Process Lasso Pro

Process Lasso Boxshot

Process Lasso is NOT yet another task manager. It is a system automation and optimization utility containing a fleet of algorithms to dynamically boost the performance of your PC and retain responsiveness during high loads. Among them is our famous ProBalance algorithm that temporarily reduces the priority of troublesome background processes in order to improve PC responsiveness, as shown in real-world and synthetic tests. Then there is the Bitsum Highest Performance power plan, tuned to give you maximum performance when you need it. IdleSaver will drop you down to a more conservative power plan when you walk away. Our proprietary responsiveness metric will give you an accurate representation of actual system responsiveness, and logging will let you examine process activity. Finally, with Process Lasso you can automate all kinds of system settings with rules, persistent process priorities, CPU affinities, etc… This is the real deal, make no mistake! It is intended for power users, but average users can get large benefits by simply installing it. No further configuration necessary! There is so much more. Give it a try yourself!

Process Lasso offers state of the art real-time PC optimization and automation. We do so through intelligent real-time algorithms we’ve pioneered, and also by user-created rules. Run your PC your way!
