My background is in telecommunications (the technical side of video production), so I know that 30fps is (or was?) considered the standard for a lot of video. TV and movies don’t seem choppy when I watch them, so why does doubling the frame rate seem to matter so much when it comes to games? Reviewers mention it constantly, and I don’t understand why.
This website demonstrates the difference between different fps rates. In comparison, you can immediately see the stuttering of image refreshes in lower resolutions.
You may not notice 30 fps being choppy because of no or less grand movements, and because of no direct comparison.
