GLXOSD (Graphic Library eXtended On-Screen Display) is a powerful software for monitoring multiple graphs of computer system parameters in real time. It is designed to provide a graphical representation of the system performance, including CPU and memory usage, disk activity, network utilization, power consumption and temperature. GLXOSD also provides detailed information about each monitored parameter, such as the number of cores, frequency, etc. Additionally, GLXOSD can be used to monitor the progress of specific applications, such as gaming or video editing. GLXOSD is available for Windows, Mac OS X, and Linux systems.
