Someone who can explain why we all have different opinions.
I'll put this out there for the people that can notice a difference between 30fps and say 60fps, can you acurrately describe the quality difference. Are things smoother? Quicker? More fluid?Less laggy? Just saying that 60fps is noticiably better isnt enough. An accurate explaination of the difference would be nice.
Check the link posted early on this thread that allows you to directly compare different frame rates. At higher frame rates I see a more accurate representation of the original image as it moves.
We know that what we watch isnt actually something moving, its a rapidly changing set of still images. The higher the rate at which they change the harder it is to pick each individual one out and the closer you get to fooling your brain into thinking it is seeing a moving object. Your eyes can detect the frames even at very high frame rates because they are used to viewing the real world which in a very hand wavey sense has an infinitely high frame rate. So in comparison even 60 fps is pretty low. However when you play a game or watch a movie or whatever you let your guard down and get immersed in what you are doing. You are expecting to see moving people, cars environments etc so that is what you see, you dont log into BF3 and think " Oh no! here come some heavily armed polygons frame by frame". Its like when you raed a wrod wiht the letters in the wrong order and can still read it easily. Your brain is good at and infact actively looks for patterns, faces etc all the time so it is easy if in the right frame of mind to fool it into seeing what you want it to see.
Anyway to answer the question why do we all have different opinions?
Taking that lump of text above into account the degree to which you notice a difference in frame rate will depend on how engrossed you are in the game and what you are looking for. If you are expecting to see what the game is trying to make you see then you will probably be happy with a surprisingly low frame rate. If you are conscious of frame rate and therefore looking for its effect on the images you see, even on a subconscious level then that is what you will see. Some people will find it easier to accept the optical trickery than others, hence the difference of opinion. So let your guard down and get immersed, but higher fps is always going to help.
