I need ideas.

Help... I have gotten a computer with an Fx6300 overclocked to 4.00 Ghz, 8 GB ram and a gtx 750 ti. It had playable fps but horrible studdering. I googled it, and found some ideas.

 

one of the most common solutions is the two cmd commands that seemed to fix it for most people but not me. So I said maybe it is a problem with my cpu so I upgraded everything until it looked like this 

gtx 1070

i5 6600k oced to 4.1 ghz

12 gb ram 2133

and eventually a new hard drive where I installed Windows again. 

With this new gpu I get insane fps but still studdering. All drivers are up to date including mb bios on my Msi z170 sli plus. On idle I get a 50% disk usage, could that be it? I haven't really installed any cpu drivers though but I don't think that is the problem 

 

thanks in advance

-Jon

What exactly does this test

DPC latency.

 

DPC is deferred procedure call. The latency aspect is the deferring part. DPC latency occurs when high priority tasks require immediate action, so they postpone lower priority tasks in favor of the higher priority tasks. The reason we measure this is because it allows us to pinpoint severe issues within our OS environment such as driver corruptions, component malfunctions, or program faults based on the amount of processing time they take up.

 

This could correlate to your issue. Typically, when DPC latency spikes occur, it causes visual and auditory stuttering, and it can be exacerbated under load. These spikes will affect playback irregardless of how adequate your hardware is. Typically they're hard to diagnose without software meant specifically to track it as DPC won't show up in any other hardware monitoring programs, or in Task Manager.

 

It is possible to track DPC latency within Windows using Performance Monitor, but this is a bit easier to use for people who aren't very familiar with using the Performance Monitor utility.

i think i will check with performance monitor.

i would rather avoid installing new software. expect screenshots soon, thanks for the support

yeah i decided to use DPC latency checker.

not pretty. any ideas on lowering it?
