120hz —> 60hz

[Lord Foog]

Why is it when on a 120hz monitor you switch to 60 hz and mouse input lag occurs, and isnt smooth, even though there is stable 60 or 200+

[Supafly]

Not entirely sure what you mean.

I assume the 60 or 200+ refers to fps?

Mouse feels smoother at higher hz. Even when moving it across the desktop. Cutting the refresh rate in half it also going to cutting that smoothness is half.

[Lord Foog]

But when i switch from 120 to 60 hz then the mouse gets input lag. And how do people make videos so smooth on 60 fps??

[_I_]

desktop can keep up with 240+hz displays and look even more smooth on displays with very low response times

hz is the max ammount of full frames per second the display can show

Could be the monitor. If it supports high refresh like 120hz, use that for everything, desktop, games, etc.

Recording on such a system at a locked 60 fps shouldn't be slow or hurt anything.

Doesnt matter if the monitor is 120hz. If you run it at 60hz, it will feel like 60hz, aka, not smooth.

Here's why -

the short answer is the game engine runs faster

Plus after you can used to a certain refresh like 120, 144, 240 and then switch back to 60, well yea it feels slower... It IS slower and you may feel the mouse tracking feel or look slower.

If you have a screen that does a certain res and refresh use that, always.

It feels laggy because you're getting half the updates (refreshes) in a second. So you have to wait twice the time before your input is seen visually, resulting in input lag.
(120hz = 8.33ms per update, 60hz = 16.66ms per update.)

So, if you can, always run in 120hz mode, it'll make games, browsing, and such much smoother.

Frame pacing, perfect frametimes.
If you've got 1 frame that takes say 8ms to render, then another that takes 10ms, then another one that takes 8.5ms, and then another that takes 9.8ms, it's going to look juddery, not smooth, laggy, etc.
Whereas, if you have perfect frame pacing, every frame takes say, 8.33ms to render, it's going to be smooth as ♥♥♥♥, and would look smoother than a higher framerate (lower frametime) that is swinging around a bit.
Games also look nicer with a fixed frametime. (I recommend using RTSS to cap FPS, as it limits at a CPU level so you always have the same frametime (unless you're unable to keep that FPS constantly.)
Also, an added bonus of limiting FPS, it reduces GPU usage, which in-turn reduces input lag. (So long as you're not above 95% usage, you'll be fine input lag wise.)

I recommend trying it out, even if you don't care about the reduced input lag part.

What? How does the ''game engine run faster''?

If you're running it at 60hz, IT IS 60HZ.....
It won't ''feel like it'', it will be it.

But the thing is that my fps is fixed to 117 in nvidia panel (new feature) and i have gsync but it varies between 115-117 which has microstutters

Cap with RTSS.
