Prio (keep 1-core-affinity setting)

Many people report that a 1-core affinity setting "fixes" some SA problems. ~~~ Without 3rd party software that setting has to be set every time the game is run. ~~~ Prio saves settings made in the task manager. After rebooting to complete the installation, set the affinity to 1 core in the task manager(http://i.imgur.com/O3eYtxn.png). You should test if it has worked. (external link)
