Motion/jittery problem in Flash

Hi guys,

I’ve been struggling with this for about a week now.

I am trying to make a simple object move across the screen, but I am running into the problem if it being jittery and choppy. I tried to adjust the frame rate, but it didn’t help much.

I am not sure what to do next. I kind of thought something as simple as this would flow a lot nicer, especially since Flash is supposed to be known for doing good animation, but it just doesn’t look great.

I am running Windows 7, 64-bit, 8GB RAM, Quad-core 2.4ghz processor.

I have attached the .fla file. Also, here is a link to the swf file: http://legionofderp.com/testing-sword-03.swf

If someone could take a look and give any sort of helpful device, that would be awesome!
