I've been trying to find the solution for my problem, seriously. If this was discussed somewhere - I didn't find it. Sorry. ;)

Anyway, here's my problem. As soon as I double click osu!, it's starting picture appears (as usual), but then my mouse disappears. Well, actually it's like the whole game window became transparent and I can't see anything. I can hear the music, I can hear the sounds of pressing buttons, I can play beatmaps normally. But all I see - is my desktop! No sliders, no backgrounds, no hitcircles. Not even a black screen. Nothing. :o
I tried reinstalling osu!, everything was okay until it started loading all songs I have got thus far. It has crashed (Idk why), and then this bug happened again.

Can you help me with this? :cry:

UPDATE: Thank you guys, I'm tired of waiting, so I've just deleted .cfg file. Obviously, it helped me, not counting reseted settings though C:
Thanks again.

i have experience gameplay lag after i update(update that contains replay speed of .5x). and memory usage is 200+ at initial instead of 100+mb.
um...I can say that is normal when you play it turns like that too o3o

I guess I'll have to just live with the lag. I have 8gbs of RAM and it gets nowhere close to maxing out at any point in osu!.
Lower your resolution and play windowed I manage to replicate that kind of problem but playing on windowed mode with 800x600 solved mine :)

My Osu! starts lagging as soon as there are sliders in the beatmap but as long as there are only hitcircles it works perfectly fine. Also the menu and the audio are not lagging at all. I didn't have any problems with Osu! around 3 days ago but I updated it now so could that be the reason for my problems??
I restarted my laptop afterwards and didn't change any settings at all before the lags started. It's on DirectX with 120fps and Low-End-PC.
I tried changing to OpenGL and a lower fps rate but that didn't help either :(

Ever since the last update to Osu! my game has been getting long sputters of lag, and for the life of me I cannot seem to find out why. I have the same problem, but it starts in the menu and is present throughout my game, regardless of sliders or song selections or the options menu, it lags on them all. My settings have been perfectly fine up until now, so that leads me to believe it is something added to the game.

Whenever I do multiplayer on here my mouse seizes to move how I want it to. Like if I try to move it straight left, it might go up and to the right. The input is just uncontrollable. Nothing wrong with my Internet, and my mouse has never done this outside of this game.

I found a program wich optimizes the computer to play games. It also closes useless processes to reduce CPU usage, among other things.

More info and download here. Note that you will need an account to use it.

Gamebooster is pretty much helpful but sometimes not required
and btw a little note don't defrag the osu directory using gamebooster

what can be the cause for this?
SPOILER
it happens when maximizing the gamewindow or playing maps in osu! standard mode.
taiko, CtB and mania are fine.

the cause might be very poor Graphics, ram and cpu since this is on a Asus VivoTab smart me400c which runs full x86 win8
its a intel atom 1,8 Ghz (might be dualcore) and 2gb RAM, it says that is has a maximum of 725mb grafics ram and i dont know the coreclock

i'd like o know what's wrong if it isnt cause of the performance

Posted two methods that I discovered that will improve performance in your game. You can find these in the OP.

Edit: I should note that I don't think this thread is regularly checked for new issues. If your issue isn't tended to within a couple days of posting here contact a member of the support team. You don't need to post your issue here and may post in a separate thread. It is not so easy to troubleshoot such issues in a large thread.

Thought this'd be the best place to hunt for help.

After playing osu! for a few weeks, I tried my hand at the beatmap editor. After trying .mp4 files into osu!, I converted the file to .mp3 and began mapping. Being horribly inexperienced, I gave up after a few hours and deleted the map, and took a break from osu! for a bit. However, when I came back (this is about the start of July, maybe a few days after), I found immense visual lag on both the menus and game. Turning off all the special effects and turning on the FPS counter, I saw a 10-20 FPS drop in the songs, and up to a 50 or 60 frame drop at spinners. So I ran windows update, updated Avast, updated Java, made sure DirectX was updated as much as possible, ran osu updater multiple times, ran defrags and virus checks, and uninstalled and reinstalled.

My osu build is b20130626, and I'm using Microsoft Windows XP Service Pack 3 Home Edition Version 2002. I have an AMD Athlon 64 X2 Dual Core Processor 3800+, 2 GHz processor speed. But osu ran perfectly before this incident, so I don't know if the physical specs are the issue.

I'm getting random slowdown on beatmaps at the start and at random intervals during. On a i7-4770k and a gtx 770, I have it limited to my monitor refresh rate, which is 144fps. I have also tried to remove frame limiting but that did not help as well, even tho it's always at 2500+ fps it's still slowing down at times.

This post is going to be messy. I have limited knowledge on this. Some of what I say is based on observed opinion.

You should try switching to OpenGl if you're having performance issues. Updating your drivers may help as well. There are probably performance related settings that are reducing stability of the frames. osu! may not be receiving enough resources to run for example. It wont help if you're using the highest resolution setting for your super wide screen with HD osu! textures. You can try using a lower resolution to stabilize your frame rate.

You may be experiencing input lag. Movement of the cursor requires frames to reflect movement. Large changes to the frames being processed can have an effect on how accurately you can move the cursor. You should try to reduce the amount of frames the game drops/adds during spikes. You can try the game's frame limiter. You can use a custom value by editing the config file (maxes at 500). If that doesn't help stabilize your spikes, you could try a program that reduces frames.

I'm not really knowledgeable about refresh rates of monitors. Sorry!

@rip Could you explain what you mean by slow downs?

It's really hard to explain, but I would experience slowdowns on the game, kinda of like when you play something in 60-144fps its SUPER SMOOTH, and when it suddenly drops to 20-30fps it feel REALLY SLOW. That kind of slowdown, but I was still at 144fps all the time.

After doing some testing I can now confirm that I have found a fix to this issue. I'm on Win 7 and I managed to fix these random slowdown by disabling Aero, now it's always super smooth. Seems like it was causing problems, how :?: I have no idea but it works. :lol:

haha i awhile ago i had this sudden delay on my cursor and i was raging all over =3=ll, but then after a day of idiotically flipping tables, i finally found out that i was on vertical sync. So it wouldnt hurt to try pressing F7 if there was like a delay for no apparent reason. idk, change it to like unlimited or something. Food for thought xP 8-)

you could try to disable the video, storyboard and beatmap skin? Also in options you can try disabling some of the settings for details settings.

Since last Update i've been getting a small delay at the start of some songs, it's not that big, but if the Notes start at the same time the music kicks in (like with no break or spinner before the first note of the song) it can be annoying.
it doesn't happen all the time, and it's accompanied by a "click" type sound (I can hear with my headphones on very high vol) when it does right at the start.

So, i basically removed the major lag from my PC by using OpenGL. There are still some minor lag, but they are tolerable. I highly recommend you to switch to OpenGL first if you experience any huge lag.


I'm still waiting for that OpenGL osu! peppy ;)

If you've done all you can on the software side and nothing improves, and you're serious about wanting to play osu! without lag, you will have to seriously consider upgrading your hardware - at least to the level where it can play 2010 and newer 3D games without lag - and this means a discrete/dedicated graphics processor / GPU / videocard for desktops and certain laptops, and better laptops with more powerful graphics hardware for the rest.

Lasi i recall, a barebones desktop hardware package (4-core CPU, 4 GB DDR2 and motherboard with AT LEAST ONE PCI-Express x16 slot i.e. graphics card slot) will run at least $200, and a (PCI-Express, of course) graphics card will run anywhere from $75-150 or more. And please, don't be a cheapskate, get a Power Supply Unit (PSU) that is AT LEAST 500 Watts or more (and should have most, if not all the needed power connectors).

The rest are irrelevant with MAYBE the exception of Serial ATA standard hard disk drives, or if you intend to go bulls to the walls, an SSD for your Windows OS + performance emphasis programs e.g. osu! and the rest on some massive capacity SATA drive. (While you can still use your good old PATA/IDE hard drive, it probably won't be as fast in terms of program / file / song / beatmap loading times.

Of course, all of this assumes you can build your own PC and have the OS installation disc, drivers, etc.

Having a UPS is optional (maybe if your power company is a reliable one) but if you do, get one that is rated MORE than your PSU's max output + all vital peripherals' wattages. Just because the UPS says 600VA does NOT mean it can support 600 watts (it doesn't) - go look for the rated max wattage output of the UPS in battery power mode. I personally run my tower, modem, router and monitors on a 1200 watt UPS unit, and have been laughing off brownouts, power outages and power glitches/spikes/drops ever since.

Actually, any laptop featuring 3rd and 4th generation of Intel I-series should be able to run osu! smoothly since they use HD4000 / HD4500 (or something like that) which is good enough to run osu! decently, same applies for PC, if you don't play any other games than osu!, I'd more recommend buying motherboard with support for Intel's Integrated GPU within CPU, possibly HD4000, and it will work like charm.

Anything related to laptops
I suggest switching to windows classic(no theme), resolution 800x600, apply gamebooster 3, close any background programs running(torrents, setups, browsers, IRC, scheduled scans and updates, firewalls[depends]..etc. ]

Another thing is using framerate 60/120 don't use unlimited since the last time I used speedfan with the unlimited on laptop actually overheats
Higher the fps higher the processing you can use customframerate=60 , MyPCSucks= 1 in the [userhere].cfg

When downloading beatmaps use this method
close osu, download new beatmaps and drag them to the songs folder so once you open up osu its processing

Q.Lag Persist when laptop heats up?
A.Reboot/Restart PC/laptop

Q.Screwed up hitcircles and sliders?
A. Reboot/Restart PC/laptop

Q .Updated Osu?

I always have a HUGE lag spike when the online scoreboard appears (after loading) when I'm already playing the map..
My only workaround is to switch to a local one.. Or sometimes I'm lucky and scoreboard loads fast, before notes appear
Can some optimization be made on this?

I have the 3rd problem in the start of the topic.
Basically, whenever I'm playing, it just freezes lightly and I miss a note for no reason.
I can't play like this and I've tried closing ALL background processes, all USB ports removed, but it still happens. What the hell is going on?

I'm getting constant lag spikes at certain moments in certain Beatmaps I play. I did check the front page and skimmed through a few pages to see if there was a resolve for me, but to no avail. Furthermore, my mouse seems to want to fall behind at certain points where it begins to have a lag and I have to pull it ahead of the song.

I used 60 FPS (Vsync) and have tried other FPS limits, but nothing has worked. I use DirectX, and touching OpenGL does not solve a single thing. I also have turned off many of the features already, so I shouldn't have anything CPU intensive. My CPU usage while playing Osu! is at 5% if that's worth anything, so it doesn't seem like it's even close to grinding.

I have 12GB of Ram and a 3.6GHz i7 Core, so I'm a little confused with what's going on. The only other thing I could possibly think it is, is the fact I have an integrated graphics card, however it's a $300 motherboard made by ASUS so I imagine it could easily withstand Osu! (As it has withstood harsher games).

Aaaaye! I recently switched from windows 8.1 to windows 7 due to excessive bloatware that was slowing my computer down. But now I am experiencing extreme performance drops in osu! when i am running it on the same hardware, just different OS. Any halp would be appreciated.


I have done things such as limit to 60 fps and run it in windowed and full screen mode. I have also turned off all graphical settings examples being hit lighting and snaking sliders. I am currently trying to re install the game to see if that helps.

Same thing is happening, but for me it also has everything freeze and loop the audio nonstop for a few seconds then goes back to normal. I tried everything and what i noticed while looking at the processes during the audio loop and freeze, the "CPU" number would turn from 03 to 00.

Wut is happening T_T

I started experiencing really heavy lags while playing recently. To the point where game starts resembling some slideshow - playing insanes is VERY fun now. The fun thing is that FPS counter shows something in 120~80 range.
I can't be really sure, but it seems this all started right after OSU! updated a few days ago. Not to mention that the FPS counter itself somehow turned on automatically after that update.

Lags appear occasionaly, last for a while, then disappear. As I wrote that post, for example, at the beginning osu! was lagging furiously, but now FPS counter shows 600-900 fps, and lags disappeared completely, and the game's running VERY smoothly.
Also, everything seems to be a little better if I close Opera and other programs, but - they're not eating any resources except memory (and only 1GB is consumed, checked via taskman), and everything worked just fine even with much more heavy background load less then two weeks ago.

I didn't change/update/install anything into the system for some time before/after lags began, so that can't be the reason. Also tried limiting the framerate to 60/low end PC modes - no luck, no changes at all.

Sys Specs:

Win XP SP2
Core2Duo E2200
NV Geforce 8600GT
2GB Ram

I understand that issue might be because of browser being a bitch and overloading the system while opened on some pages, which together with the hellish air temperature (>30 celsium ATM) would cause something throttle-like in the processor, but temperature is below 45 cels. on CPU and about 60 on GPU (according to everest, BIOS shows something about 30 for CPU), so I don't really think this is the case.

P.S. Digged into the matter deeper while writing this. Lags certainly seem to appear when I have Opera opened on some pages w/heavy animation, because it's eating up the processor, but they appear as well when it is minimized and CPU usage, aside from OSU, is 0. And then again, everything worked just fine until recently, even with the animated pages in the background. Also, seeing lags while FPS shows 350+ is amusing.

P.P.S. While I'm at it, two other bugs, rather minor compared to that one:
1) OpenGL mode seems broken - OSU! would flash with transparency roughly once a second, hence it's nearly impossible to play.
2) While in Multiplayer, when everyone is ready to play, if you hit F5 and, while you're updating, host will start the game, then you'll be back to the multiplayer screen and everyone else would just stall. Encountered this only once, don't know if it's repeatable.

UPD: aaaand osu just crashed while in multiplayer. It seems something is broken after all.
Believe it or not, I play with the same pc, but with a NVIDIA GT210, and it goes pretty fast. Only change your GPU and you can play ANY game. Really. ANY

I have same problem here, I played a beatmap (no video) I get above 1.000 fps. BUT when I play a beatmap with a video, I only get 130 fps and sometimes dropped to 70 or 30 fps. is there someway how to fix it?

My game on my new pc has unbearable lag. This desktop has good specs and kind run most games on the highest settings.
The lag is constant; it occurs even in the menu at startup. It will freak out for a few moments, smooth, freak out, smooth, etc.
I can't fix it. I have tried different frame limits, openGL, vsync, updating it, restarting my computer, and even reinstalling with both installers. Nothing seems to work. Some Specs:
Processor: Intel(R) Core(TM) i5-4460 CPU @ 3.20Hz 3.20 GHz
RAM: 12.0 GB
System Type: 64-Operating System, x64-based processor

Hello sir, i assume this game is Only take up a single core of processor, and not optimized for multi Core Processor.

i alerdy run a benchmark with
Processor : Intel Core 2 Duo E 6500 Vs Amd Athlon II X3 455 ( both i Overclocked to 3.5 Ghz )
GPU : Nvidia GT 440 1 GB DDR 5
Ram : 4GB

The result was
The Dual Core Get Higher FPS @1100 - 1200 in game
while the athlon II x3 455 triple core processor only have FPS Around 800-1000 in Game

so i hope this game will well optimized in future for multi core processor so it can take advantages from the multicore cpu horsepower. also make fps drop nearly impossible :) :idea:
