DPC latency checker shows latency:
Is this a hardware problem somewhere?
msinfo32 shows IRQs Ok.
I am using win10x64.

It looks like you have created a second account, which will also interfere with your ability to comment within your thread and to accept an answer. See How can one link/merge/combine/associate two accounts/users? and/or I accidentally created two accounts; how do I merge them? for guidance on how to merge your accounts.
– DavidPostill – 2017-06-24T13:17:50.883Did you try to disable devices like described in the manual? http://www.thesycon.de/eng/latency_check.shtml did you try to alter powermode settings of OS and Bios?

Install the WPT (part of the Win10 SDK: https://developer.microsoft.com/en-us/windows/downloads/windows-10-sdk), open a cmd.exe as admin, run the following command: wpr.exe -start CPU && timeout -1 && wpr.exe -stop C:\DPCusage.etl. wait for 60s of the DPC issues, go back to cmd, press a key to stop tracing. zip the DPCusage.etl and share the zip
– magicandre1981 – 2017-06-24T17:22:40.777Wow, is that thing saying it takes 1000 uS to execute a deferred procedure call scheduled from an interrupt handler? That seems like a very long time. Or does DPC mean something else here? – psusi – 2017-06-25T01:17:13.353
have you captured the trace? otherwise we can't help you – magicandre1981 – 2017-06-27T15:41:49.190
