Does FPS even matter?

25 fps is the point at which the eye can be fooled into thinking what it sees is motion instead of a series of flashing images, but ofcourse as it increases so does the quality, we can tell the difference between 25 fps and 60.

25 is just the opening frequency.

That's about it really.
 
Remember that your GPU really needs the capacity to supply MORE than your target frame rate since if you're running at 30 fps (with vsync on) and your scene gets very slightly more complex, you'll suddenly drop to 20 fps. Lurchy.
Ever wondered why so many console games are locked at 30? We've shipped a number of games which could almost pull off 60 all the time but the jumps down to 30 would distract people, hence the 30 lock.

I'd be surprised if I showed someone a game running and they could tell me the fps if it wasn't choppy.

Also surely given the various programs you can use to display the fps, a certain amount of the differences seen in different fps's is down to the human brain? If you know something is supposed to be a higher fps, then you immediately expect it to be somehow smoother.

Of course technically it is smoother but would there be a perceptable difference between say 40-60fps if you did NOT know the fps on screen.

I can Vsync grid to 60/50/40fps & i don't need a fps counter to notice the smoothness difference.

I remember playing DO3 on my xbox at 60hz 60fps & i was doing some testing & by mistake i put it on 50hz 50fps before switching it off & the next day after work i turned it & the moment did not seem as smooth as i remembered & thought what's up & looked in to the setting to see that it was at 50fps instead of 60fps.
60fps is a minimum for me & i cant wait to get hold of a 30" 2560x1600 120Hz monitor.

If you are running a constant fps such as say 60 for sync then you'd notice a massive difference if it dropped to 30 although if 30 runs smooth in game will work just the same

That depends on the game & its pace.
I can not stay on the road in GRID at 30fps.
And also if you could not see the difference then the changing of fps should not be notable.

the more FPS is better, the 30 FPS is an average (you may get 59frames in the first 0.5 of a seconds and 1 frame in the 2nd 0.5 of the seconds)

This would not make the game smooth at all....
 
The player movement/physics is real time and relative to some constant tick/timer in the game. The graphic card tries to keep up and render the world.

Low enough FPS and your are only going to see a few frames every few yards in your game world and thats pretty crappy :) kind of blinking fast as u run down the street.
 
aye; GRID is a good example; I've got a 3870 x2 powering it; and still its not as smooth as i'd like at 1920x1200 :( Im sure that its mostly got a higher framerate than crysis; but due to the nature of the gameplay the fps needs to be higher. I always played the NFS games on minimum details; simply to get the max fps required. Obviously with strategy games its no problem, and fps games usually have good mechanisms to keep stuttering to a minimum even during framerate changes.
 
The eye can detect more than 30FPS it has been proven but i cant remember where. If we could only see 30FPS all games would be limited to 30fps which they arent!
 
This is from a vague memory so please no attacks. I think I can remember watching something that talked about fighter pilots and something about that they can see at up to 200FPS. I know, very little information that explains nothing but I did say I can't really remember :D.

I believe that it was a picture of an aircraft shown on a screen for a 200th of a second and they saw it. As for me, usually anything over 50FPS is fine (average framerate), but I'm fine with 30FPS so long as it's a constant 30FPS (i.e. no dips) as that gets really distracting. Then again, I was playing Nexuiz the other day and was getting FPS of over 200 and it didn't feel very smooth at all, but I think that might've been down to my mouse...

Also, no, you wouldn't get from point A to B with higher FPS as since the 90's games have used a technique called 'framerate independant movement' where movement is ultimately determined by time elapsed, not by the frames being processed.

I am confused :confused: seeing as the eye can't see more than about 30fps, is there any point in being able to get more than this? Eg: If you are getting 32 fps and you run from point A to point B, will you get to point B any slower than if you were getting 125 fps?
