Process Lasso x64 is NOT yet another task manager. It is a process priority optimization and system automation utility. Priority optimization, affinity optimization, core optimization, automated rules, automated power schemes, you name it and Process Lasso has it. Although most consider Lasso the ultimate process priority optimizer, it does so much more! Process Lasso's x64 most popular feature is the unique process optimization technology called ProBalance (Process Balance) that will improve your PC's responsiveness and stability through process priority optimization and/or CPU affinity adjustments. Windows, by design, allows programs to monopolize your CPU without sufficient restraint -- leading to hangs, micro-lags, and delays in your keystroke or mouse actions. ProBalance intelligently adjusts the priorities and/or CPU affinities of running programs, on-demand, as-needed so that badly behaved processes won't negatively impact the responsiveness of your PC. Don't just take our word on ProBalance, try our graphical CPU Eater to see the benefit for your own PC. This is a simple 'CPU Eater' running at normal priority, something any programmer can easily recreate in any language. How many threads running at normal priority, doing nothing other than consuming CPU cycles, do you think it would take to bring your PC to its knees? On a single core system it takes merely one thread at normal priority! Yes, it would almost seem like a bug in Windows, but it is by design, an explanation we also give in the above link. In addition to ProBalance, there are countless features allowing the user to take full automated control of the processes on their PC. You can have a wide range operations performed, or settings applied, each time a process is run. Core optimization technologies allow you to choose on what CPUs/cores a process should run, as well as what their CPU priority class and I/O priority class should be. You can also disallow certain processes from running, log all processes run, and even set various other process rules. These rules, along with many others, include automatically restarting or terminating a process after it reaches some CPU or memory threshold. For license enforcement, you can limit the number of instances of a process that can be running. A gaming mode allows for easy process priority optimization for avid gamers. We must not leave out our power scheme automation capabilities. These allow you to associate specific power schemes with particular processes on your PC. So, when you start a resource intensive process, you can enter High Performance power mode (for example). When it terminates, the previous power scheme is restored. We are adding new power scheme (aka power profile) automation capabilities all the time. Version 5 adds many features, including I/O Priorities (default and current), Default Power Schemes, HyperThreaded Core Avoidance, Automated Updates, and much more. We even offer lifetime licenses for a very small surcharge, so you never have to worry about paying for another upgrade again.
