    So what was the solution? By "adjusting Virtual Pagging file" several things can be assumed...

    Of course,adjusting virtual page file initial by 1.5 of my ram and max a bit higher then initial,for about 200 mb. And yes pagging file is for C drive (system drive),i got only one hdd,but 2 partitions. I cant understand yet how pagging file can be related to audio stuttering,gpu usage,in game preformance,and cpu usage...The pagging file was mine last hope xD so i didnt change that till yesterday,because i didnt saw any relationship between pagging file and all problems related to pc such as: cpu spikes,usage,gpu usage,and audio problem...

    My solution was 32GB of RAM, and no paging file. :)

    My rig now has 32GB and I have not disabled page file - zero benefits.

    Can someone explain me if there is any advantage in turning all the devices enlisted in MSI tool to MSI mode (even for that has only Linebased as supported mode) ? It's important to do a restore point before?
    I've only changed videocard and HDaudio drivers with no apparent problems.

    Do not touch devices with "Msi" or "MsiX" modes.
    As for advantages - devices in MSI mode should handle interrupts a bit better, Sometimes that "a bit" solves minor issues like audio pops and stuttering.

    I have everything ticked (enabled). Everything set to high interrupt priority.

    Of course this might not apply to everyone and you should listen to what mbk1969 suggested, only use it where you need it.

    But in my case, if the device does not support MSI mode, it won't switch. For example I have PCI to USB host controller ticked (enabled), but it remains running in Line Based, and not in MSI. Everything else is running in MSI mode.

    You are lucky to not have boot device (SATA controller, video card) supporting only legacy mode - after ticking such device into MSI mode and rebooting you would start a training course of troubleshooting. :cool:

    a bit OT... but would you recommend disabling memory compression and page combining with 32GB?

    I would - to eliminate CPU load related to both features. (And with 16GB too...)

    If anyone interested, I did a throughout testing on whether MSI mode in any combination reduced stuttering, so that frametime is smoother. In my setup I sometimes use multi-monitor setup, and sometimes single monitor (gtx 780, i5 5770k), and in that case I couldn't find an option that would suit both alternatives.

    Individually some things worked a bit better than others, but neglectible compared to not using it at all (e.g. 0,1-0,2 ms less deviation from mean in some cases).

    Okay so just to be safe for future reference when I upgrade my PC. I should not tick anything that ONLY says "Line Based". But I can enable all the items that support MSI mode yes?

    Yes.

    But just a day ago Windows Update did update a driver for my WIFI card, and despite stating MSI mode the driver refused to work in MSI mode. So I did rollback it. So such scenario is possible.

    You do not have to enable MSI mode if your rig works fine. You simply can enable it.

    If you do not you use NVMe controller then you can disable it completely.
    If you do not you use SATA controller then you can disable it completely.

    And you can enable MSI mode for all devices since they all support it.

    Reason why im here its weird micro-stuttering/lag in CS:GO and at other games at hard action moments.
    I'm trying to fix it too many time yet. So seems like i need your help ;)

    Actually i'm using NVMe(as 960 EVO) and SATA (as x2 HDDs 7200rpm). What you can recommend to do in MSI utility? I mean different combination or something like that.

    Almost all devices are already in MSI mode. Do not toy with priorities.

    If your rig has issues only at hard actions moments then I assume it is overwhelmed, CPU most probably. Or network card. Have you optimised network stack?

    Is there any possibility to go wrong with this tool? I have "ticked" all entries. Rig seems fine. I suppose if something shouldn't have been tempered, it defaults by not using the changes at all, am I right?

    Not quite. You were at risk of BSOD at boot if there were boot devices incompatible with MSI mode.
    But beside that - yes, you can always untick any device should it glitch in MSI mode.
