I posted this on the steam forums and users have said that it seems to be running too fast on my machine.
here is the post:
I have been having trouble with 3-1x for a while, even to the point where I stopped playing a bit because of it. I searched youtube videos and found that people beat this level easily. The reason? The buzz saws literally move at half speed in the video. This naturally made me saw WTF, so I decided to boot up fraps and take a video. Once I hit record, I noticed these saws move at the same rate as the videos, but meatboy seemed to move at relatively normal speed.
I guess people running at 60 FPS get punished more than people at 30 FPS :-/
here is a video of what im talking about (30fps):http://www.youtube.com/watch?v=B6MByny26s4
here is one I made which is not very exciting, but you see the difference. (60fps)http://www.youtube.com/watch?v=JhKhkHrLSK0
