In this first image Im sharing my Msinfokokkatc wrote: ↑20 Oct 2021, 12:29So most of a system's DPC latency comes from default power saving settings in your BIOS, then power savings in your OS, using good drivers, then setting all devices to MSI mode also in the OS. The results I see here tell me the system is not really optimized for low latency applications so there's probably still a lot of power saving mechanisms in play slowing you down. In my experience, updating your motherboards chipset drivers usually resolves the high CLASSPNP.SYS latency. The WDF file you see is your usb controller, so once again, update your motherboard's chipset drivers and make sure all of your devices are running in MSI mode. Google how to put your devices in MSI mode. There's a good utility out there called MSI MODE V2. After you download it, make sure to run the app as an administrator or it won't populate your devices. The important devices to put in MSI mode will be your GPU, Network, USB. You can put your soundcard in MSI mode but on some older soundcards, usually realtek, the sound may stop working in MSI mode. If that's the case, just put your sound back to default settings.VenomLolo wrote: ↑19 Oct 2021, 23:09So hop back in back4blood and felt no stutter but latency mon did this and also the latency spike inside the game was jumping from 7.1ms to 8.2ms and i believe this is a insta red flag right?

im uploading the images like this because for some reason im unable to upload them normally.
Im going back to ai optimized cores and voltage auto.
Also, if you give me your motherboard model name, I can look up the user manual and help you out with BIOS settings. You're probably missing some settings like speedstep, eist, etc. Some manufacturers call these settings different things.
In regards to the DPC latency results you see there, hitting above 200us is considered HIGH for realtime applications and gaming. Also, reaching 900us is exceptionally high and not ideal at all whatsoever. Just to give you a comparison, all of my systems after being optimized rarely hit over 50us idle and are usually in the 8-20us range, and might occasionally hit 80-100us on my DX driver (GPU). When running this test, close all unnecessary background apps so they don't interfere w/ the results.
Also, before just jumping into making changes to your system, read up on it. Get a relatively decent understanding of what you're doing rather than mindlessly trying things someone on a forum like myself is suggesting. I also recommend making a restore point before you make changes, so if you mess something up you can revert back.
Edit:
I see your motherboard now Asus Rog Strix Z490-F. Here's your manual: https://dlcdnets.asus.com/pub/ASUS/mb/L ... EM_WEB.pdf
In the manual under 'CPU Power Management Configuration,' disable: Intel Speedstep, Intel Speedshift Technology, Intel Turbo Max Technology 3.0, Turbo Mode, ALL C-STATES <-- Every single one disabled, Thermal Monitor. In regards to Turbo boost. Note: Some newer motherboards will force you to enable Turbo to OC your CPU, even if done manually. Using the motherboard's built in AUTO OC/Tuner feature is usually a bad idea. Better to do this manually and set a static clock w/ Intel chips.

On this second one my Msi mode settings

Here is latencymon running for 12 mins on idle on desktop

Here is the drivers tab on idle for 12 mins

This one is idle in game

Idle in game driver tab

This one I gamed for 5 minutes but died no stutters at all, a lot of action on screen, frames howered between 141 (locked) to 138 135 and no stutter was felt, latency howered between 7.1ms to 7.5 maybe 8ms.

Driver tab for 5 mins gaming no stutters and frame hovering between 141 and 138/135.

For some reason i didnt used any CpuZ or Gpuz or Hwinfo I just kinda stick to latencymon.
Now I will be following the other suggestions you gave me with the c states options on the bios and play again. will report back!
