Does using ingame fps limit give input delay?

[Varsik]

A lot or not a lot?

[Blaquicat]

Nop, only vsync has, because it "wait" for the screen to be ready to synchronize frames with hertz..
Capping framerate without "waiting" dont give input lag.

[Autumn_]

Depends on the game, and how well the frame limiter is implemented.

Generally though, no, it won't add any extra latency. But it won't be as consistent as something like RTSS.
Which would give you near perfect frametimes, for a marginal increase in latency (you'd be hard pressed to see a difference, in extreme cases.)

Not true.
There's various forms of frame limiting that cause input lag.
RTSS does, because it tells the CPU to wait before sending data about the frame to the CPU.
Some game limiters add input lag because they tell the GPU to draw at randoms times. Others will draw as soon as possible. It all depends.

V-sync isn't the only thing that adds input lag. You've also got things like G-sync, Freesync, fast-sync. Game processing, frame draw speed/time, monitor latency, pixel response time, mouse response time/update rate.
There's lots of things that cause it.

Not as evident as vsync is.. for sure..

But is RTSS input delay very noticeable?

Been playing with Vsync on since forever. Only a few games what I remember have noticeable input lag.

Dead space
Fallout 4 (Could be fixed with editing configs. Mouse Acceleration was the culprit in this case what I remember.)
Rage

Every other game feels spot on for me where I can't detect the input lag. It's not that I've gotten adjusted because the moment something isn't instant for me I'll get annoyed.

So I'm wondering if it's just something people will claim because that's what everyone else who dislike the feature.

[Blaquicat]

I didnt had that lucky, with my rx570 (and my old 650 boost) i experienced several input lag with vsync on, l4d2 even had tripple buffering and stuff, still lags like hell.. i had to turn it off..
Even fallout games and skyrim have input lag for me..

As someone who is extremely sensitive to latency (and scores in the top 99% on humanbenchmark reaction time test)
I can say, I have never felt any latency added by RTSS.
It's not impossible that you couldn't, depending on the situation, but I highly doubt it.

Plus, when you have <95% GPU usage, you have lower input latency anyway, reducing it by 3x what RTSS could produce.

And a nice stable framerate does wonders for muscle memory and consistency. And your eyes.

I've personally tested it all, V-sync, G-sync, ULMB/ELMB, RTSS FPS caps (at different intergers of monitors refresh rate), RTSS scanline sync,

And in my experience, V-sync always added so much latency, I couldn't stand it.

You may not think you do, buy by nature, you grow complacent with it over time, you learn to accept and adjust to it.
So it is partly to do with 'growing into it.'
And partly to do with natrual ability, reaction time, preceptive ability, thought processing etc.
I have an extremely high reaction speed, and I can fell the differences between vsync on and off, different high refresh rates, and different frame rates.
I couldn't use V-sync ever again, unless my ability to notice it fades extrenely fast with age.

So, my personal thought is, if you're unable to see the input lag, good for you. You're lucky.

Same boat here, all has latency.
If you want a tearing controlled experience, try RTSS's scanline sync.
You move the tear where you want. And you get nearly no added latency.

It's not about me not being able to feel/see it. It's just not there. Not in any noticeable way.

I'm not bad at FPS games either. I've banned for "aimbotting" in Counter Strike Source and Battlefield series quite a bit of times which puts me above most people. My eye sight is perfectly fine too so that can't be the issue.

The games I mentioned before though, that's where I could instantly tell something was wrong because the input delay was massive. To the point where it was rather broken.

But in any other other games I play on 65 FPS there is no input delay. Even tested without Vsync on and still no difference. Also due to a 60 Hz monitor overclocked to 65 Hz I'd probably not be able to see the FPS difference other than getting more jaggies on the screen.

I can feel the difference in FPS though when it just hits 50 to 55 and lower. I feel it right away.

Not in any noticeable to you. But to me, I can feel the difference between Vsync on and Vsync off at 144hz. (It's still very playable with Vsync on at 144hz, but I can still feel the slightly latency.)

I'm not saying you're bad, or defective, or whatever you may call it. I'm just saying, you have a natural inability to see the latency difference. Lots of other people share it too - I've seen people that say they can't see a difference between 60hz and 120-144hz.

And, if you can't see the difference, like you claim, then I am envious of that, I would love to not feel the latency difference, I really would.

I'm not quite sure what you mean by ''Also due to a 60 Hz monitor overclocked to 65 Hz I'd probably not be able to see the FPS difference other than getting more jaggies on the screen."
Are you saying that you can only see as many FPS as the monitor refreshes a second?
And, are you calling tearing 'jaggies'?

I never said I couldn't see the difference between 60 FPS and like 144 FPS. I just said I don't know if my monitor could display it because it's a 60 Hz monitor and things doesn't get smoother when I run it at higher FPS due to the monitor not able to keep up with the FPS. In fact it just gets far more jittery with higher FPS and make things look worse.

I'm pretty sure I could tell the difference between 60 FPS and 144 Hz because I instantly feel when the game even goes to just 55 FPS and I know there is a noticeable smoothness difference between 60 and 144 FPS.


With Vsync I'm sure there is a setting that causes this. A setting that I'm not using. I could be the result of a few things together that makes it go away or reduced to such small amount that it makes no difference.

Seeing how Fallout 4 had massive issues with Vsync due to Mouse Accceleration but that could be fixed.

But, you said you didn't feel a difference on your 60hz monitor if you got higher FPS...

What do your monitors update rate have to do with FPS?
With higher FPS, you still get lower latency, and a more up-to-date frame being displayed.
And, technically speaking, a 1080p 60hz monitor can display up to 64,800 FPS (in the form of partial frames.)

It would get gittery if your FPS is at some odd value, you usually want an integer of your monitors refresh rate.
And, if you go above your monitors refresh rate, you want to get really high above it, to minimise tearing between different frames.

Well, when I tested, I had a 144hz monitor, and I did a few tests where I had an RTSS FPS cap (So I had near perfectly smooth frametimes, and I had <95% usage, so I would get less input delay, but no sync), then I tested with just V-sync (So I wouldn't have any help from RTSS smoothing frametimes), and I tested with RTSS + V-sync (Which produced a nice middle ground between the two.)
And I could still feel latency differences between them all. First RTSS only, then RTSS + V-sync, then V-sync only.
Sure, it's a very minimal latency increase at 144hz, but I could feel it.
At 60hz, you're pretty much garanteed to feel input latency from V-sync, even with triple buffering. Since by design, it forces frames being displayed to wait. You cant stop something like that having latency. (At lower, <200hz, refresh rates.)
