Stuttering in every texture loading ! gtx 970

[jonomaia]

Hi everyone. i'm have a weird issue in my pc about quite sometime now and i don't know what to do anymore to try to fix it...

Basically all games that requires texture loading causes stuttering every time that it is loading them. in open worlds it happens the most. but even on games like Rocket League, when you open the game or change cars in the MENU, the stutters occurs. I noticed that it diminishes after playing and loading them for the first time. I my mind, it could be caused by the load from the HDD, that is the slowest part in my pc. with that in mind, I have bought a new HD, 7200rpm, that sped up considerably all other operations, but the problem still persists...

The prime examples are: PUBG, GTA, ROCKET LEAGUE, F1 2017 (just in the begining of race, when loading some txtres).

Other examples like ASSETTO CORSA, even in max settings and with 20 cars on the track, with gpu and cpu usage very high, it basically never occurs.

 

My setup:

16 Gb RAM Corsair Vengeance 1600 cl10

GX650 Cooler master CM edition PSU

Gigabyte 970a UD3P rev. 2 motherboard

FX8370E AMD 8core.

Corsair H45 water cooler

1Tb Western Digital Blue 7200 HDD

Windows 10 pro OS

 

Here’s a List of everything that I have already tried:

 

-reset/remove overclock from cpu, tried underclocking it too

 

(system is 100% stable in Prime95 and IBT AVX both defaut clocked, overclocked or underclocked)

-reinstall games
-check no to "fullscreen optimizations" in windows 10 options
-set energy options to maximum performance and set cpu to always 100%
-chkdsk - ok
-memtest - ok
-HPET on and off – in BIOS and System
-uninstalling msi afterburner and VFX audio enhancer.
-disabling superfetch, telemetry and other system stuff
-disable nvidia cache shader
-fresh installed win10. 
-underclocked and overclocked GPU and CPU. no good
-tried RAM in single and dual channel, both sticks alone, higher timmings, xmp on and off. 
-reconnected the cables and gpu. no good.
-switched PCI slots 
-tried various setting and power options of nvidia control panel and NV-inspector

-tried uninstalling the Video drivers, tried with various older drivers.

-disabling HDD caching

-tried HDD in AHCI and IDE modes

-tried all SATA ports

-unplugging my PS4 controller

-disabling OS paging file and setting it to system managed.

-updated BIOS to latest version

-converted HDD from gdp to MBR

-unplugged mouse, headset and keyboard.

-increased resolution to 4K, and decreased to Below FullHD

-tested with HDMI and VGA cable.

-reseted BIOS CMOS
-tried 2400, 2200, 2000 HT link in bios.

-overclocked GPU +50Mhz (stable 1442Mhz clock with +12.5mV overvolt, Max temperature reached 82)

-Bought New HDD.

-tried disabling windows defender, firewall etc

-disconnected net cable

-locking it to 60 and 59 fps, as well tried to change monitor refresh rate to 59. 

 

I don’t know what to do!

 

CPU temps were at least 10 degrees below the thermal throttle margin

MOBO temps are ok as well, all staying below 61 degrees

GPU mobo is setted at max 80 degrees.

(+stutters occurs even in low usage gpu moments like menus and other stuff, even when is under 50 percent memory and buffer usage. It happens too when very much below the thermal margin set, like 62, 63 degrees)

(+stutter still occurs in less than 60% usage CPU tasks)

(+CPU is overclocked to 4.3, 1.375V.)

 

The Auto overclock from Nvidia boosts it to 1390~ MHz core clock.

the manual overclock made by XtremeTuner Plus boosts it to 1442Mhz core clock and 3670Mhz memory clock.

 

There's a video with examples: https://www.youtube.com/watch?v=GYWsCvrc7V4&feature=youtu.be

Sorry for the quality, i tried to record from phone to not add another variable.

Did you try capping the fps at 60 with v-sync? My old 60hz monitor didn't like a lot of games without vsync

[jonomaia]

yes! tried it to in  XtremeTuner Plus, locking it to 60 and 59, as well tried to change monitor refresh rate to 59. 

same results...

Do you know how much VRAM you're using? You can check either in Task Manager (if you're on Windows 10 Build 1803) or GPU-z.

Does the stutter sync with the hard drive light being on?

I'm simply curious if the throughput from the HD to the CPU to process, is an issue.

Also, did I miss it somewhere or did you not list your GFX card?

[jonomaia]

about the Vram, it happens even on low usage. tried rocket league in minimum settings and with resolution down   and the results were the same. from what i remember, monitoring through HWmonitor, id didn't even hit 60%.

 

about the sync with HD, i have noticed that the games where HD* is basically idle like the quoted Assetto Corsa, are the ones that the issue do not happen.

The Gpu is in the title but i forgot to put it on text haha. Its a GALAX GTX970 4Gb OC edition.

[jonomaia]

plus: i also realized that in random games like "Enter the Gungeon" - an indie that even a cellphone could run, it occurs sporadically. 

even the system itself sometimes blinks the desktop and explorer stuff.

running some tests in latencymon, i've got two different results in the same situation.
1-some of the times I get the "you system is stable for blahblahblah..."

2-some other i get:

Your system seems to be having 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.

I've uploaded 3 screenshots of the exact moment when stuttering occurs. the biggest drops at the end are the "literal loading" after finding a match. the spikes before it are the stutter times.

Isn't it obvious? You need an SSD. They exist for a reason. Open world games constantly load from the storage, and if it's slow (HDD) you get microstuttering.

[jonomaia]

well, it is not so obvious because of 2 examples: my brother and my friend both have almost identical setup in terms of cpu and gpu: one does have a gtx970 and a FX8350 and the other an gtx970 and a FX8300. BOTH DON'T HAVE SSDs. BOTH DON'T HAVE THIS PROBLEM.
That is why i think there's something else going on...
