what is this: "SolidWorks Resource Monitor"? !
It's just a process that runs in background and informs you if you are exceeding your computer capabilities. RAM and Graphic card resources to be exact. So if suddenly averything starts lagging you will know where is the problem.
If it turns yellow, be aware that system has almost no free resources left and might crash, so save your work and close some youtube videos!
