Visual lag during gameplay #8271

Closed cyrdoctus closed 4 years ago

cyrdoctus commented 4 years ago

I have installed the osu!laser recently and I have encountered quite bad performance, I know that it is a developer version, but after seeing other people play with it and don't have the same issue seemed weir. The issue is about the circles spawning and timing of circles, it is way off and seems very jittery even when the fps monitor is giving way over 800 FPS and under 1 ms latency. the notes just seem off sync, even the circle reacting visually to the click is off, but the press is immediately registered. So far I have tried reinstalling drivers from gaming one to studio one, and back as well as reinstalling the game. I have tried the android version and I haven't encountered the same issue at all.

So my question is, is it the current version issue or is it an issue somewhere else. So far I have been using the standard osu launcher but got interested in this one, that's why it felt weird when I have encountered this performance issue.

System specs: i7 5820k 32 GB ram RTX 2080 Ti

Game settings: Multicore (Tried single-core and got everything laggy), Framerate unlimited (also tried every other option)

Can confirm, recorded a side by side frame comparison of stable and lazer https://www.youtube.com/watch?v=Trz1HWxgdQs This started to happen a few releases before

Running 2020.312.0

Running 2020.312.0

If you know it started happening "a few releases ago" then please take the time to at least go back through each release and confirm this. You can download all old builds from the releases page.

What your video is showing looks like an audio library or driver issue. If you have another audio device available please try switching to it.

I don't notice the related issue in releases previous the culprit 2019.1128.0 release. It would be helpful if @cyrdoctus can confirm this.

Can confirm tested all releases past 2019.1113.0 and significant lag or jitteriness around circles approaching was not prominent until version 2019.1128.0, I have even tested versions 2019.930.0 and 2019.1011.0 and those had only minor lag as it seemed only the sound was off. My test methodology was to run map Yoru Naku Usagi wa Yume o Miru (other maps ended on the same results when tried) on auto and highest difficulty and then tested it on hard difficulty manual, where even cursor click movement was off. To test that this was not truly only sound off, I have run every test past version 2020.208.0 without any sound, which came to the same jitteriness in circles approaching, to verify each 5th run I switched to normal osu launcher (that one run buttery smooth). Also, the lags lowered after version 2020.225.0 or at least they seemed slightly better and that with or without sound, Hopefully, this will be helpful. @peppy @oSumAtrIX

Details of test setup: Monitor LG 32GK850F 144Hz 1ms (free-sync off, 1ms motion blur reduction on) GPU RTX 2080 Ti i7 5820K 32GB 3200MHz Ram Keyboard and mouse both have 1000Hz sampling rate (Razer diamondback, Razer Blackwidow elite) Autio was directly out of motherboard's soundcard to headphones Sony MDR-100AAP Game setup: Framerate set to twice of the monitors refresh rate. (no difference between different settings) Also, the input set on raw and game resolution 2560*1440 Fullscreen

Thanks for providing the version bisect. Could you please open the frame time overlay (Ctrl+F11 until you see graphs) and confirm there are spikes on the audio thread when this occurs?

If so, this is a duplicate of https://github.com/ppy/osu/issues/8185 and can be closed. It matches in terms of commits.

@peppy Yes it can be closed, after recent update no more lag present, lag spikes at audio are gone.
