So I have the latest release of carbonite, fresh installed wow, and I've just installed x-perl, and carbonite addons. Wow says what this addons is out of date. I try to load only one carbonite addon and fps is about 14-15, then i turn it off fps are bigger. What is more I tried carbonite with my computer and with laptop, and the same problem. So i think, that carbonite is not ready yet for cataclysm, because what i found in WoWWiki cataclysm addon status "Addon does not generate Lua errors but does not work in general. Also, the addon appears to eat your framerate."
