HUGE dpc latency problems, MAXIMUS VII HERO

[LiMpIch]

This is my first post here so bare with me.
I recently got myself a new PC, whenever i run a game the DPC latency becomes enourmous. I've updated every driver i could find and have reinstalled windows countless of times, and yet it keeps reappearing.

I'm desperate and don't really know where to look for help anymore, not even the tech support from where i bought the PC have
any clue what the issue is.


Here's a picture of when im simply iddling without moving the cursos.

Seems alright to me atleast, still seems abit high but definately not ruining my experience in winddows.

This is how it looks when i'm running a game, ( dota 2 here for example.)

It's simply crazy, and i have no bloody idea how to solve this problem, any assistance would be greatly appreciated.

Hi LiMpIch and Welcome to ROG. This is taken from an article I discovered.

How to trace and fix DPC latency

First of all, any action you take is at your own risk, don't do anything you aren't sure of, always do your research first before any actions!

Begin with the basics and update your Windows and hardware drivers then properly clean up your PC
Use the tool in the link below to trace DPC delay precisely into single driver files: http://www.resplendence.com/latencymon
Disable High Precision Event Timer (HPET) in BIOS

* Note: If you're using an Asus motherboard the HPET is enforced, so skip this fix and proceed to the one below.

Timer Resolution (this little tool decreases my DPC latency quite nicely)
TimerResolution is an application to change the resolution of the default windows timer.
The standard timer on Windows 7 can vary between 10 and 25 milliseconds. Therefore if your code uses a timer or sleep value less than the timer resolution on your system you won’t be getting the results you expect. http://www.lucashale.com/timer-resolution/

ACPI Power Management: Balanced power modes etc. may cause CPU throttling which slows down your CPU so set all your power management options to full performance and look into how you can disable CPU throttling on BIOS.

Also, check into the link below for more info about ACPI.sys
http://www.techtalkz.com/windows-xp/10281-acpi-sys-causing-very-high-cpu-usage.html#post42863

Networking devices are often known to cause DPC lag,

Disable WiFi/networking/LAN devices one at a time to see if it has any effect, there might be a hardware conflict causing latency.

Unplug different devices you have plugged into your system, even something minor like an USB mouse plugged into a USB extender may be causing your latency to increase
It is quite common for different video card drivers and even BIOS drivers to act up and give out different performance, you might want to try out various drivers for your video card and updating the latest BIOS drivers.

Also review this thread: http://www.overclock.net/t/1441383/dpc-latency-constant-stutter-all-games-affected-fps-ok

Hope this helps. MM

I'm afraid i've done everything you've listened already...

my nvlddmkm.sys is constantly on 3MS in latencymon lol... it even spiked to 60 ms, i'm seriously out of ideas any help would be appreciated.

Can you just try the following?

• Uninstall AI Suite III, then run the cleaner to remove all the left over services : http://rog.asus.com/forum/showthread.php?34503-AI-Suite-III-Cleaner
  
• Boot into safe mode, open your Device Manager, open the System Devices tree right-click on AMDA00 Interface and select Disable. (Do not uninstall it.)
  
• Reboot back to Windows and how is your DPC Latency then?

A follow up to this, do you own Front Base Panel?

Uninstall ROG Connect Plus and the Front Base Panel Driver as well, reboot and monitor your latency.

Ibelieve that AI Suite III as well as the combination of ROG Connect Plus/Front Base Panel driver is causing high DPC latency. At least I found this to be true in my case.

Yup. There was no option to just disable the AMDA00 driver though so i had no other choice but to uninstall it .
My Latency is still as huge as before when running basically any game 😜 This is icnredibly frustrating, i might just break something .

I dont think i have any ROG connect installed?

[TheRealWitblitz]

Did you run the cleaner? It's my belief that either the ROG Connect / ROG Connect Plus or the Services installed by AI Suite III is the cause of high DPC Latency on some ROG boards.

Re-install the Probe II Sense driver, make sure AMDA00 is installed under normal Windows conditions. Reboot safe mode, disable it then. Did you uninstall AI Suite III?

Just asking.
