Input delay measuring?

[frank meadow]

I think it would be so good if in the future Lossless scaling has a built-in input delay measuring tool so you can measure by yourself and test all the different settings and find what's more suitable

[whole wing]

you can measure input delay through the nvidia app

[frank meadow]

that's frame latency not input latency

[whole wing]

there are various apps to help you track input latency

[frank meadow]

cant find any
do you know any?

Actually measuring input latency requires a connection with the mouse and display, and often involves expensive equipment

You either need to build your own device to measure it or buy something crazy expensive like an Nvidia LDAT (which is pretty much just for businesses)

There's software like AMD's FLM that can measure latency with a test, but it doesn't work well with LS on all GPUs and doesn't include mouse or display latency

[frank meadow]

what kind of latency does FLM measure ? I think frame latency? if so what's the difference between that and input latency

and what kinda of tests should I do with FLM to make sure it's working fine with me?

Thanks for your time

It's pretty much just whatever latency the game has. It's good for comparing one scenarios latency to another, but take the numbers with a grain of salt.

[frank meadow]

yea that's exactly what i've been looking for
i wanted to compare latency between gsync on/off, using nvidia reflex/not using it
and different settings in LSFG see what's lower in latency

but i just heard that program doesnt work with LSFG so idk if i should even try it because i would just trust the numbers and maybe i shouldnt lol idk

[noble gazelle]

Well, if you're using DXGI in LS, LS becomes noncapturable, so you'll need to use WGC. And if you're not on 24H2, you're out of luck for Nvidia cards

[frank meadow]

how can ik my win version?

[noble gazelle]

AMD cards work with LS when it's using DXGI because they use the AMF capture API which can still capture LS. But on Nvidia GPUs they use DXGI which conflicts with LS

[noble gazelle]

Press win + r and type winver

[frank meadow]

yea i saw my LSFG settings and i use DXGI
and im on windows 10 22H2

i have a nvidia card as well

[frank meadow]

so i guess it's not worth it to download then since it wont capture it
i wish there was a better way of measuring latency :-

[noble gazelle]

Oh... Yeah, 24H2 is a windows 11 thing

[noble gazelle]

Sadly, it's effectively impossible for there to be a miracle app that does this

Since hardware is a large part of the latency equation

[frank meadow]

yea maybe future monitors can calculate latency somehow if they care enough to add that as a feature in a monitor

[noble gazelle]

It's a thing, but only on very few monitors, most of which are expensive af

[frank meadow]

hm so i should just follow ppl word that those stuff decrease latency and just do them i guess
