Problem(s): My processor will not idle at 0%. This creates lag (Specifically in DirectX applications).
(I am running a clean install, and there aren't any programs running in the background)
The only thing that seems to quell my Processor's behavior is to uninstall the NVIDIA driver and run on the generic Windows drivers.
My CPU graph:
As can be seen in the screenshot, when the computer should be idle or at 0%, the "System" process jumps from 0% to 30% every second or so. This causes lag in Programs and in and Direct X applications drawn to the screen.
Using xperf to track the traces running in "System", I found that nvlddmkm.sys is the driver responsible for the CPU usage:
The cause for this irregularity seems to be unknown, I have been unable to find anything else like it online, except for a blog where someone posted about how an incompatible Modem driver was causing a similar problem in his computer:
Upon reading the blog, I found something that may apply to my current situation. Quote:
"The developer explained that my trace revealed that the driver didn’t efficiently interact with the PCIe bus when processing specific queries"
Whether or not this is the problem is still a question.
