High latencies potentially causing poor game performance

[Losty]

Hi everyone,

I have noticed some inconsitent gaming performance on my system and after some research have found my way here.

LatencyMon reports high interrupt to process latency (7811), while nvlddmkm.sys has high DPC execution time (750+).

I'd really like to get the bottom of this.

Here's my info and attached traces.

Self-built desktop PC
Freshly formatted and fully upadted Windows 10 1803 x64 Home
i7 4790K
Corsair 16GB (2x8) Vengeance DDR3 1600MHz (CMY16GX3M2A1600C9)
EVGA 1080 Ti SC Black Edition
EVGA SuperNOVA G2 650W
MSI z97 Gaming 7
Drivers verified
Security software is Windows default
No proxy or VPN software
No disc image tools
No overclocking except for RAM at XMP

The trace file may be small but I was working within the constraints of the forum. If necessary I can take a longer trace and upload to another website for download.

Thank you.

Hi Losty! :welcome:

No information about your ram, even on speccy.
Could you provide it?
Set it to 1600MHz in your bios settings.
New bios available: 1.C 2016-03-07 (current is 1.0).

Hello, thank you!

Ram is CMY16GX3M2A1600C9R and set at 1600mhz through XMP. The bios installed is the latest 1.C (1.12).

Then try this:

• Right-click windows start, click command prompt (admin), launch the following command:

  cleanmgr /sageset:1

  A window will be presented in which you can choose the items to delete and click ok, then cleanmgr will start to clean the drive/partition.
  I'd select them all, but you can choose to avoid some options.
  
  
• Launch the following command:

  cleanmgr /sagerun:1

  And the cleanup will start: wait until it finishes.
  
  
• Launch the following command:

  dism /online /cleanup-image /startcomponentcleanup /resetbase

  Wait until it finishes.
  
  
• Launch the following command:

  defrag c: /h

  Wait until it finishes.
  
  
• Launch the following command:

  chkdsk c: /b

  Reboot needed.
  
  
• Remove the xmp setting and set the dram frequency to 1333.
  Are the sticks seated in dimm2 and dimm4 (the second and fourth slots, starting from cpu)? If no, re-seat them.
