Koroush has posted his latest guide; this time for Oblivion. This is one loooong sentence:

"My main aim in writing this guide was to sort out the fact from fiction by personally testing all the .ini file options and performance tweaks floating around and document only the safe, working ones; to accurately describe all the in-game settings correctly; and draw together all the available sources of optimization and troubleshooting information into a single reference source which will remain up to date as we find out more about this amazing game."
