Original thread: Performance Mod Glossary
Combining each individual post from the last thread in order to have just one page with all the terms on it. It was too much to flip through 7 pages. Please post more abbreviations that are not on the list and I will update the page accordingly. Sticky this, and unsticky the other please.
