Process explorer windows 1011/7/2023 ![]() ![]() ![]() Because the Rift, a virtual reality headset, requires low latency, their software seems to set the IDLEDISABLE power configuration to "1". Process Explorer is only showing 1-2% CPU usageīefore I go uninstalling everything, how would I figure out what's causing the issue if nothing weird is showing up in Task Manager or Process Explorer?Īfter much debugging, I was able to come to the conclusion that my specific case was related to a bug in the Oculus Rift software.CPU is not throttling down automatically based on the dynamic load, causing high temperatures and the fan to kick in.No individual process is taking up significant resources in the resource monitor list.Task manager and resource monitor graphs shows 100% usage total.This same issue also occurs in Safe Mode, so I'm guessing that it's more along the lines of something to do with Windows itself. I've already run both Windows Defender and Malware Bytes (a virus was my first guess), but nothing has turned up yet. Again, nothing looks out of the ordinary in the process list, but the processes are showing the levels of activity I would expect in Process Explorer. The really weird thing is that Process Explorer shows only 1-2% usage when idle, with the System Idle Process taking up the remaining ~98% as I would expect. Everything seems to be "using" a significantly higher amount of CPU resources than it normally does.Īs an attempt to diagnose the problem, I've also tried using Process Explorer. None of the processes are abnormal, and though the process CPU percentages do add up to 100%, it doesn't make sense to me that each individual process is taking up as much CPU as Task Manager says it is. The weird thing is, when I look at the process list, there isn't really anything obvious that's triggering it. If I go into the Windows power settings screen and manually change the processor power maximum to 50%, then it's capped at 50% frequency (~1.5 GHz), but it never goes below the maximum possible frequency. Because of this, it's constantly running at 3.3 GHz and the temperatures are rising to the point where the fans kick in at full force. Out of scope: CPU parking - see this link to DISABLE that.Ĭonfiguration export: ProcmonConfiguration.Starting yesterday, I have a very odd problem on my Windows 10 desktop- my CPU is constantly running at 100% (according to Task Manager), and it isn't throttling down. In my 8-logical cores machines this grows 8s for every 1 second of real time this will be the accumulated user time.Double click process to see a detailed timeline.Run a CPU-heavy for some seconds for testing purposes:.if you are getting more, check the filtering again.very important: confirm that you are getting about ~300 events per second.ENABLE the last type of event (very last icon on tab bar - see picture). ![]() DISABLE all events on the very right side of the toolbar (ie, 4x icons) all type of events (4x icons on very right side of tab bar).start it (1st time), then use the following shortcuts in sequence:.Step by Step instructions, based on the answer of "Der Hochstapler" So, none of these are quite what I need: I need to get a file that contains something like 'top 10 processes by CPU, every 15 seconds, until I stop the monitoring' The reason I need this because I have a machine on which some process is causing occasional brief spikes in CPU usage several times a day and I need to find out which process is the culprit.Ĭan anything do that, or have I missed some feature of perfmon or process explorer? Save the file as a snapshot of a single point in time Process Explorer will let me break down by process, but it will only.Which is almost what I want, except that as far as I can see it Time-based file (taking snapshots at specified time intervals). Perfmon will let me save to a file, and will additionally create a.Task manager shows me the %CPU per process but only visually - no.Is there any easy way on Windows to log %CPU time per process over time to a file for later analysis? ![]()
