The software works pretty well, the UI could be improved, but I was able to see all my CPU information live which included temps which was nice, Windows could learn a few things.
The addition of the RAM test is very cool and suprisingly doesnt take too long, it managed to full all 32gbs of my memory pretty quickly and didnt find any write and read errors :)
The GPU control with the Screen Refresh rate tester isnt bad, I think it could be layed out better.
The processes control is basically the details tab in windows task manager
The Sensors control is very helpful, it gives me all the sensor and usage information for all my PC hardware components all live.
The ability to create your own widgets and overlays from the list of hardware sensors and stats is great, super helpful when you gaming and you want your hardware usage and info in realtime. The Frames per second widget, took me a few minutes to figure out but it basically counts how many frames per second you are getting but it works only when there is stuff happening on your screen.
