Crazy High DPC / Measured to interrupt latency

Hello Everyone

Was streaming some games today (it happens when i'm not streaming also, got to the point where it was just too much today) and had latencymonitor on for the last 7 hours or so, and have noticed that my DPC latency (especially for WDF01000.sys, dxgkrnl.sys, ndis.sys. amongst a few others) was way high! as seen in the attached pictures, I've done a few things to reduce the issue such as reverting a driver or so which has partially helped (especially for storport.sys which isn't a problem now)

but apart from that I don't know what to do now, any help would be greatly appreciated :) latency results 2.jpglatency results 1.jpg
 
Hi xilolee, thanks for the welcome :)

apart from the above (which is frustrating), some reason during any game, every few minutes or so (sometimes even less) screen freezes up, and during that time the gpu dips from 95+% to 30-40% before going back to 95% which then the screen unfreezes and the games playable again, maybe a few stutters as well.


Honestly suprises me how peoples system get amazing low latency times :P
 
I've Read the topic, i'll have all the results generated and posted here tomorrow.

Thanks for replying!
 
Does the problem happen even without internet connection?
Are you using F4-3200C16D-16GVKB (2 x 8gb) ?
Try to set the ram speed to 2166 (in your bios settings).

It happens less on single player games (without internet connection) I gave a few games a test on their single player mode (Rocket League, NFS Payback) and there may maybe 1 freezeup of the frames on screen, not very noticable, but noticable.
i'm using F4-3200C16S-16GVK (red as opposed to black ram)
I've changed the RAM speed to 2166 now, still seems to happen but just not as often.

I could do a trace for when i'm playing online and then a trace for offline if you like?

It definitely feels better, but don't want to say for sure, since the massive fps drops/freezes could take their time to show up, and i only spent maybe 5-10 minutes on each game to test.
 
Sorry, I wanted to write 2133. Or 2667.
Was you able to set it to 2166?
Try to run a game (the one with most problems, possibly) without internet connection.

Problems feel a little persistant, also the traces im collecting aren't as big as a file as the ones i just sent you, i ran 'xperf -on DiagEasy' for 30 minutes and it was only 4mb. Am I doing something wrong here?
 
I've also got trace files working again, how big should the trace file be if I do a trace for 30 minutes?
 
Mine has got less than six months (and maybe I already cleaned it once): can you see the dust in the heat sink?
Fans are working (I did this photo some minutes ago).
