This is it... Portal Done Pro. I, DemonStrate, beat Portal for the PC in under 10 minutes. From when I get out of bed, to the time I drop the final personality core into the furnace, the time is 9:25.567.
Much of the speedrun is sitting in the elevator. I have not calculated yet how much time I waste waiting for the elevators, but I'm sure it is probably a majority of the time.
I segmented the speedrun per map. This means when the game says, "Loading...", it is loading a new map, and I save the game and load from there. The only exceptions are Chambers 02 and 13.
This speedrun uses a majority of the glitches in the game. Unfortunately, it does not use the acute angle glitch, which might be the most useful glitch in the game, if used correctly. All other glitches are explained in my series of commentary videos here: http://www.youtube.com/view_play_list...
This video is not for the weak of heart. It is very fast and very confusing for someone who doesn't understand the glitches used. I would highly recommend watching the videos above.
I don't believe anyone else in their right mind would try to do what I have done in this video. I completed the first segment on September 13, 2008, 06:12 AM and the last segment on July 03, 2010, 08:32 PM. Almost 2 years of working on this.
I've removed the old torrents I had here. Instead, I've re-encoded the run and put all the files into the same torrent. If you only want to download one at a specific quality, use your torrent manager to only select one of the files. The torrent contains: High, Medium, Low, and Mobile quality MP4's: http://dl.dropbox.com/u/45123651/Port...
