It would seem that some people are just more sensitive to things like frame rate and screen tear. I cant stand screen tear....but some don't seem to notice it.
I also wonder how many people who claim to not notice a difference between 30 and 60 fps are using tv's with frame smoothing enabled and don't even know it.

Some of you are honestly telling me you cant see the difference between the 30 fps and 60 fps ufo's in that test? 0 difference whatsoever?
If you can't then more power to you, but the difference is startling to me and tons of other people. You can tell how much detail you lose when running at a lower frame rate and you are in motion. Go back to the ufo test and increase the speed to 1920 pixels. Its pretty easy to see.
I understand what you are saying OP. I kinda feel like 30 fps is being used because we had such high hopes/expectations for this new gen after last gen being out forever and we still have problems running 1080p with decent framerate. So the obvious choice to make the graphic fidelity higher is to run 30fps. Just an opinion, not sure how much validity is here.
