The osu! Advantage - The Truth About Latency

[@no_aveil]

my brain has too much latency

[@Jaymusta]

Why does this comment go SO HARD LOL

[@Boxsnake]

I can confidently say that obtaining lower latency through pc upgrades, wired headphones, and better overall hardware definitely helped to a great capacity on my improvement and consistency in the game. ultimately I still believe that whatever you get used to and consistently play through in long periods of time is what and how you will improve upon and these should just be looked as optimizations to potential improvement.

[@Jaymusta]

I agree 100%!

[@BadWallaby]

I really enjoy these in depth looks at things that usually come up in a twitch chat haha

Hey thanks!

Really high quality, definitely subbing.

Thank you!

Fire editing! I respect the time that takes (and thank you for the informative video)

[@Jaymusta]

Yo thanks man!

[@mesho8575]

nice one as always on a side note: I really want to see a video that literally measures the duration between a tablet motion and actually moving on monitor, then compare between "optimal" vs "unlimited" to observe if actual difference or just placebo people do that in other games like overwatch but for osu I've never seen anyone trying this out

[@Jaymusta]

This would be super interesting to see! It would be a cool way of seeing how overall system latency might be affected by toggling that setting. Hypothetically, I could see any differences between the 2 settings being more measurable with higher end peripherals. Since it would be a test of end-to-end latency differences between two in-game settings. It'd be like how some people start noticing a difference between 1,000hz and 8,000hz mice on setups with 360hz+ monitors

[@chaniibak7702]

It’s an actual difference. My computer usually gets .15ms when playing, for reference. I tried the 960fps cap and was able to feel the delay in the cursor. I’ll try it again tomorrow and update

[@kaimuu]

@@chaniibak7702 the furthest I've seen anyone go with feeling the difference between polling values and their latency was Willy with being able to notice the difference up to 480hz consistently and barely missing 720hz by one (done in lazer's visual latency test). It's highly unlikely that anything above 1000hz polling will not be noticeable especially the difference from 1000fps to like 2000fps or 3000fps since the actual latency difference gets exponentially smaller. 1000fps vs 5000fps might be a big enough step for it to maybe be noticeable but at that point you're still comparing very small amounts of latency to another. Basically yes the difference is there but it's so small that in basically every case going above 1000hz is almost entirely useless since the only thing it will bring is potential lagspikes due to your system being at its limit all the time. Would really be interested if you could also try the latency certifier and send your results.

[@RieMUisthegoaT]

I've never saw anyone make a video about this but I've heard of this from the moment I started osu! back in 2016. It should be quite known that unlimited makes a huge difference, also I'm pretty sure there's a tool in lazer that compares optimal to unlimited to 60fps etc..

[@Jaymusta]

@@RieMUisthegoaT It especially makes that difference in osu!stable since the game’s ability to read your input is directly tied to fps. As for that tool in osu!lazer, it mainly tests how much you can tell the difference between different fps visually. But it doesn’t help with how that ties into how it feels while playing the game. (You just sit there and pick which half of the screen looks smoother to you)

[@kisalli1]

i have 2 setups, one with a 60hz tv monitor and one with a 144hz monitor and i just adjust the offset like 30ms and i'm fine also reading ar9 is way harder with 60hz

[@Jaymusta]

Dude I could not play ar10 on the laptop I started playing the game on- it ran 60hz and had terrible blacklight levels When I switched to 144hz on desktop, it became more doable. 240hz helped me read ar10+ better

[@gfujvvh]

even when i played on a rlly bad setup i don’t think i ever experienced actual latency before idk

[@Jaymusta]

It can be really hard to tell sometimes, especially if you don't know what to look for between setups

[@chaniibak7702]

That’s just you.

[@MightyBreedable]

i strongly believe that mrekk has like negative human latency thats why he is so good

there ain't no way they already made a osu! HOW meme with the booba o

Made by yours truly 😉

[@guardianguy6986]

Human latency is why I started using capacitive keypads within my first month of playing

[@cursedtosufferGRIMM]

To me, for some reason, all my hitsounds are late, but only when I play, not when I watch a replay, so whenever I hear that I hit perfectly in sync with the music I am always a bit early.

[@Jaymusta]

Interesting, is it like this across multiple skins? There’s a chance the delay could be coming from your hitsound files- I can suggest watching this video to help check/fix them (specifically around 13min into the vid): kzbin.info/www/bejne/j6vGqnqQZs95l8k&si=-sNyztxVsD9_rJ4P

[@Snioflake]

the delay is likely not coming from hitsound files, the delay is also not in your head. the game just has a latency of at the very least 20ms as a result of the audio api it's using. the average user ends up getting ~45ms of delay because the game adds on a ton of input delay. both stable and lazer suffer from this, lazer usually adds another 5ms. most standard players don't seem to realize this because osu is one of the few rhythm games that you can actually still kind of play with terrible delay. mania players do realize this which is why most play without hitsounds and -50ms delay. If you wanna find out your actual delay, record your headphone output and mouse clicks (not keyboard) on a test map then look at the difference between clicks and hitsounds in audacity. (as for fixing the delay, faster APIs are available but those alone wouldn't be enough and it has been an open framework issue on github since 2017 with no prospect of this ever getting changed)

[@PapaJuan]

I got down to .08ms on osu! standard. No stuttering, and it felt really nice. Now I play on Lazer where it is locked to 1ms. Honestly feels super close. The cursor felt a little 'lighter' on stable, but that was about it.

[@PapaJuan]

The main thing that really bothers me is that my tablet is only 133hz, so it's annoying doing fast movements.

[@Jaymusta]

@@PapaJuan Dude I swear if someone could fork the Hyku tablet project and sell an updated one I’d be SOLD (I lost the one I ordered 2 years ago) It polled at 600hz and felt so good to play on. The Lazer experience seems to vary between people. From Azer having performance issues, to quite a few more people appearing to need at least -15 global offset (including me), it is so close to being good enough for me to switch over.

[@PapaJuan]

@@Jaymusta weird. I did notice hitsounds were a little off, but I don't play the game much. There was a setting somewhere where you could modify hitsound separation, and I just turned that all the way down.

[@Jaymusta]

@@PapaJuan I did see someone else mention that, I’ll have to try it out next time I play Lazer.

[@rudnhed8djhrhdhdrhhfhf34]

Too much latency means your gpu cant rander fast enough that the game is damanding so yea latency does matter for a game like osu

[@Jaymusta]

There’s also other parts of the picture like the performance of peripherals that can affect end-to-end latency between the user and the game But yeah, I’d argue that latency directly affects more of the playerbase in osu! vs other games due to how it’s a game based on rhythm sense and music

[@rudnhed8djhrhdhdrhhfhf34]

good luck hitting a single note with 8+ ms delay@@Jaymusta
