Norwood is a portable app that enables on-screen viewing of CPU usage displayed from a sizable line-graph.
It is designed to be direct and to the point, providing you with a live view of your machine's CPU usage. It includes several options like update rate, line width, transparency of the graph, and whether or not to allow graph click-through. You can also choose the various color attributes for your graph.
Norwood is nicely presented and simple to use for any skill level user looking to keep an at-a-glance handle of their machine's CPU usage in real-time.
