No need to run the application with "sudo" Hardware selection options (selecting CPU cores, disks, network cards, GPUs) Plotting performance data of multiple devices at the same time Interactive charts for querying performance data on any point Option for showing processes as tree or list Optimized for low CPU usage Customization menus for almost all tabs Supports ARM architecture Free and open source Notes for Limitations: GPU usage information availability depends on vendor/driver. GPU load is not tracked if GPU tab is switched off (for lower CPU usage). Virtual machines may not provide CPU min-max frequencies, sensors and RAM hardware information. Non-Flatpak versions of the application has higher performance (start speed, CPU, RAM usage). Notes for Flatpak Support: Flatpak version of the application uses some permissions (like not sandboxed) to access performance/system information of the host OS. Flatpak package of the application may be installed for system-wide instead of user-specific for avoiding source code modifications.
