Does fps capping create more input lag???

[bboysania]

Hello everybody,

without much talking straight to the question. Does limiting fps in pc-games create more input lag, or some latency? The main idea is that the game engine pushes for example 200+ fps to the monitor (with a good gpu), the monitor supports for instance 60hz or in best case scenario 144/165hz (fps) so you limit your 200+ fps to 60, 144 or 165 according to your monitor to have smoother gaming experience. Does it mean that by limiting my fps i create some bottleneck towards my game engine and therefore will get some latency or greater input lag in gaming?

I am a bit confused about how this thing exactly works. Could someone explain it, or give some links, advices etc?

Thanks

In my experience, it's good if you have a thermally weak card that would overheat. I don't notice any extra input lag, but it can make for some terrible screen tearing.

Here you go, this should explain it:

thanks for the video, i saw it already but it doesnt answer my question. is there an official proof that capping fps in games does not create additional input lag or latency in gaming?

I know that using the Frame Rate Target Control in AMD Crimson settings does create a bit of an input lag, although not nearly as much as V-Sync, so yeah, looks like it does.

Compared to Vsync there should be pretty much no noticeable input lag, however depending on the game it could introduce occasional stutter or screen tearing, although you can try going refresh rate minus one (59, 143, 164) to fix it in some cases.

Theoretical example.. when I say your or you.. I mean anyone/varied hardware.

Just an example.

 

While your 60hz monitor may limit your eyes ability, Im pretty sure your high pollrate keyboard and mice..may in some way feel better when non-vsync 100-300fps you cant see but feel...is in play.

Compared to non-vsync fps capped 60-62fps.

We have all seen the frametime millisecond graphs for many gpu's.

If 60fps is 16.6ms and you unlock it and your pumping 120fps constant, 8.8ms...

Wouldnt the keyboard/mouse inputs and game engine sync/update faster..?

Ie less input lag?

Is that the Q?

Maybe you wanted something like this?

thanks for these videos i have watched them too. but they unfortunately still dont answer my question: does limiting fps in games give some additional latency or input lag.

While I'm sure there are theoretical reasons why capping your framerate or using vsync could add a measurable amount of input lag, why not just cap your framerate in a real game and see if doing so added any latency that you can detect? At the end of the day, what matters is that your gameplay experience is up to your own expectations.

No for the input lag. Since its the time it takes for signal of keypress (or mouse movement) to travel from device and to be registered by game engine. You won't notice the difference since at 60 or even 24-30fps input lag is 1 (number for reference). Its not any faster the higher fps gets. Fps would need to be really low, like under 20 to have effect on input lag. Most of the time reasons behind it are from other factors.

 

In my personal opinion it would have major effect on latensy either. We are talking about what you experience more than what really has any effect on gameplay.
