The System Idle Process shows the free processor time on your PC. So, if a process runs for 2 hours while using 50% CPU, its CPU time shows 1 hr. And the CPU time shows the total processor time a process has been using since its launch.ĬPU time of a process = Process uptime * CPU utilization of the process.

The CPU column shows the CPU usage across all cores for individual processes. Then, make sure to tick CPU and CPU time.

First, right-click on a column name and pick Select columns.

You can go to the Details tab to get more information on CPU utilization.

If the CPU column is absent, right-click on any column name and tick CPU.

It also displays the total CPU usage above the column name.

Click on CPU to sort the list in ascending or descending order based on the CPU usage.

You can see each app’s current CPU usage on the CPU column.

The easiest method is to press the Ctrl + Shift + Escape hotkey. There are many ways to open the Task Manager. It provides somewhat brief information on this data, which is sufficient for most users. The Task Manager is the most common program to check CPU usage. But you can also use command-line interfaces such as PowerShell. Still, if you’ve reached this point with no solution in sight, you won’t lose anything trying a different one.Most users often use GUI tools such as Task Manager or Resource Monitor to check CPU usage on Windows OS. It’s rare for the Linux kernel to be the reason for high CPU utilization. Still, those don’t share the exact feature set and may lack some functionality. Alternatively, you can try open-source versions of your GPU’s drivers. The solution is upgrading or downgrading to a different version. Xorg doesn’t really get along with specific versions of Nvidia’s or AMD’s drivers. Sometimes the GPU’s drivers can cause high CPU usage, too. Sometimes, by enabling compositing support, you’re also enabling many demanding effects. Although officially the compositor offloads CPU-related tasks to the GPU, that’s not always the case. Save the file, reboot, and hopefully, everything will work okay now.įor Xorg, try disabling your Window Manager’s compositor.
