In depth
A closer look at CPU100%!
The suggestive name of CPU 100%! reveals its purpose to you from the start. It is designed to simulate a situation when your CPU's usage rises up to 100%, enabling you to evaluate its performance during uninterrupted full load. Since its only function is to increase the CPU usage to maximum, the application does not bundle any other options and features. In fact, its main window only contains a notification message that alerts you that your CPU peeks at 100%, without any menus, buttons and other elements whatsoever. When you launch it, the CPU usage does not jump to 100% instantly. A reliable monitoring tool can help you keep an eye on the current processor load, which first goes up to about 90% and then rises until it reaches the upper limit. On other computers we tested it on, the CPU usage did not exceed 70%.
