Not sure how many use AlacrityPC but it is an upgraded sequel to FSAutoStart (FS2004) which turns off background programs to allow for more resources to be available/utilized for flight simulation (or any other "game!"). When you close flight simulator (or any "other game!") all background programs and services will turn back on for normal pc ops.

I came across this guide written with the blessing of Ken Salter, creator of AlacrityPC and thought I would share the wealth so to speak.

IMHO this guide is to Alacrity as Nick Needham is to FSX.
