[SOLVED] Acceptable Page Faults and ISR/DPC Latency ?

[bentheblobfish]

Ive been getting stutters in many games, and in latencymon i see a max of 1200 nanoseconds (1.2 ms) DPC latency, and spikes of latency up to 1500 nanoseconds (1.5 ms) in DPC Latency Checker (Pics below; one is in game, the more consistently high one, and one is just on desktop with monitoring windows open - the one with more spikes).

I also see a high number of hard pagefaults (when loading games and such, i can see upwards of 500 page faults a second), but my 16gb of RAM passed memtest86 with 0 errors overnight.

Could this be the cause of my stutter? How can i fix this issue?

page faults are normal operations of windows. What they mean is the CPU has to access ram for information. Probably normal in a game. I don't know what an excessive amount would be.

from what i can tell latency mostly caused by sound drivers, can also be LAN drivers and I seen DPC errors caused by storage as well. Up until a few months ago I hardly ever saw them, now it seems to be all I see. (note: I solve BSOD posts here, so all the errors I have seen aren't on my PC)

looking at reports, NDIS.sys is 2nd on list. Its Network Driver Interface Controller so maybe we start there:

Do you use WiFi or Ethernet cable?
newest wifi on MSI website could be the newest Intel WIFI drivers, I can't tell.
Can run this and see if it offers any newer - https://www.intel.com.au/content/www/au/en/support/intel-driver-support-assistant.html
Ethernet - Probably newer ones here
If you on win 10, download Win10 Auto Installation Program (NDIS)
If you on win 11, download Win11 Auto Installation Program (NetAdapterCx)

Apologies, i meant Hard Pagefaults. From my understanding, it means that windows is trying to access information very quickly as if it were in RAM, but can’t because it isnt in RAM. I will run the program listed - i am on wifi.

Hard page faults are when the CPU can't find info on RAM and has to access data off storage which also makes sense if you playing a game

I tend not to get them while actually in game, and if i do they are much fewer. i get a lot when first starting the game. My PC will sometimes freeze while loading a game.

Neither of these fixed the issue. Same DPC latency.

are games on the ssd or hdd?

shouldn't freeze loading games

try running magician on ssd - https://semiconductor.samsung.com/consumer-storage/support/tools/
run seatools on hdd - https://www.seagate.com/au/en/support/downloads/seatools/seatools-win-master/

All on brand new SSD as well as older SSD ive used for a year or so now. Also tried unplugging HDD. Ill run programs and keep you updated.
