[SOLVED] DPC ISSUE, micro stuttering

Don`t you have any external hard drive or usb memory stick big enough to backup important data ?

What is the data you would like to keep ?

Can you check the size of the files because there are many free of charge cloud solutions you can use.

It`s always wise to have your important data on backup somewhere.
 
To be honest one of the people experience the same issues as you already done the reinstall and there was no change so we confirm the GPT partition will not resolve this issue.
I`m afraid the only option is to install older version of Windows or wait until nvidia and microsoft resolve this problem. I already reported the issue with both and waiting for their response.

I`m 100% sure your hardware working perfectly fine.

The other option will be to remove the NVIDIA vga for now and use the integrated video until they come with some fix.
 
update after i tried 2 game session.
after 40 or so min i think i had only 1 stutter episode, not sure if more happened ( anyway not enough to let me notice it i think )
during 2nd game session i got the notification on latencymon, here's the report and screenshots :

i hate to say this but... i think i'll give up. not sure yet...


by the way i noticed SFCFix folder in C.
do i have to keep it or can i delete it ?
 
This is close to BSOD but he Windows 10 refusing to crash rewriting on the hard drive and memory as insane.

Do you have product key of Windows 7 or 8 ?

Please do not post it just tell me on what is the product version - Home,Professional, etc.
 
Do you want to do it for a test the Windows 8 pro have 30 days trial I can provide you with ISO file and later on check for cheap activation key.

Unfortunately that it`a all can offer at the moment

But worth to be tested
 
so it's the OS ? how can i be 100% sure it's not an hardware issue ?
better, how can i see what cause it ?
 
i see. i suppose there are no chance for a fix then.
i have to be honest, i'll think about it. reinstalling everything again is.. a bit boring :)
 
Well I know :)

But if your pc work under Windows 8 you can use it until they come up with fix for your problems.

I think will be soon many people complain they should fix that.
 
update

i replaced windows nvidia drivers with lastest one form nvidia.

here's the log and screenshots :

even though latencymon says it's ok now, i still had random micro stutter.
 
Hi again all

This is one tricky issue, isn't it!

Calcifer ... your last graphs look good for latency, except for the bottom graph - the hard page faults section.

If we are lucky, you are one of the users for which the 364 Nvidia drivers aren't causing high latency. That's good. It might be that you can tweak a few things to get the high hard page fault counts down.

Here's a how-to from the folks who created Latency Monitor (I'm glad they released the 6.50 version, compatible with Windows 10) -- and what they have to say about investigating audio troubles caused by high page fault issues:
_________________________

Hard pagefaults: how to proceed the investigation

We believe that hard pagefaults are the most common cause of audio dropouts. The effect of a program hitting hard pagefaults while playing audio is usually dramatic. One problem with pagefaults is that they often come in groups so that a row of pagefault causes interruption of the audio stream. Another problem with them is that unlike ISRs and DPCs, putting in more processors into a system will not help you to avoid them. Page faults need to get resolved immediately and any thread that hits them is suspended until the pagefault is resolved. Hitting a hard pagefault on a page file or memory mapped file that is backed on a drive that is spun down because of a power feature may interrupt a program for several seconds until it can proceed.

If hard pagefaults are reported but no high DPC and ISR execution times you should investigate if these are the cause of audio dropouts. The difficulty with pagefaults is that they are common to occur so it's hard to find out if they are the cause of audio dropouts and stutter. In order to find out if pagefaults are the cultprit you need to know that the pagefault occured in the process responsible for producing audio and also while it was producing audio.

To verify that the hard pagefault occured in your audio program, take the following steps:

1) Stop the monitor by clicking the stop button
2) Click the Processes tab
3) Now click on the Number of pagefaults column so the view gets sorted
4) Now look for the process name of the audio application that was running and see if it was hit

Hard pagefaults should only be considered a problem if you can hear they are actually interrupting the audio stream. It is common for any program which uses a lot of memory to hit hard pagefaults. By observing the Processes view while audio is playing you can find out if hard pagefaults are being hit while audio is playing. If you found out that pagefaults are the cause of audio dropouts you should read the next section on how to avoid them.


How to avoid hard pagefaults

If you have concluded that hard pagefaults are the cause of audio dropouts, you can do any of the following to resolve the problems:

1) Close down unnecessary applications which consume a lot of RAM
2) Close down unnecessary service applications which consume a lot of RAM (the Search Indexer service is notorious)
3) Increase the amount of RAM in your system
4) Increase the working set of the audio application, only an option if you are the author of the software.
5) Make sure audio data is paged-in (resident). Pages of memory are swapped out based on their use counts. If you use Windows for live playing, do a silent run of your software synthesizer. After changing patch on a sampler, touch all keys so that all memory it uses is paged-in to avoid embarrasing scenes.
6) Disable the pagefile altogether. You can disable the pagefile by right-clicking My Computer and selecting Advanced System Settings->Advanced->Performance Settings->Advanced->Virtual memory->Change. Note that if you have no pagefile, the system can run out of memory if not enough memory is available. Also the system will no longer create crash dump files in case of a system crash.
Click to expand...

I have to admit I'm not a big believer in their last idea - disabling the pagefile altogether. I prefer to have a pagefile with a large range set manually, but I haven't really testing things much with no pagefile at all. I would expect that you'd need a large amount of system memory to completely do without a pagefile.

By the way, when the instructions above say "Stop the monitor" - I believe they are referring to their program Latency Monitor.

It sure would be nice if you are close to a resolution of the problem, and don't have to fuss with the system much longer.


[& Hi again, Andy! don't we wish everyone had ATI cards :) ]
 
P.S. ..... Calcifer, see if your version/build of Windows is current now. Start > All Apps > Windows System > Run .... and in the run box, type winver
A little box will appear with the information. The latest is Version 1511 Build 10586.164
Windows10Version.png

.... if you see an older version ... see if you can visit Windows Updates a few times to get up to date.
 
hi again !
fist of all , thank you again for helping me.

i checked windows version and it's 1511 version , build 10586.164

i launched latencymon before dinner and here's the report and screenshots :

latency mon 1.3.png

i did 2 screenshots of processes tab sorting 1st hard pagefault and 2nd PID

latency mon 2.3.1.jpg

latency mon 2.3.2.jpg


latency mon 3.3.jpg


latency mon 3.4.png

now i'm really confused because this happened when the computer was idle.
also cmudaxp.sys as second higher is incredible since i wasn't running any audio, i was having dinner and not using at all the computer.

i already installed media player classic, i use it as main video player

by the way, this is my 1st nvidia card ahahahah . i've always been an ati customer.
