Extraordinarily high DPC latency

[finermeerkat137]

My computer has been lagging and stuttering ever since I built it 1 and a half years ago. I decided to see what the problem was and got latencymon. I downloaded it, and it turns out that ntoskrnl.exe has a DPC latency of 237728.598611 . Sometimes, dxgkrnl.sys also like to join the party, with high ISR routine execution time. I've tried installing new network drivers, nvidia drivers, and clean install of windows, to no avail. I'm getting desperate now, to the point where I might just try to sell off what I can and build a new system. I've replaced the ram, mobo, tried iGPU, and took out the WiFi adapter. I've already tried many other forum posts, but none of them worked. Anyone know whats up?

 

R5 2400G

EVGA RTX 2060 XC single fan

B450 tomahawk max

16GB Patriot viper ddr4 2600 XMP'ed to 2400

256GB 970 Evo Plus

2TB Seagate BarraCuda 7200 RPM

ASUS 2.4 & 5GHZ Wi-Fi card (not currently installed)

500W Enermax revolution duo

WIN10 64 bit

 

Edit: Just ran another latencymon, and now it's nvlddmkm.sys  sometimes it switches between the two. Put in speccy for good measure as well

Hello, I had the same issue and rolling back my drivers seems to have helped a bit. I'm using a 3700X and a GTX 970. Using the 419 drivers it's a lot better.

 

Did you ever find a solution to this issue?

No, nothing yet  Disabling HPET seemed to help a bit, and switching the GPU to MSI interrupts also seemed to help, but Nvidia really needs to get their heads out of their butts on this one. I guess I just pulled the short straw, and since so few people are having this issue, it isn’t economically viable to spend resources helping them.

Sorry to hear that man. Mine seems to be slightly more in check, I used to have those crazy spikes but so far I haven't had any over the past few days.

 

Try: Enabling max performance in nvidia control panel power settings

Using the Intelligent Standby Cleaner List (software)

In MSI Tool set the GPU to enabled but undefined
