Microstutter Issue + Airflow Tips

[Dragoon_]

Hello friendly members of the LTT community,

 

Let me start of by saying I am young (16), however have a fairly good understanding of computers/ terminology. however please don't go using massively complicated terms without an explanation as I don't have a degree in IT. With that in mind I play a lot of videogames, and over two years I saved up money from holiday jobs to build my OWN PC . Needless to say when i got it working I was incredibly happy, however after having the computer for a year I have started noticing a small constant stuttering that is really...really...annoying. It's very small, however constant, despite having a high framerate it seems like every frame stutters slightly. I have tried re-installing windows, formatting my SSD and HDD, re-installing drivers, running with one stick of ram, running with different ram slots, running a lower overclock on CPU and RAM, it's not a thermal issue, while my CPU runs at 84*c max on load (I run my I5 3570k at 4.7 ghz on a hyper212 evo...yes it runs stable i left it running for 2 days with aida 64 stress test running and the peak temperature was 84*c. Anyway, my only thought is a PSU Issue however I'm not exactly rich, so buying a new PSU is out of the question for now.

 

[Edit] Yes the rear 120mm fan is blu tacked (sticky tacked) to the rear 90mm fan hole. My front fan broke and I ordered new ones last time I had some cash and 2 came so I just detached the rear fan and tacked this one of the rear 90mm mount... ghetto af but it works!

 

~Specs~

-I5 3570k {at 4.7ghz

-R9 270x [Asus]

-Asus P8Z77 -v -lx

-Hyper 212 Evo

-HyperX blu black RAM {at 1800 mhz}

-WD blue 1tb HDD

-Samsung 840 Pro 256gb

 

My second question is whether there is anything I can do to imrpove the airflow in my (admittadly small) ATX ase, with a non-modular PSU [see pictures]

 

Thank you for taking the time to look over my post, please tell me if you would prefer me to format the post in a different way

Update your GPU's drivers?

I must say that GPU is severely underkill with a 4.7GHz Intel Core i5

Proud of your cable management. But if anything i would say try and invest in another case. That would be your best option as you would have more areas to have fans pulling and/or pushing air out of the case thus fresher and cooler air for your CPU fan to blow through ur cooler and better temps on your CPU. So yeah thats it. I assume you have the fans at the front pulling air through the front and at the back the fan is exhausting air. So take that configuration and put it in a nice case with many options like a corsair 450D which is really nice. Linus did i video on it so check it out and see what you think!!

Thank you! The 450D is £100 ($147) where i'm from, for that money I could buy an Define R5!

Best i can afford my friend, I think I won the silicon lottery though (i've tried running beta 15.4 as well as Omega 14.12)

@Dragoon_

You've piqued my interest. Did some researching on microstutter outside of crossfire/sli setups and I have found that most people solved it through changing options in Catalyst Control Centre. Specifically options pertaining to frame limiters and refresh rates.

For example your monitor operates at 60Hz but CCC is limiting your maximum frame output to 58fps that will cause microstutters. Did around your settings and see if some options were enabled by default that shouldnt be. Worth a shot.

I'll keep digging.

Interesting, i'll have a dig around CCC myself and see what could be causing problems, thanks for the tipoff!

 

[edit #2] My frames in game seem good, usually in the regions of 75 - 100 in BF4 and 200/300+ in games like CS:GO and DotA2, i'll keep on digging!

 

[edit #3] Should i have mentioned I'm running an Flatron IPS234 monitor from LG @ 75 hertz, clocking it down to 60 just makes the stuttering worse/ make things seem, I know it's a really unspecific word but "laggy".

Progress:

 

I have pretty much looked up and down catalyst control centre everything seemed normal (no limiters or lower refresh rates coming from the GPU that I could see) However I have come across these settings (see picture) I havn't touched them yet can anyone tell me whether these could be my problem? I'm using a modern monitor on a fairly short cable so shouldn't I leave them as is?
