DPC Latency HELP PLEASE!

[Nivek]

I am new here, and not 100% if i'm at the correct section. I hope i am, but yeah, i am having problems with my DPC Latency since a really long time. I tried alot of things to try to fix this. I have some screenshots to show you.

The weight of ntkrnlmp.exe is really huge, and i'm mostsly 100% this is the issue. I looked at the DPC Latency tutorial, and i went to your Driver Reference Table to see what driver i had to update. It said, Windows Update, but all of my things are updated already. I am really confused, i need help. I can't play games anymore!!

I hope someone will have the answer to my problem..!

To properly troubleshoot issues with high/frequent DPCs/IRPs, we require a XPERF trace. Please follow these steps to generate one:

1. Download Windows Software Development Kit (SDK) for Windows and run the setup.
2. Select Windows Performance Toolkit feature (all the others can be unchecked) and proceed with the download/installation.
3. Once the installation finishes, open an elevated Command Prompt by right-clicking on CMD.EXE shortcut in your start menu and selecting Run As Administrator from the context menu.
4. Type the following command, which will start tracing, in the Command Prompt window you just opened:
   

   xperf -on PROC_THREAD+LOADER+PROFILE+INTERRUPT+DPC+DRIVERS+POWER+IDLE_STATES -stackwalk Profile -BufferSize 1024 -MinBuffers 256 -MaxBuffers 256 -MaxFile 256 -FileMode Circular

   If you see a yellow warning "xperf: warning: This system is not fully configured for x64 stack tracing" after running the above command, please complete these extra steps (otherwise, proceed to the step #5):
   
   Read More:

   1. Run the following command which will stop the tracing:
      

      xperf -stop

   2. Run the following command to enable stack tracing (by disabling Paging Executive):
      

      REG ADD "HKLM\System\CurrentControlSet\Control\Session Manager\Memory Management" -v DisablePagingExecutive -d 0x1 -t REG_DWORD -f

   3. Reboot the computer
   4. Once computer reboots, proceed from the step #3
   If you see a red error "xperf: error: NT Kernel Logger: A device attached to the system is not functioning. (0x1f)" after running the above command, please complete these extra steps (otherwise, proceed to the step #5):

   1. Run the following command to disable Driver Verifier, which causes the above error:
      

      verifier /reset

   2. Reboot the computer
   3. Once computer reboots, proceed from the step #3
   
   If you see a red error "xperf: error: NT Kernel Logger: Cannot create a file when that file already exists. (0xb7)", please do the following (otherwise, proceed to the step #5):

   Make sure you do not have any programs that capture ETW data already running. Some examples of these are:
   
   

   • Process Explorer
   • Process Hacker
   • Resource Monitor
   • Process Monitor
   • Latency Monitor
   • Another instance of XPERF or WPR
5. Perform some activities with your computer for few minutes, making sure the issues you reported are reproduced.
6. Run the following command, which will stop the tracing, in the command prompt window you already have opened:
   

   xperf -stop -d C:\CPU.etl

7. Compress file C:\CPU.etl
8. Upload the compressed file to a file sharing service (e.g. OneDrive or DropBox).
9. Share the download link here.

Thank you.

The issue is in the network sub-system. Installing the latest driver (Win7 and Server 2008 R2 Auto Installation Program (SID:1719463)) for your Realtek network card from here should solve the issue. In case it does not, try also upgrading (or removing) Bitdefender, as it seems to be filtering your network traffic.

It did not work, i tryed to uninstall Bitdefender, nothing changed. I'm really confused, i'm gonna show you a video of what is happening with my game. Alot of peoples told me it is my CPU. https://www.youtube.com/watch?v=GHaUkPlkJcM#t=12 .. You can see at a point the mouse get stuck. That's what i'm trying to fix on every games..
