How to diagnose stuttering origin with Special_K injector telemetry?

General
1

Hello! Been a fan of SpecialK since FF XV injector that fixed many issues and raised performance…since then it grew tremendously and now it gives all those telemetry options.

I have terrible issue of microstuttering in most games: Witcher 2 and 3, Far Cry 5, Control, Deus Ex manking Divided, Just Cause 3, Batman Arkham Knight on FPS higher than 36 (lol)…it gets higher than this I get stuttering (I will provide videos if you want)

Some old games run pretty well at locked 60 FPS - basically any game that loads a part of the level and it`s done.

For the last month I decided “screw it” I need to know the reason and so my journey though the internet begun:
nomerous tweaks, HDD health checks, cleaning, installing, uninstalling windows 7, 8, 8.1, 10. No matter what I do - micro stuttering.

SO maybe SpecialK injector will provide data so at least I can know the reason. I am not that rich to just toss around hardware, so first I need to know the reason.

What should I look for in widjets and how to dump data if anyone will decide to help me.

I am really desperate at this point…like breakin my head against my PC desperate.

Ok the specs:
4770k OC to 4.5 Ghz at 1.28v (OC or not OC stutter is still there) temps are not higher than 75C during gaming, AIDA stress test: 85-92C. AIR COOLING
16 Gb DDR3 RAM (yeah I am poor) 1866Mhz Kingston HyperX with 9-10-11-27 44 2T 1.5v - XMP profile / I run it at 2200 Mhz at 1.632v with 11-12-13 33 2T clocks stable (hour stability test and well actually using windows 10)
GTX 1080 TI Auros with latest Nvidia Drivers running at out of the bow clocks/ Temp is not higher than 65c on air (tried many of them every one was the same performance for me)
HDD/SSD:
Toshiba 2TB drive
Samsung EVO 850 - 550Gb
Freesync Premium Monitor GL850.

To see the problem look at frametime and frametime graph, Framerate locked at 60FPS with RTSS:

In the end I just want to know what causing it…cause I dont think Ill be able to eliminate it or minimize it at least =(

I think you’ve answered the question for yourself? I’d be surprised if the 4770k is strong enough for a locked 60fps in all of these games (at least at higher settings).

Special K can help with consistency, but i’m not sure how the 4770k will fair. Still, try out SK’s frame rate limiter.

Look at those frametime graphs. Same CPU even on stock is not skiping frames. So that’s why I asked how can I be sure it’s not faulty GPU for example?

/watch?v=U4_ZW9Wr6DI&t=246s&ab_channel=ClevoGame

Some games that load my GPU and CPU even up to 99% remain stable without frame drops like Shadow of the Tomb Rider.

5

Throw LatencyMon at the system and see if a driver spikes in latency ever other second or so.

6

That’s weird, 50-75% improvement in many areas from a 300mhz core overclock?

Test V-sync off as done in that video. If the frame-time graph is smooth, then you know it’s an issue with the frame limiter you’re using.

7

At idling or under load?

8

well he OCed it from 3.9 to 4.6 and I`m using freesync.

9

Both…

The CPU clock is indicated at the bottom (and remains consistently the clock speed as far as i’ve viewed)

hm…yeah I thought he OCed it much higher.

ok, so idling report:

Well, that sadly didn’t really tell much.

Do you use a PS/2 mouse or keyboard? I haven’t seen that driver in a while, but as I understand it it’s used for PS/2 communication.

On another note, if you’re using a USB mouse, what is the polling rate of that mouse set to? Having 500 Mz or 1000 Mz can cause microstuttering in some games.

15

@EL_Tigre1 i’ve edited your posts to make the logs collapsible.

16

And make sure you’re not forcing anything through the NVCP - leave everything to global settings. Disable freesync as well, and test these games with v-sync off.

17

already done that while DDUing drivers one after another.

18

yep I`m using an old PS/2 keyboard, as for mouse, I even pluged them both off to test. Same. I tried sooooo many solutions from the web, that at this point I tried them all (apart from building a new rig). I thought maybe someone will help me to diagnose the problem, like checking the event logs and looking for errors and looking for a certain error that can cause stittering in games.

19

You’ve done this too? You can also try SK’s frame limiter and see how that fares instead of RTSS.

20

tried it too…it smooths locked framerate much better but doesn’t help with microstutters. Maybe there are some soft to check CPU, GPU for errors like memtest for RAM.

21

Have you tried running any game off your SSD?
