Frametimes are insane, and I've done everything to fix them.

My frame times are all over the place and there is seemingly no reason or nothing I can do about it. They do not correlate to my frame rate, nor do they make ANY sense.

I began having stutter/hitch issues in everything a few months ago. I did an insane amount of troubleshooting before throwing in the towel and buying all new hardware. The stuttering is worse in Open world titles and also with video.

My frame times are terrible in everything as seen here. This is taken from a few minutes in scum, but it's the same story in every title, minus less demanding ones like Rainbow Six.

Gpu temp and power is fine: https://imgur.com/a/MskEv8N

Core clocks are stable: https://imgur.com/a/r0FXsXj

Cpu temps are fine: https://imgur.com/a/7rC4G7m

Yet I still have terrible frame times. I have replaced all of my hardware except the Motherboard and Psu (which was changed earlier this year). I did try a new Mobo, but with my older components, to no avail so I reverted back to my old one. I put the new CPu, and Gpu and Ram in the old one again (having ruled it out as a problem), so maybe it is killing something crucial off?

None of the Hardware shows any sign of problem that I can tell while monitoring, such as High temps, voltage issues, clock dips etc. The issue is widespread and affects all title and videos.

I have done 100+ hours of troubleshooting

So far I have.

  1. Changed all of my PC components (to an i7) Psu, RAM, SSD, Cables, 4 different Gpu's including two 1070's. Tried a different MOBO, but it didnt change so placed new components into my old mobo.
    1. Tried every different combination of windows settings, optimisation I can think of.
    2. Tried multiple different fresh windows versions on different drives.
    3. Installed only basic software.
    4. Changed Bios settings and profiles, tuned of iGPU
    5. Looked at temps, voltages and profiles.
    6. Tried about 10 different Nvidia drivers
    7. Lowered graphical options and other settings like Sync
    8. Ran many tests like userbenchmark, furmark, prime95, passmark uni engine (which stutters too)
    My frame time graphs are always all over the place, even with a locked fps, that doesn't drop, the frame time will shoot up to 200-500 all of the time.
It's a complete mystery, it's been over 6 months of wasted time so far, I'm about to completely give up.

Specs;

I7 4790
Gtx 1070 Strix
16gb 1600Mhz
Samsung Evo 960
Evga g2 650w

How would a Psu cause stuttering, I have ordered one for delivery tomorrow for testing will get back to you.

Intermittent power/latency on the 12v rail that is supplying the graphics card/CPU can cause the issue. Have you monitored the 12v rail to see if you have a consistent supply voltage when under load?

So i like the idea of the PSU as its the only thing not changed....'Sherlock Holmes' "Whatever remains however improbable must be the answer...."

But humour me for a minute, having issues with your audio drivers?

Did you received your PSU and have you teased it to see if the issue was resolved? When i read the description i assumed that the PSU would be at fault.

I have a similar spec and small stuttering with fps generally high in games.
Interested to see what works for you before I put 100+ hours into testing
