Ive never seen "gamebarpresencewriter" in my Latencymon reports, only some Nvidia kernel crap, and now Lmon looks fine after playing couple of rounds
I'm at 800 dpi currently with 1000 hz polling rate, haven't installed Logitech software yet, dunno I tested again moving with keyboard only and game was pretty fluid and 1% 0.1% looked normal (above 200), when I start flicking or pressing mouse too fast or something fluidity comes away and theres comes the choppines and "microstutters" (I'm not sure its a correct word to describe it since I have never had any stutters, not in last 10 years at least).
Is there something with the mouse, polling rate, sensor, or its just too old (guess I bought it in 2018)? Or with USB ports/hubs in MoBo? Don't have any spare gaming mouse also, only some cheap $10 office mice.
Buddy, 52.920us on your wdf driver IS NOT GOOD. You have some serious driver issues as a bare minimum. Your wdf driver is your mouse/USB driver and this should never spike above 3-5us. I've never seen a spike that high on the wdf/USB driver.
Open up the drivers tab and look on the list for the wdf driver. It will show your average dpc latency for that driver and it should be in the range of .02-.035us average. Post back a screenshot of the driver tab results.
Is your power plan set correctly? USB select suspend needs to be disabled. Also, just because your wdf/USB driver is spiking doesn't mean your USB driver is faulty. Faulty audio/nic drivers can also significantly impact your wdf driver I'd focus on fixing this first. I'd start cancelling our variables to see what's responsible for spiking your wdf driver. Run latency monitor and while it's running, open device manager and disable your nic first. If the wdf latency corrects itself you know you have a faulty nic driver. If disabling your nic had no impact, disable your audio device driver next and see if that corrects your latency. Find the culprit then try different driver versions.
Also, you need to make sure all power saving and throttling mechanisms are disabled in your bios. I see prior comments in this thread that explain this well. These need to be disabled, otherwise you won't get accurate dpc latency readings via latmon.
Can you also click on the stats page and screenshot that as well. It will show average overall system latency.
Edit: I scrolled up and see you already posted screens of the driver and processes tab. I can tell you your system latency, not just wdf, is fucked. Yes, these readings are consistent w/ the problem you described. Gameplay will be abysmal w/ latency this high.
When I see latency this high it's almost always because the bios has not been optimized properly . Disable PSS (and cool n quiet), c-states, thermal throttling, etc. Can you take a picture w/ your phone showing you disabled these settings? It looks to me like you haven't. There was a prior comment in this thread with good bios optimization suggestions. Follow those. Make sure your devices are running in MSI mode, primarily your gpu and USB controllers. Run timer resolution or ISLC and set timer resolution to .5ms. Keep this running while you game. I'm having trouble believing you did all these things and still have latency issues like that.
I'd also consider downloading power settings explorer, Google it. Open it up and scroll down to the CPU settings. Untick allow throttle states and idle states. After you do this, close this app and go into your power plan advanced options and scroll down to CPU settings. Disable allow throttle states and idle states. Once again, make sure USB suspend is DISABLED. Run latmon again and post results. Also, disable xmp and run memory at stock native speeds and see if this has any impact on your doc latency. Faulty or incompatible memorycoukd also be a potential culprit.
