How Does Frames Per Second Work?

[Dooley]

As im new to graphics card can anyone explain about frames per second to me? e.g. Like is high frames per second is better than low or the other way around.

Higher is better. The more frames drawn per second, the less likely you are to notice any kind of stutter in the image.

A slow fps is like a slide show.

At 30fps or better, and most people cant even notice it.

Actually i did some reading up on this, since it is constantly brought up in games (like cs)

You can see over 200 fps, but at higher amounts of frame rates your not going to be able to notice something like a tiny spec, moving in 1 frame to the next.

You will be able to see major changes, like if the screen flashes red you will notice the difference.

The more fps=the more fluid the motion is going to look.

Thanks alot both of you.:up:

Couple of things to add to the info above;

LCD's will only show 60fps max since that is the limit of it's refresh rate. (more expensive monitors will go higher)

_good_ crt monitors will run at 120hz so that with the proper equipment (a quadro card and shutter glasses), you can do full motion 3D. (since each eye _wants_ 60 fps to make it look good).

Shutter Glasses (http://en.wikipedia.org/wiki/LCD_shutter_glasses)

so i guess i should set crysis high and grab a set of shutter glasses.

The glasses would only work if the program supports them. The software needs to be able to switch the images for left and right eyes to be effective. Also there are no consumer gaming cards with a stereo connector. Most of the quadro cards and firegl cards (except the low end ones), have a connector on them for the stereo transmitter or wired glasses. (I have both kinds...)

A little more clarification. Games have a renderer to take the code and make an image. Each update to the game is rendered as a new frame, and the frames are then played in succession to each other. The higher the FPS (frames per second), the higher the UPS is (updates per second). Sometimes, games will do an update, but skip the frame for it (so other processes can catch up to the update). If you have fast enough hardware that you can update a certain amount each second and render the same thing, you'll have fast updates and frames. Like D1337 said, slow would look like a slideshow, and high would look like a movie. High UPS and high FPS = most fun.

The human eye cant tell the difference from anything above 70fps. Like what has already been said, the more frames the better the picture.

Read the article that D1337 posted about "perceivable FPS" and you will find that the human eye can detect well above 200fps.

It is a good article too.

WOW! thanks to everyone above for all the great info. Cheers

I was reading an article about CSS gaming and they said the human eye cannot be effected by anything over 30 fps... yeah RIGHT. I played CSS on a tournament machine at a recent lan on a 6800GT, and even though it was running at 50 fps, it seemed laggy compared to my 8800 running at 230 fps.

That may be so that the eye can DETECT well over 200fps but do we NOTICE the difference of anything over 100fps?

That's what I meant in my previous post.

Some food for thought ;).

[Spawn-Inc]

well we don't in movies, i'm not sure how many fps it does but, it looks fluid to me.

[The boy 4rm oz]

According to that article they run at about 24 fps but when I play some on my PC they are coded for and run at 30fps.

Humans can't recognize past 20 FPS

[xRyokenx]

My mind is slow. I see about .00012 fps. Like typing is... weird. But if you really are typing, then it's just fine.

Well, I figure I can recognize upwards of 70fps but it gets harder to tell the higher the framerate.

[The boy 4rm oz]

I guess there can't be a set answer for this question because everyone is different and will notice different fps's.

[FuzzyPlushroom]

Definitely. Racing games, to me, are smooth at 20-25 fps... FPSes are generally about 5 fps higher to be completely smooth. I know they're not, but my eyes don't, and that's what counts!

Exactly my point, I installed the Colin Mcrea DiRT demo yesterday and with everything on high at 30-35fps it runs so smoothly. Personally I think high fps is only needed in shooters. Try playing BF2 at 30fps, aint going to happen.
