Thanks for posting that as it speaks volumes to your problem.
I believe your DPC latency test concludes that you have some rather serious 'DPC Latency' issues with your computer which implements a significant amount of unnecessary input lag, stutter, sluggish movement, etc. At this point, DPC Latency Checker should be your best friend so you can tweak your system and check to see if your DPC Latency has improved.
Your DPC latency ranges from 42-751us, which is absolutely horrible. I wouldn't be surprised if you also have a lot of 'cracking & popping' w/ your audio. My DPC Latency ranges from 2us-15us. Your test illustrates that you're spiking in the upwards of 700us at consistent intervals. This can be caused by many things... Off the top of my head, try the below tweaks, and after each tweak, re-check your DPC Latency.
1) Open up your services.msc app. Click the start button and type services, open it up. Check the link I gave you and find out what services you should disable as many window's services cause significant DPC Latency spikes. For starters, find 'Window's Event Log' and disable it. There are several other services that can cause this.
2) This suggestion may be even more likely to be causing your latency issue. You may have a faulty driver causing these spikes... this is very common and something I've dealt w/ quite a bit myself.
Open up your device manager (right click my computer then click properties) and disable your devices one-by-one. Check your DPC Latency each time you disable a device (network card, audio device, rom drive (dvd, blu-ray, etc), wireless device. If you discover that your DPC Latency has ceased all spikes and has lowered significantly, you have found the culprit to your problem. Uninstall the driver and roll back to the previous one or newest release. If you're already on the driver's newest release, roll it back.
Also, make sure to properly update your motherboard's intel/amd chipset drivers to the most current. Lastly, go to your motherboard's manufacturer website and download the most current BIOS version and update. Your BIOS version can also be causing these spikes.
It's a pain in the a$$ troubleshooting process, but it's necessary to resolve your problem. I know I said this before, but make sure all your C-power saving settings are disabled, HPET, cool n quiet, hyper-threading... check the guide I gave you.
Start testing and report back.
Cat, as you know, overclocking is a science, and depending on how you have overclocked your machine, these c-state power settings may affect your overclock, but it will likely affect your overclock in a positive manner. These settings restrict power to your system/cpu, and many overclockers disable all c-state settings to maximize their overclock, but it's situational depending on your setup.
Personally, I'd suggest disabling all your c-state settings, checking your DPC Latency before and after, then running a stress test on your CPU with your c-state settings disabled. Many will run a stress test over 24/hrs, but doing it for at least 2-3/hrs is necessary. If you're unsure how to run a stress test for overclocking, google it. Many great guides out there, and I'm hoping you have an aftermarket cpu cooler or I wouldn't be overclocking.
I overclocked my CPU when I got my computer. It's at 4.3GHz and it maxes out at about 67 or 68 degrees C with Prime95 running for an hour.
hehe, I've been searching YEARS for the reasonTell me when you've found it. Until then I'll accept the fact that I suddenly unlearn some skills (like railing) under certain preconditions

If you're maxing out at 67-68/deg, then you're solid.
Trying disabling your c-state power settings (all of them) in your BIOS, and check your DPC latency 'BEFORE & AFTER.' If your DPC Latency has much improved (it should), download a stress test program for oc'ing and stress your system for as long as you can. See if it has any impact on your peak cpu temperature. If it's negligible, disable those suckers. IMO, this is a MUST for gamers. Those settings implement a good deal of input lag because your system is restricted of a consistent max power throughput.
I've isolated DPC Latency spikes caused by the Intel(R) 82579V Gigabit Network driver. Problem is there are no later versions of it that I can get that fixes it and I kinda need it to have an internet connection.
Problem persists with Microsoft Security Essentials' RTP disabled, so that's not it.
EDIT: Further testing and googling reveals that the problem is with Malwarebytes' malicious website blocking... Disabled that. Now the highest spikes are at 400us every minute or so. 50us average when using my soundcard, 10us when no sound is playing.

I'm back. After some tests I found the culprit to be Realtek Ethernet adapter driver. I manually downloaded the newest version from their site, result is this:

Didn't test it in-game yet, but many thanks for help you provided, c3.![]()
I ran the dpc test normal and under load... load being... fl studio with a bunch of plugins running.... ql in windowed mode and a movie playing in media player classic. Normal things run tween 5-10 us and under load 15-25. Still experiencing the same problems in game. Have tweaked my system, graphics drivers ect ect ect. I've never had fps issues... steady 125 on all maps. There doesn't seem to be anything to do about it.I don't have any of these problems in other games.
