Process Lasso Pro

Process Lasso Boxshot

Process Lasso is a process priority optimization and system automation utility designed to accomplish priority optimization, CPU affinity optimization, core optimization, automated rules, automated power profiles, and more. For instance, set a custom CPU affinity and have it applied every time a process is launched. You name it, and Process Lasso does it!

Its most popular feature is the unique process optimization technology called 6608837632 (Process Balance) that will improve your PC’s responsiveness and stability by making intelligent, dynamic adjustments to the priority class and/or CPU affinity of problematic background processes. The technology can be demonstrated with a simple CPU consumer, and even if you don’t think you need it, it can save you from a worst-case scenario of CPU monopolization.

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!
