Diagnosing Windows 10 DPC latency

[davros303]

Hi all,

Hoping someone can assist with the diagnostic process using Windows Assessment Console. I have researched and implemented dozens of Windows 10 tweaks to disable non essential features and processes, installed latest drivers for all components, but nothing has shifted. The 1394ohci driver for my PCI-E firewire card consistently appears at the top of the list. I've scoured the web and it appears there are no official Windows 10 updates for the driver for the Texas Instruments chipset (the current driver I'm running is dated 2006). The other common culprits are dxgkrnl.sys and nvlddmkm.sys (both related to Direct X and NVidia graphics drivers I believe). 

Cheers,

Davros

Seems like a normal behaviour.

I have a PCI-E x1 USB 2.0 card (not USB 3.0) for 98SE, and the driver for it (USBPORT.SYS) is also at the top of my DPC list, as well as dxgkrnl.sys and nvlddmkm.sys, as I have a NVIDIA card as well.

Nothing to be worry about, the only way to remove this is to either disable the Firewire card in Device Manager or remove such card.
