I just uninstalled a game I had on my computer, http://www.youtube.com/watch?v=Ji57wnNFAJ4, and seem to have had a massive speedup. It's really weird because it's a really tiny freeware game. I uninstalled it with CCleaner, a utility program for the registry I have installed. I really needed the speedup because my laptop has been running strangely loud and been getting too hot. Maybe because it's an indie game and isn't optimized well. I think it has to do with the registry.
