Recently I switched to the z690.
And immediately noticed some oddities compared to the z390. I will omit those moments that it is impossible to change FCLK and Spread Spectrum in the bios now, but there are really terrible moments that do not allow using this platform.
I have always used the standard windows timer ((useplaformtick no/useplatformclock no) /deletevalue)
with a resolution of 0.5 (0.46).
On this platform, I noticed that the timer varies on reboot, it can be 0.5 and 0.497, ok, but these are just numbers. My mouse started behaving as if I had useplatformtick yes enabled.
This happens when applications are completely turned off, and when discord and Spotify start, for example.
I also used a separate pci-e 2.0 controller for my mouse, but now it feels terrible.
And I, the same thing I observe if I insert my mouse into the usb 2.0 port on my motherboard + disable all other ports in the bios, naturally I do the binding of the controller to a separate core with HT disabled
Who has encountered?

Legacy IO Low Latency | VarStore: PchSetup, VarOffset: 0x771, Size: 0x1
Disabled: 0x0 (default)
Enabled: 0x1
Set to enable low latency of legacy IO. Some systems require lower IO
latency irrespective of power. This is a trade off between power and IO latency.
This setup option disables additional clock gating and power management functions and
should always be Enabled if it is available in the BIOS setup.

Re: Z690 usb/timer issue
Yes it should, It's one of many bios settings that are useful. I'm well read on every bios setting there is & I can tell you there's so many settings in different chipsets & different from company to company.Slender wrote: ↑21 Mar 2022, 10:11Legacy IO Low Latency | VarStore: PchSetup, VarOffset: 0x771, Size: 0x1

I find wery helpfull things
USB 2.0 Controller Mode | VarStore: UsbSupport, VarOffset: 0x2E, Size: 0x1
HiSpeed: 0x1 (default)
FullSpeed: 0x0
it is feel like my pci-e 2.0 controller
(device fullspeed and port fullspeed)
1.1 == 1.1
Re: Z690 usb/timer issue
what about legacy usb support and xhci-hand off?
for me on z390 in disable both for normal mouse control
Legacy IO Low Latency disable or enable?
