Works very well with Hurricane/AutoCAD, especially if you are a power user who is maxing out every last ounce of processing power from your PC, and also want to do other things while your script is grinding it out.
Process Lasso will effectively allow you to have a batch running in the background, while effectively working in the foreground without any sense of what else your PC is doing.
This is probably the only software of it's kind, as the rest of these "optimizers" that I've tried did nothing bust "mask" over things.
