Question Microstutters on good PC

[karolos bizos]

So I buit this PC a few months ago thinking i'd finally escape these same microstuttering issues I had on my old build but no luck so far. I basically have the average fps you'd expect in every single game, which get ruined by the 1% and 0.1% lows. The issue appears mostly in open world games like The Witcher 3, Red Dead Redemption 2 and Days Gone where a lot of new things have to constantly get rendered. It absolutely is the worst in Red dead redemption 2 in saint denis (big city). Average fps of around 90 with drops to 35 every 10-ish seconds which are very apparent. I have spent countless hours trying to fix this game both before and after upgrading, nothing worked. Lowering settings does help but I can't accept that as a solution when I play at 1080p, basically scamming myself. Background apps are definitely not the issue as I close most before testing and task manager doesn't show anything using excessive resources. Hardware wise I have heard bad things about my M.2 SSDs (both the same model, one of which has windows on it), if not that maybe some weird incompatibility between RAM and motherboard or motherboard and SSDs. Anyway, any help is greatly appreciated as I this has gotten irritating and I have trouble enjoying games.

Specs:

GPU: 4070 Super, CPU: Ryzen 5 7600, CPU Cooler: Arctic Freezer 34 Esports Duo, Motherboard: MSI PRO B650M-P, RAM: 2x8gb at 5600Mhz Kingston KF556C40-8, Storage: 2x 1TB Kingston SNV2S1000G

same microstuttering issues I had on my old build

if the disk is carried over from a different build and still experiencing the same issue it's likely that the data just cannot be processed smoothly.

try a new disk with a fresh game install to verify for sure.

I built this PC a few months ago

make sure you are on a fresh OS installation for the new motherboard.

and make sure you are on the latest BIOS available for this board.

Specs:

include the PSU make & model + it's overall age.

Both the drives are 1 month old with a fresh install of windows and everything, I have updated the BIOS to the latest version, PSU: Corsair CX750 and also 1 month old. None of the parts are carried over cause I gave the old computer to my dad

PSU: Corsair CX750

the CX series are low quality units.
i really wouldn't be surprised if it has issue offering proper power for usage like gaming.

the fact that lowering graphical settings improves the situation noticeably would lend to this theory.
since less GPU strain would allow better performance through the unit when not spiking wattage.

if trying a new disk for games still didn't allow expected performance i would consider the PSU as the next step in troubleshooting.
though i would probably replace this thing anyway to avoid any possible issue in the future.

That's a helpful lead, it is a bronze rated psu i suppose but i thought 750W would be plenty. Would you recommend to test this theory through maybe like a system-wide stress test to confirm it? Cause I don't want to spend money for a better psu just to see no improvement in stuttering

 

[geofelt]

Stuttering is caused by a temporary loss of a critical resource. Usually cpu, but occasionally by shortage of ram.

Unless a critical ssd is over 90% full, ssd performance should not be an issue.

Some games today need more than 16gb.
Look at task manager/resource monitor/memory tab and the hard fault column.
If you see any hard fault rates above zero, you can use more ram.

Every 10 seconds is suspicious.
I might suspect something like Nvidia experience checking for updates.
Try uninstalling it.
Perhaps an email doing a send/receive every 10 seconds.
Do you use discord? if so try stopping it.

Your cpu cooler is not the strongest. Could you be throttling?
Run hwmonitor or such and look for temperatures of 95c. or so.

this energy efficiency rating doesn't correspond to the quality of the manufacturing or the technology used within.
there are many gold and above rated units that are even dangerous to use.

and the max wattage may be enough, most RTX 4070 S require ~650w minimum, but it's the unit's ability to deliver that power in a steady stable stream that is necessary.
lower quality units many times just cannot provide that.

Would you recommend to test this theory through maybe like a system-wide stress test to confirm it?

i would, but while under different stressful environments would keep an eye on all live aspects of the system;
RAM usage,
CPU usage,
GPU usage,
disk usage, etc...
