this is true for every modern motherboard. But i have 9 gen ASUS ROG STRIX Z390-gaming i and it has only Xhci USB drivers, instead of having proper Ehci drivers. I found long time ago, tested on 2 computers: USB 2 feels much better than USB 3! I disabled all USB ports on my motherboard, except USB 2, because i didn't need them. I got VR and i needed USB 3, so i enabled one USB 3 port in BIOS. And i instantly noticed, mouse movement felt worse! Even i disconnected USB 3 and only thing i have connected is mouse and keybord in USB 2. Yet my mouse movement sucks... And i noticed in Device Manager: that there are only two USB Root Hubs and at the end is written (USB 3.0), while before there were USB Root Hubs, or something like Generic USB Root Hub and no (USB 3.0) in parenthesis...

So i wanted to ask about this, if that's normal on every motherboard. Also any way i can get normal USB 2 Root Hub, when i am not using USB 3. It would be annoying to go to BIOS each time and disable, or enable it...
Also i have no p2/s so i can't try to mess around and uninstall stuff. Hard restart can corrupt system and doing that each time is not feasible anyways...

THANKS!

Good luck using VR on USB 2.0.

Third motheboard I'm using and there is literally no difference in mouse feel, no matter what settings. The only difference I felt was when I was using DVI-D to HDMI cable when I still had an old GL2250 screen, then installing SS Engine immediately create an acceleration and decceleration which should not be present, as these were set to 0 in the software.

Maybe you can't tell. There is input lag test: https://forums.blurbusters.com/viewt...=1134&start=20 I was able to tell even 6ms difference, i answered correctly 21, or 23 - from 25 times.
I was also supreme master class in cs go and top 1 master in sc2, i am not telling that to boast. But everyone have different sensitivity to these things. I was even told by psychiatrist, it is amazing what i can sense... I have good senses bro...

There is definitely difference, at least on my setup. I tried 2 computers and on both, USB 3 feels like trash...

There is no difference in polling rate, first of all. Second, the mouse operates at 2.0 Full Speed anyway. XHCI is just a newer controller API, there is no such thing as EHCI any longer. XHCI is the only proper driver. There is no functional difference, I am sorry to say that something else is causing your issue or you are crazy.

That's not nice thing to say. I even read forum post on this forum. Someone who is going on lan a lot - can tell usb 3 causing a lot of input lag and mouse feels terrible. I can tell even 6 ms difference in input lag!!! I was supreme in cs go. I am very sensitive to it. You are just one of these people, which thinks more than 24 fps is useless and between 60hz monitor and 144hz is no difference. Human eye can see even individual photon of light. Why is it so hard to believe, that people can discern input lag ???

For example, i can confirm majority of these tweaks: https://csgotweaks.com/bios.html
- legacy vs uefi difference in mouse feel
- disabling csm, improve mouse feel a lot!
and many more, listed in this guide have impact.

I doubt you are usb 3.0 engineer and even than, you probably don't know everything. There is higher latency with usb3, or something: which makes mouse movement terrible... A lot of people noticed it too btw... E.g. there is difference between usb 2.0 and ps/2, ps/2 is better until 1000hz... Don't call me crazy, because clearly you have no idea what you are talking about. How about you try input lag ab test and tell me your score ? Are you scared ? Chicken ? Bok bok bok bok bok

No, I just meant I didn't know one can be such pretentious arse. If you're bothered by the magical 6ms input lag then it's not mouse lag is terrible.

Mean learn to read ? It is app to test how much you can discern input lag. I am not bothered by 6 ms, that difference i can tell. You don't even try it and you will tell me i can't tell difference and i am crazy. Yes you are *******. If you don't have anything relevant to say, don't...

Also what may you not realize, if you have difference even 500us, but it is 144 times per second. There is actually massive difference in input lag, like using timer resolution: which updates code to cpu faster. You can set it to 0.5 us, or to 1ms and between these 2. There is gigantic difference. Also if you have high dpc latency for your usb driver. Last position won't render in next frame and you will have to wait another 6.9, or 16.67 ms, before next position renders. It scales per 1 second, if mouse doesn't update from last position, each time frame is rendered. That's actually huge deal. It wouldn't surprise me, if there was something technical, that causes mouse lag, or even different feeling between USB 2 and USB 3. I can feel difference as same as could on my old PC, so it is not coincidence and different mice. If you still believe you can't tell difference between like 60 hz and 144hz. Than you probably won't understand this at all. So if you can't tell, doesn't mean anyone else can't...

Btw don't try to flip it on me. I posted legit question and you started to flame me from start. I don't know why... i seen that in other topics too, some people talking about input lag etc. And all of the sudden random guy jumps into discussion and flames people, that they are imagining it, or something. But if you think, it doesn't matter. Than why do you care so much to answer?!

That's completely something different, that's reaction time, not how much input lag you can discern. It is from blurbusters and it is legit... It splits screen at two halfs and you have 25 trials to click on half, which has less input lag. And you can set difference between screens in ms.
