Hello everyone,

I have a brand new PC and encounter since a few week some stuttering, even on the desktop (no game) or while running game while making sure my CPU & GPU does not go up to 99%
When it happens while I'm playing, I don't event see a drop on the framerate, just a micro-freeze / stutter.

Can you help me troubleshoot this issue ?

Hi JonathanM - welcome to Sysnative :)

From the trace I can see 2 long running storport.sys DPCs (a 98.150393ms fragment and a 3.043544ms fragment) on core 1. The DPC routine being called is RaidpAdapterTimerDpcRoutine. Those are long runtimes but they happened back to back and were part of the same "spike" so I'm not convinced they would correspond to the symptoms you described.

On core 0 there are some fairly long running DPCs (8 or 9) which were queued by nvlddmkm.sys which is a Nvidia driver. From slightly less than 1ms to slightly more than 2ms. My guess would be the stuttering is due to the nvlddmkm.sys DPCs although I don't know for sure. Can you confirm you experienced the problem during the trace?

Is this routine a 'normal' activity ?
I don't have any Raid setup.

RAID drivers are typically bundled in with Windows to allow users to use a RAID configuration if they wish. It's a internal kernel function so I'm not entirely sure what it is does, but likely just completing housekeeping tasks.

Have you updated your nVidia graphics card driver as suggested? I apologise for the lack of response from us.
