NZXT has today launched a new update to its CAM software made for PC monitoring. The latest 4.0 version bring many features to CAM with better application performance and UI design. The software has been redesigned from the ground up with a goal of improving overall user experience, with better features like nicer overall UI to prioritize showing only the most important aspects of your PC's health. There are new sections like bandwidth and resource per-process tabs that let users see where is their PC spending its resources.

The application has also seen major "under the hood" redesign as well. It is now optimized for better performance and uses less system resources. This is also important when using CAM's built-in overlay during gaming sessions as it will leave more CPU time available for the game instead of using it up. The overlay also got some enhancements like customization of what is displayed during its use for less intrusive experience. Additionally, all peripherals that were compatible with previous versions of CAM software will continue to be supported during this 4.0 release, giving users more options to control their fans, coolers and RGB lighting setups. In addition to a bright UI, there is also a choice of dark mode to blend in with your Windows theme. NZXT CAM 4.0 software is available for free download here.
 
I'll have to take a look at this later and see if the improvements are worthwhile
