why more FPS?

[Bmxpunk86pl]

if the human eye can only see like 30fps then why do ppl want more fps? like 60fps? i mean if ur a fly or something then yea u will need more fps but i dont think flys play quake 3

Several theories.

Minimal framerate to fool the eye into seeing fluid motion is 24 interlaced or 30 single frame.

But for gaming it's different. Extra frames can be seen, it adds vitality and life-likeness (no, that's not a word) to the environment. Our eyes are sensitive enough to discern them. Also, during action, it allows the PC some tolerance so it can drop some frames and still look good.

A higher FPS also makes your aiming smoother, assuming you have a decent mouse. Atleast thats how I feel. I am perfectly happy as long as I get a minimum FPS of whatever my VSYNC is (usually 85). Keeps the game smooth and no tearing. I beleive 60 FPS is considered the minimum for gaming?

That depends on the game. max Payne at 40 fps is steady, but UT looks choppy at 40.

higher FPS=smoother gameplay. The difference between 100 and 200FPS may not be worth mentioning, but the difference between 45 and 60 sure is!

As Rav mentioned-
Keeping Vsync on when your system has a minimum FPS equal to your monitor's refresh rate can make a game look amazingly fluid. Even better than leaving Vsync off and getting 300FPS. To high of an FPS can actually hurt the gameplay, believe it or not!

Personally, once I get an average FPS over 45 in a game, I consider that game perfectly playable. If it hits 100, I give up on tweaking- it's fast enough for me!!:D

i thought the same thing about fps but i used to play my games with my rage fury pro(everything maxed out) and i was happy with 35fps, now im happy with 50.....

Does this thread seem to bring back memories???;)

Well, although my computer is so weak it can't push a descent frame rate (I'm talking like around 10 or 20....), I can only guess what the diffrence looks like. However, I think why you want more than 30 goes something like this.

30fps is not as fast as your eye can see. At this point (or near it), still pictures appear to become blended together and animated. Above 30, everything is still animated, but your brain can still "see" each frame. As you increase the FPS more and more, your brain "sees" less of a pause between each frame, and so what your brain interprets is more fluidic. When you have a REALLY high frame rate, your brain can no longer see each frame, and so it feels more natural than at something lower (like 30).

Remember, this is just an oppinion... I just wish I had the hardware to back it up! :D :D

technically a movie (film) is 24 full frames per second, tv (ntsc) is 30 frames/60 fields per second. each field shows half the lines (first field will be all odd lines, second will be all even lines, etc). while this does give a good appearance of motion. these are also photographs, per say.

a camera will take a fast moving object and since it's shutter is open for 1/24 of a second, it will blur that object for the ammout it moved in that time frame. so a fast moving object isn't (on film) a clear picture, it is a somewhat blurred object. take for instance a quick action segment of a movie and pause it (tape or dvd, wont matter), and you will see a person's arm (or whatever is moving) blurred.

a computer geometry file, however, is a clearly defined object (assuming the hardware isn't doing its own motion blur). so if you see a fast acting 3d geometric shape move across the screen, you will get more of a choppyness, as there is no motion blur to "smooth" out that object moving from point a to point b in the next frame. this is overcome by inserting more frames in that period of time, which fills in the inbetween area with movement (this is where the 30fps tv show is blurring the fast movement).

as i do 3d renderings all the time with 3ds max and lightwave, the results simply are not acceptable at 30fps if i do not have the program use motion blur on fast animated segments. if no motion blur is included the object is choppy and ends up getting the same bad results as a 3d game that doesn't have enough FPS.

::edit::

i'd be glad to post examples but i believe they would be much too large in size (uncompressed NTSC is 30MB/sec). but if someone has a fast connection and wants to see, i could send an example if you want.

wow thanks a lot for the info, by the way what is vsync? how do i turn it on or off on my tnt2 riva 64

go to your vidio control pannal and crank the refresh rate down below 75 and watch what happens.. you will definately notive a flicker:cool:
