Prism HUD is a program made by Util's Heaven. The objective of the program is to have a display of your computer's CPU and resource usage. Its HUD (Heads Up Display) allows the program to show you all the information you need to know about your computer, but without too much distraction or obstruction. With very soft and transparent colors, the HUD can be located anywhere on the screen (top right by default), and it is always present (though this can be configured).
The program can show you the total CPU usage, the total Memory Usage, the Disk space available, the network transfer rates, and the CPU and memory usage of each process. You can customize each bar and select what you want it to measure and what colors to display. The bars appear in a very stylish layout, which make them noticeable but not annoying. Perhaps Prism HUD is not for everyone, as standard users do not feel the need of monitoring their computer's loads and processes all the time; but for those who do need this kind of information, Prism HUD is an excellent option. Although it lacks the level of control provided by a task manager, it is stylish, customizable, and also free.
