AlacrityPC is a utility designed to help you get the most performance out of your computer when running resource intensive applications, like modern games. It does this by shutting down unnecessary services and programs before starting your application. When you finish your application, those services and programs can be automatically restarted.
AlacrityPC also provides some additional optimizations, like memory defragmenting, removing your desktop background, shutting down the desktop shell and Vista Sidebar, and forcing background tasks to execute.
AlacrityPC is the sequel to FSAutoStart. It is written in C# .NET 2.0.

    If you are running a DAW (Digital Audio Workstation), this little jewel will help you shut down all the junk you don't need while running your audio production software. In my case, Cubase 6. I was able to squeeze every bit of power out of my computer when recording and running VST plugs. Great tool for tweaking performance!

    I tried this program with Flight Simulator X on two flights, one to Boeing Field, and the other to Seattle-Tacoma International, in Seattle, WA, Prior to using this program, FSX would always freeze about 10 miles from the airport. With use of Alacrity PC, was able to complete both flights successfully. I used stop then restart on a number of services and programs. It worked beautifully! Not sure which services or programs were causing the freezeup, but everything proceeds as the manual says. Even included a time delay so I can start Active Sky 2012, then enter my flight plan and download Active Sky weather before starting FSX. I am one very happy camper! Jim Kaye
