I've been coming across all sorts of bugs in Skyrim, but one of the biggest annoyances that I have experienced so far is what happens when you open a door that has items nearby. It flings all the items in a 10 foot radius around the room you're in almost always resulting in injury to self. I figured I would record the issue with fraps and post it on youtube for discussions on a fix, but time and time again I could not replicate the bug while recording. It dawned on me after about the 3rd attempt that when I have 60 fps (which is what fraps locks to when recording) the physics seems normal, touching items doesn't cause them to shoot off at 50 mph and hurt my character, jumping onto carts doesn't launch me into the sky, etc. Rarely these physics bugs happen outside, which is when I rarely have over 60 fps.
Even moving objects or bodies at 60 fps is a completely different experience than trying to moving them around with 200 fps. I insist that everybody who has forced Vsync off and are having issues with the physics you try it yourself. This might be one of the reasons that Bethesda chose not to have an option in the launcher to turn off Vsync. Seeing as how the Y axis of mouse movement is also affected by framerate this might just be the case.
