When I upgraded to Win8, there was a lot of lot of fuss about the DPC latency program and hos the Win8 kernel something did not work together With DPC latency.
now, there was a program which I installed that reduced the reported DPC latency to about half. But I dont remember the name of it (I just did a clean install)
 
Anyone know?

Yes, but no
 
Your link is for latency monitoring, I'm looking for a program that just by loading reduces the reported latency.

In app that reduces latency by half just by installing? That has to be a con surely?

Linux maybe?

So far as I know, there is no app that can change any driver you have installed automatically. I wouldn't want such a thing anyway. The app I linked to identifies issues so you can fix them.

Upgrade your processor and ram.... Get a cheap ur22 and for 450$ u will have no latency.... Microcenter 8core chip for 100$ & a free motherboard and 16 gigs ram for 100$ and a decent low end professional soundcard like the ur22 for 150$, & I promise.... I can't barely put enough effects and vsts to make a touch of latency. I know the math doesn't add up.... But there are always extras like gas and bus fare. Haha. . The soundcard is always one of the greatest reducers of latency... Besides sometimes having two hard drives.

There is no program that can reduce DPC latency across the board, because there is no single cause for it. The only cure I know of is well-written drivers and fast CPUs. That and turning off processes that incur high overhead and aren't needed for the task at hand.

Hardware sets the floor for latency, below which you cannot go. But even very good hardware can host serious problems in software (drivers, resource hogging processes etc.) that will make audio work difficult. DPC latency issues are among those problems, and you really can't just buy yourself out of those. Often new hardware looks like it solved a problem because the operating environment is changed during the "upgrade."

Hmm. Did you read the OPs gear specs in the signature? There's no way the latency he's experiencing is caused by
lack of hardware resources.

Latency has many causes. The only way I can get rid of my "spikes" is by going into the Device Manager and disabling the Network Driver when I want to do any serious work where I don"t have static/crackling every 2 or 3 seconds. Uppiong the buffers has no effect at all. (FWIW, Bluetooth and WiFi drivers are already dead and buried and nVidia Sound Device is also disabled.)
