Everything about latency. This section is mainly user/consumer discussion. (Peer-reviewed scientific discussion should go in Laboratory section). Tips, mouse lag, display lag, game engine lag, network lag, whole input lag chain, VSYNC OFF vs VSYNC ON, and more!

for intel yes, it make sence
ok I bought one and testing right now
msi mode on or off?
and have u installed a driver?
only mouse or also keyboard and audio?
Is that light on your device also permanently red? I connected the power cable.
there is only non-msi mode.
there is 8 separate controller inside (4 - 1.1, 4 - 2.0), you can connect keyboard and mice.
i dont use power cable for it.
thats the one I have usb 2.0
and you havent installed any additional drivers?
yes, but i think it work better with csm mode + legacy io latency enabled (scewin setting)

Okay, I've been testing it for a week now, and you can definitely notice a difference compared to the xhci Intel USB controller, but it's still not quite the same as when I run imod on the Intel USB controller. Maybe it's because my mouse has 4k, but it's better than with the Intel USB controller without tweaking.
And I think I've found an RWEverything alternative that still works with Core Isolation. It works, but the program looks like malware

What is an alternative program to RW for disabling interrupt moderation?

yes, mcs9990 dont have it
How does the mouse feel compared to a direct connection to the CPU USB (AMD)? Does it make sense to buy a separate USB card?
amd cpu usb 2.0 > amd cpu usb 3.0 > mcs9990 > GL 2.0 > intel usb controller
for intel yes, it make sence
Wow you put intel lower than amd usb 3.0 ?
Does this applies to old gens ( 2012-2017 ) aswell ?

it applies only for new gen crap intel.
z390 and z490 last good intel with perfect usb polling rate (delta 999.9-1000.1)
