I am using latencymon to measure latency:
CONCLUSION
_________________________________________________________________________________________________________
Your system seems to have difficulty handling real-time audio and other tasks. You may experience drop outs, clicks or pops due to buffer underruns. One or more DPC routines that belong to a driver running in your system appear to be executing for too long. One problem may be related to power management, disable CPU throttling settings in Control Panel and BIOS setup. Check for BIOS updates.
LatencyMon has been analyzing your system for 0:03:30 (h:mm:ss) on all processors.

MEASURED INTERRUPT TO USER PROCESS LATENCIES
_________________________________________________________________________________________________________
The interrupt to process latency reflects the measured interval that a usermode process needed to respond to a hardware request from the moment the interrupt service routine started execution. This includes the scheduling and execution of a DPC routine, the signaling of an event and the waking up of a usermode thread from an idle wait state in response to that event.
Highest measured interrupt to process latency (µs): 1933,599592
Average measured interrupt to process latency (µs): 2,282253
Highest measured interrupt to DPC latency (µs): 1931,840175
Average measured interrupt to DPC latency (µs): 0,843368

REPORTED HARD PAGEFAULTS
_________________________________________________________________________________________________________
Hard pagefaults are events that get triggered by making use of virtual memory that is not resident in RAM but backed by a memory mapped file on disk. The process of resolving the hard pagefault requires reading in the memory from disk while the process is interrupted and blocked from execution.
NOTE: some processes were hit by hard pagefaults. If these were programs producing audio, they are likely to interrupt the audio stream resulting in dropouts, clicks and pops. Check the Processes tab to see which programs were hit.
Process with highest pagefault count: csgo.exe
Total number of hard pagefaults 4979
Hard pagefault count of hardest hit process: 2764
Highest hard pagefault resolution time (µs): 341822,513173

I tried to switch most of my cotrollers to msi mode:
Sata i had already, but i have to installed intel rapid storage technology and it switch it automaticaly to msi mode, but storport.sys didn't better latency and addiditionaly iastor.sys start to show in latmon and make more latency, even i read, that it is crap, after i unistalled and it switches back to ms sata ahci cotroller i could feel difference, with my mouse movement, it felt faster.
And what about usb i had here
Intel(R) 7 Series/C216 Chipset Family USB Enhanced Host Controller - 1E26 latest version and same it refused to switch, to msi mode.
Now i have here microsoft standard enhanced pci to usb host controller, from 2006, because last controller dissapeared from my system after i blocked it in gpedit.msc, after i allowed all drivers again, it starts to show in device manager this...
So i start to search for driver for this and it took me to intel engine management, after i installed it microsoft driver from year 2006 standard enhanced pci to usb host controller still persist and i didn't update, dont know why.
Sorry it is tough for talk about it, for me, i am completely confused with drivers.
All i need fix somehow, someway usbport.sys, nvlddmkm.sys and ndis.sys.
I have intel gigabit ct desktop adapter i downloade latest drivers from https://downloadcenter.intel.com/download/21642/Network-Adapter-Driver-for-Windows-8- , which is from 06/02/2015 and in device manage it shows 19.6.2013
Ndis.sys i tried to fix by tuning nic, switching of interrupt moderation, iner frame spacing, flow control, or rss enable/disable, nothing had any impact off or on.
Also i tunned my neths int tcp show global setting:
here is my get-nettcpsetting
unfortunately windows cant switch to custom mode and it doesnt allow modify initial congestin windows and del ack tick timeouts, so default template is internet.
I explorer thousand sites and write to 100 forums and i wasn't able find anything usefull.
I can't play cs go, because i am ovewflowed with latency.
Sorry for ripped english.
If you had some genial ideas tell me, thanks much.
