The latest update seems to have made my game more responsive than ever (with NoAsyncReads disabled, of course)
EDIT: Nope, I lied. It seems that if I do anything with the toggle, it seems to have an immediate noticeable effect on input latency (regardless of setting) until I restart the game.

But one more thing: I've also noticed that osu! tends to ignore my AMD driver's "flip queue size" setting (aka "max pre-rendered frames" on Nvidia) unless I set the in-game frame limiter to Vsync and then force-disable Vsync through the GPU. The game seems to run at the default of 3, so I'm forced to use the Vsync workaround in order to use anything lower. This behaviour does not occur when using the DX renderer in the fallback build.
(This setting also affects input latency, so perhaps forcing a pre-render queue of 1 if possible would be better for everyone)

EDIT: Flip queue size also seems to work properly in compatibility mode.

@Denro: are you sure you are on the latest build? I made a fix which should 99.9999999% fix this yesterday.

Yeah it´s fixed, at least for me. Got no more broken chains since yesterday and had them frequently before. Thank you.

Any word on this problem?

It's even worse now on cutting-edge (happens every few seconds and lasts over 10 seconds) but it also seems to happen in the latest stable as well. (much less often, around once per 5 minutes)

^I'm pretty sure the team has already been hard at work fixing lagspikes and stutters for the past while or so... I think the easiest way to help out is by taking screenshots of your frametime graph (Ctrl+F11) when it happens, and ing your performance.log file.

@Peppy, Seems like it is fixed now, thanks a lot. No more connection issues while playing the game!

Frame drops in CE

Log http://pastebin.com/nEnpKCdg

I can play for about 10 minutes Before my frame drops from Normal To 30-50 fps and heavy lag

@Nokui is this new behaviour?

Can't really say I took a few weeks off to stydy(since the 21/10/15). Updated and started playing today and this happened

It looks to be a common issue, if you are also experiencing very high u usage alongside (please check).

same, cant play more than 10 mins (80-100% u usage on osu)
got perfect pc, yesterday all was fine

I am getting high U usage, Guess I'll go to beta for a wile since it seems to be fine there.

btw got same lags in cuttingedge

Can confirm high U usage, also got it. Sometimes it's at 43% but most of the time it just spikes up to 97% (highest so far)
FPS lag issue fixed just then while I was typing this up, same goes to the U usage, thanks peppy.

I still feel worried about the latest cuttingedge...

The osu! overall lag issue haven't solved yet, and I made a video about this. You can see the bottom right, the lags become more serious at the end of gameplay

The lags exist in all mods: None, HR, DT...

Following the recent update the stuttering effect is much less noticeable even when outside of Compatibility Mode. It's still there, but osu is definitely playable.

http://pastebin.com/aQuHai4g

Here's praying for a full fix

We still have some ideas on how to fix the remaining stuttering! If you have the time, make sure to us on public slack. We need every single person who can still replicate it around for testing.

when i update to any version ( except fallback) i can only play song with less then 5 stars. how can i fix this?

You might have changed the range of the star difficulty you can see at options.

So since the new update you have the options called DEBUG
I ticked the first 2 and the last one and all my frame drops-cursor lag is gone
It did for my friend as well I hope that helps

it doesn't help. keep trial-and-erroring until you find the *one* option helping reduce lag. three options means nothing.

OK ok I will try my best

I'm no longer having the strange input lag behaviour with the NoAsyncReads toggle, but I now seem to be getting less input lag (with about 70% of the framerate) with ForceGLFlush enabled.

(also, I know this has been reported ages ago, but I'm still getting stutters when running DisplayFusion in the background... here's my performance.log if it helps)

With ForceGLFlush enabled, It seems the lags disappeared and FPS is looking good:3
Thanks for fix the bug.

Are you sure it actually helps? You need to test enabling and disabling several times, for long periods of playing to make sure it's actually the case.

I'm not sure about the lag spikes (the setting doesn't seem to affect whether I get them or not), but I've been playing around with ForceGLFlush for past little while, off and on in several different maps, and it does actually make a noticeable improvement in input latency when it's enabled.

How much of a difference are we talking? "maybe helped a bit" or "holy shit i can't live without this change!"?

I wouldn't exactly say it's life-changing, but I found myself having a lot easier time with aim-intensive maps with it enabled. In some cases, it's even the difference between ing and failing.

i just found a bug i think... the bonus sound on spinners are bugged, in spinner only maps (20s spinner f.ex.) they work but on maps with other hitsounds they aren't working for me, but only since this version of cuttingedge, just thought i'll throw this in here :3

So yeah, the spinnerbonus sound doesn't play anymore since the latest update which is b201511.2cuttingedge.

Weird thing is that the spinnerbonus sound does play in some maps though, for example Rubiks Cube. Although in most maps it indeed doesn't play anymore :S

Not an issue, but I wanted to report that Debug_ForceGLFlush fixed an issue that I've been having for months where osu! freezes up the GUI completely when it reaches 100% GPU utilization. I'm using wine-staging 1.7.54 on Arch Linux x86_64 kernel 4.2.6.201511122040-1-grsec
I meant to try it with the regular ARCH kernel to see what the GPU looked like during play (grsec disables /sys/kernel/debug for obvious reasons), but I've been too busy playing a bunch of new beatmaps

You guys have NO idea how bad I've been itching to play osu!. Thank you so very much for this debug feature.

Thanks for the . We've had a very small number of people mention improvements with flush enabled, so we are looking at making it a permanent (advanced) setting.

I found this issue in the latest cutting edge only.

already reported above?

OK after trying the New DeBugs options for a while the option called Debug_ForceGLFlush is the one that removes the cursor lag and also the Debug_GCLowLatency makes the cursor feel even smoother but ForceGLFlush does most of the job. :3

Debug_GCLowLatency cannot change the cursor.

Well it looked smoother cause I made the cursor smaller I guess..

what happened last update.

is 20151115.2cuttingedge official version?

-
on main menu, move point current play song not work. button is gone.

-
on song select menu, play sound less than 10%

-
play any mode will crash osu

We are aware of this. It will be fixed soon. For now you can change to Beta by holding Shift while opening osu!, select Beta and then repair osu!. This problem will be fixed soon.

Pretty weird though.

It is. Anyways, it should be fine already.

Hello, i got a problem today that was not there before a new update of Windows 10, before i had normal fps and could run it easily. Now, since that update, my fps dropped like a waterfall from like 1.6ms in beatmap song to 7-8 ms in beatmap song.This is happening in all 4 versions of osu which is odd and also this doesnt happen in any other game.

Here's some screenshots of the problem i have.

MY specs aren't the problem since i have i7 4720HQ and GTX960M All with updated drivers

Did you try restarting your computer since the update?

yes i did try that, first thing i did

ForceGLFlush and NoAsyncReads together have fixed my stutters, the stutters reappear if either of those options are unchecked, haven't gotten any more stutters since they are checked.

I don't know why a windows update would affect osu! in that way. If it's a constant frame time difference then something on your computer is taking up more U time since the update. Check for active processes for the source.

You don't see how a windows update could cause issues? What?

- After a windows update, many system services spend minutes or hours rebuilding indexes (.NET rebuilds its compilation cache, SearchIndexer will update etc.)
- New drivers may have been installed over existing better drivers. Check on them.

Almost certainly case #1 though.

have you checked both of these separately multiple times?

i did try that and doesnt change anything. Also i have everything updated.

NoAsyncReads has zero effect during gameplay. You must be doing something weird.

so you're saying i have no solution

I'm saying the windows update may be at fault, but you'll need to figure out the problem on your own. This is not the thread for it (since it is not an osu! issue).

i do think its an osu issue sicne this doesnt happne in nowhere else, ull keep you guys update.

OMG my frame is stuck at 240
I'm a mania player I can notice difference between 120/240 I used to play with 2000+ fps (i7 4790K / GTX980)
but now im capped at 240fps even when I select unlimited(while playing)
where is my unlimited fps option? please fix this quick

screenshot? proof?

peppy wrote: 73101g

screenshot? proof?

sorry i posted it on different forum section

I'm having this problem on stable(latest) version of osu

peppy wrote: 73101g

screenshot? proof?

^^^^^^^^^^^^^^
Here we have Unlimited frame option in Stable(Fallback) version


^^^^^^^^^^^^^
But as you see on Stable(Latest) version, there is only unlimited(while playing) there is no unlimited whatsoever
and that unlimited(while playing) option is broken that it capped at 240fps (even when Im playing the game)
I can tell this because when I play mania, notes are not smooth they go jittering

You're at the menu. This is intended behaviour.

peppy wrote: 73101g

You're at the menu. This is intended behaviour.

And when Im playing mania, bottom right only shows me my monitor Hz / ms only

There is no fps section

Also as I said, with the unlimited (while playing), the notes are not smooth as just unlimited frame

Logically, they should be exactly same

I'll try to make video in 60fps on youtube to show you what I'm talking about

That is correct behaviour. The frame rate is no longer displayed when on unlimited.

peppy wrote: 73101g

Okay i tried to make a video for this but it seems like when I record it with msi afterburner, it cant capture the problem

The fix is simple. Just put back Unlimited frame(not the while playing) option on the Stable(Lastest) version

When you do, i can test it out again to see if the problem fixed

Otherwise, I have to stick with the fallback version

notice the difference. its huge

^the framerate is no longer supposed to be shown on Unlimited. If the game is showing your monitor's Hz, it means the game is not limiting your frames. (the ms counter is better than fps at showing your gains anyways)
But if you're getting stutters during gameplay, that's a different issue entirely. Posting the performance.log file from your \osu!\Logs\ folder could help the devs iron things out.

(oh, and as a side note: @peppy maybe it'd be a good idea to rename the option, considering that it no longer shows FPS?)

I've rechecked them a few times and it seems as though my stutters are fixed from NoAsyncReads alone, not ForceGLFlush as I thought.

glFlush debug mode is forced on every startup. Please report back any changes to stutter frames you see (do they change from SwapBuffer to Draw? do they decrease?)

If you are having issues with the glFlush setting, you can either switch to beta, disable each startup or wait a few days until it is reverted to previous.

Hello so this is my last stand, since no one cares about the problem i have i'll ask one last time for help.If i don't get any solution im gonna give up on osu. Bye Bye 3 years of my life.

Use system restore or system refresh. Shutdown background apps etc.

Make a separate thread. This one is for cutting-edge issues.

I have a last Update my Gameplay 0.81ms, before has a 0.35ms. Please fix? :c (lastet Version from Cutting Edge is slower than older Version)

And new FPS Lag in Taiko, is unplayable. Mega stuttering

How can I disable GL Flush?

Thanks, is worked. Taiko is now playable.

"Code: [peppy] Force glFlush on for now (cutting-edge only)."

That glFlush makes my client having 4fps at most(seen it twice during few minutes) and impossible for me to even open options.
I really have no other information on it x_x

I used the shift menu on opening to switch the stable so I can play.

Apparently i just needed to dl a new osu!install.exe which is odd. Well everything is back to normal.

You can edit any settings manually through the config if you want to change them without using the client.

This happens not only in Cutting-Edge but also in the Stable Release Streams.

Can someone confirm this? I'm not sure if this belongs here or not. I was told by a member Team to post the issue here so I did..

Okay, while writing I actually found the error which is really strange, I will leave my original post here so I hope it helps other people or preventing the issue from happening again, not sure if it was something on my end but as I wrote it was doing the update, then nothing.

I copied over my profile config in the new install so I don't have to again and can switch to CE quick. As I wrote below that caused the error again. After looking into the config I deleted the LastVersionPermissionsFailed = b20150414.2 (or rather just the version number). After that Osu started perfectly fine, even updated and all fine now. I'm not sure why that line causes such a hard error, creating "dead processes" but I hope it will help.


Original Post.
I'm having some extremely weird error.
Since one update on Cutting Edge Osu! doesn't start at all.
That update seems to have went successful, but Osu! just didn't start.
It only created a dead process which refuses to be killed.


Fun fact, those don't even show up in the Windows10 Task Manager, not under details or processes.
A "taskkill /f /im osu!.exe" says that it successfully closed the processes but they remain in the process explorer. (using the PID directly doesn't help either)
The osu!.exe can't be deleted while those are active too.
Only a restart will get rid of them.

I tried installing Osu! again in another directory and run it there, working fine with Stable/Fallback branch.
Switching back to Cutting Edge will cause the same error.

I found out the GLFlush takes some fps away and also if you put a custom frame rate you will stop getting lags-freezes <--- at least that worked for me but only in cutting edge if I put a custom framerate in stable ( latest ) I will still get lags-freezes

Found a small problem with the scoreboards. On the first play of a song it won't show. Slightly annoying but restarting the song will do. Just wanted to give a heads up.

Shouldn't be. Probably your beatmap database is screwed. close osu!, go to your installation folder, move the "osu!.db" archive out of the folder and then open osu! again.

Thanks ill try that.

Pressing F10 in a rapid motion turns all volume sliders slowly up (if your cursor is above the sliders), opens up the chat or extended chat or goes to beatmaps and posts some hex code repeatetly (example: f80e) until it can't post anymore all this while the fps goes to 0 and then osu can't be controlled anymore. Going on the desktop and back into the game fixes this or pressing ESC a few times.

System Config: Gaming laptop with duel graphics. (Intel 4600 & 970M with latest drivers)

I ran both configs:

Notice: I have 144hz monitor connected through displayport.

I run it with borderless, but I tried with Full screen mode in Beta version, and it seems to add more latency , as a result, I moved back to the CE.

I will provide a video if you are curious how it looks like.

That sounds like optimus hardware. Am I correct in believing this?

I forcefully set it up so that osu runs only on High-performance nVidia graphic processor.

I am pretty sure osu does not rely on intel graphics anymore, but I am still not 100% sure about this problem.

optimus is known to have issues with gl in general. we're working on a solution, but for the time being the answer is to run on intel (and somehow fix your crashes)

I have read your vlogs about optimus things too (of course nVidia isn't cooperating this and that)

I'll follow your suggestion and if you need to test anything on my setup, please let me know.

Thanks.

I'm having a fairly significant input latency increase when "Detect performance issues" is enabled... It's causing my game to be even less responsive than even the Fallback build.

Detect performance issues doesn't add any overhead.

...well, I just did a little more testing (because I really don't think I'm going crazy), and it seems that I get considerably less latency in-game if I go back and toggle anything in the options menu after the game's startup. Even things that shouldn't have anything to do with performance at all, like the chat font. (or I am going crazy, I dunno. But I thought it was "Detect performance issues" because it was the first thing I unchecked after struggling to play for nearly an hour)

Performance log please (make a note of what time you open the options menu).
