Frames Per Second

[ACG_pezman]

So I was browsing the website reddit and noticed someone had posted a picture as a reference to FPS. 

 

Now there has been a lot of debate on these forums about what an optimal frame rate should be.  Now I am in the camp of higher FPS, I strive to maintain at least 60fps, but I know many people here (even some in my own squadron) who claim that it makes no difference.  I have heard the argument that the human eye can not distinguish past 34fps, but I have always thought this false.

 

Anyway, for those of you who don't know or really care what a good FPS is, this image will show you the difference between 60, 30, and 15 FPS.

 

 

Notice the difference between the 60 and 30 fps, very distinguishable.  Even without the blur effect 30fps can very slightly stuttering which can cause contacts to blur and blend into the pixelated images.  So, if you are having issues finding and seeing targets or contacts, getting higher FPS may alleviate that issue.

 

Enjoy!

You should see that image on my 720p monitor with crappy refresh rate, it has so much ghosting it's scary!

The whole 30fps limit to the human eye is false. There are a number of sources but Wikipedia is the easiest.... The human visual system can perceive up to 1000 frames per second although realistically anything above 150fps is indistinguishable.

 

https://en.wikipedia.org/wiki/Frame_rate#Frame_rate_and_human_vision

 

Ideally for games I like to keep my frame rate average around 50-60fps and my max as high as I can make it. Sometimes that only means getting up to 70fps but I think most crucially is the minimum FPS. If you have spikes or drops and you suddenly drop below 20-24fps on a regular basis then that is not great for having that uninterrupted feeling.

Buy a 144Hz gsync monitor, and FPS wont matter anymore, in IL2 I have 28-90 fps (playing in 2K) and theres no difference between them, g sync is taking care of everything

ok. no problem. ...but....

.

higher resolution causes lower FPS. so, as you try and get the edges and details more clear with resolution, you push the wrong way on FPS. i'd rather my FPS be 120 (saw some comparisons between 60 and 120), but i'd also like a 4k resolution. right now, with the software (DX9) and an i7 with a gtx780(fast) at 1080p i average between 45-60 FPS. i want to go 4k, but im afraid of the FPS hit. wondering what DX11/DX12 will do. wondering if VR2 is the answer.

Yeah, I'm hoping that dx11 will bring a lot more performance out of the PC, I have two 770's and an i5 and I get the same frame range you do. Thing is I get lag when lots of stuff is going on in the server, but my frame rate doesn't drop. Makes me wonder if the old architecture of dx9 is the reason for it.

In fact it has been said that the human eye cannot sense fps above 25.

But personally I find that this isn´t true. The higher the fps the smoother it seems.

Just note that the next limit is Your monitor refresh rate, so that will be 60 or 120 hz (fps one could say).

 

But equally important is that the FPS must be consistant.

If FPS flucturates between 90 and 50 hz, then You will experience stutter, which can be more of an evil than low fps.

 

Personally I would like consistant 30 fps, than flucturating fps between 90 and 50 hz.

 

It´s also game dependent.

I have seen games running at 25 fps, that still felt smooth, but also games than ran at 50 fps and still felt choppy.

 

In the end it´s quite individually when people find a game to run smooth. Some say they cannot live with FPS below 60, while others find it Ok at 30 fps.

 

So don´t put too much into what other people tell is perfect, but setup the game to run they way You find acceptable and then learn to live with the stuff You had to turn down and try not to keep looking at any FPS counter.

The 30 fps is misunderstand. Human brain perceive, objects which change position on still images when they are shown at least as fast as 24 per second, as continuous animation.

For me 30 fps game is barely responsive enough and 60hz monitor with average input lag is also not pleasent to play dosen't matter if game is drawing at 100 fps or more.

Which monitor do you use?

i think the point of the OP and me is NOT about the game necessarily running 'smooth' so as to eliminate chops/stutter, but that the faster FPS creates a clearer, more defined subject in motion. the illustration shows clearly the 'blur' difference between 30FPS and 60 FPS. i've seen comparisons between those that also include FPS into the 100's and it gets even clearer. this is most noticeable with fast motion objects. i was surprised when i saw it and skepticism about the benefits were erased. in a game where your success depends upon spotting/discerning moving objects, it is certainly a benefit beyond just smooth gameplay.

.

DX11 sounds like it might improve the FPS but your point about the monitor refresh rate is STILL going to be a factor. my current monitor is 60hz so, even when the FPS says 100FPS, my eye is seeing 60Hz refresh (=60FPS). the game will run 'smoothly' at 60x. but IF the game is showing that my system, minus monitor, is running at an FPS above 100 consistently, then its time to look into a 144hz monitor, and hope i can afford one that is 4k and big...then id want 3 of those! and they need to be curved.

And just to clarify: I guess one would need an nVidia graphics card for G-Synch to work, right?

For G sync yes, but there is AMD alternative, i dont know much about it, but its called Free sync, and there are monitors which support that, this was first IPS monitor with such high refresh rate and this technology so i didnt really have other choices, but theres plenty of other monitors out there now, both with gsync and free sync support, my favourite would be this i guess:

Look into my post again and see that what I mean is that high FPS doesn´t mean stutter /non choppy free experience.

Low fps will cause constant stuttering, while flucturating fps, even when flucturating at high fps will cause stutters and choppy gameplay.

.... thx. i see now that you mention stutter as another consideration (not just blur). thx for calling attention to it.

.

my own experience with PC gaming is very limited, and this is the only one i play now. personally, i havent noticed stuttering while the FPS fluctuates (my pc this game). it gets choppy when the FPS goes low, though. so far, so good. hopefully i wont get those problems when the equipment/software is able to push the higher FPS's!

i have an RC simulator (realflight) that shows extremely high FPS's on my PC. the FPS numbers fluctuate, but i dont notice any stutter there, either. wonder if my hardware compensates.

[1PL-Husar-1Esk]

High fps fluctuation are not causing sttuters or choppy gameplay. They can cause only tearing and that can be eliminated by G-sync monitors or vsync.
