DPC Latency Checker

[Ao1]

Intriguing. I don't know if your latency is just insanely low or if mine is retardedly high, but I'm on a mission now to get mine down.

AFAIK DPC latency has nothing to do with the speed of the pc it is to do with latency between the cpu and the rest of the system at driver level.

If I run in safe mode my system is a lot more snappy so there must be a driver or back ground service slowing things down somewhere. The difference between safe mode and normal mode is like the difference between ssd and hdd.

EDIT:

Abbreviated from here: http://www.raymond.cc/forum/tutorial...y-checker.html

DPC Latency Checker measures the response time of your system. The response time is influenced by any other application that is currently running on your system. For an accurate result, we recommend you to close all applications before launching DPC Latency Checker. If you run this tool while there are applications open you will notice that, while you close them, the results will improve.

Device drivers are high-priority tasks that need to be processed right away before any other task. If a device has an improper driver this operation is going to take more time than usual and it's going to slow down the system.

The length of delay varies greatly between computers and the software and device drivers installed on them. DPC Latency Checker is a tool for checking how bad the latency of a computer is, and can then be used for troubleshooting.

The checker can be left running while changes are made to the computer to see if they improve the situation

Unfortunately DPC Latency Checker only shows if there is a device driver problem, not which driver is causing the problem. You will have to manually disable and then re-enable each device driver from Device Manager.

EDIT:

@One _Hertz, was your pc switched on when you ran that check

Disabling drivers one at a time could not find my problem. Maybe it's a back ground service or maybe it's just an accumulation of lots of things.
