osu!

osu! builds from the Lazer (new osu! client) release stream.


osu!lazer is a new official osu! client made from scratch. Curently it lacks many features found in Stable builds, is a little buggy and its performance has not been optimized, so it is not a suitable replacement for Stable client yet.

On the other hand, Lazer exhibits many graphical innovations and is built over a more consistent base, using the new osu!framework which is based on .NET Framwork 4.6.1. On Wine, many graphical glitches related to GDI+ and CJK fonts are no present: the game renders perfectly every detail so no workarounds are required for them.

Test Results

Old test results
The test results for this version are very old, and as such they may not represent the current state of Wine. Please consider submitting a new test report.
Selected Test Results

What works

  • Main menu: works perfectly.
  • Options menu: nearly all its options work, except described on "what does not work".
  • Selection menu: all its implemented options work.
  • Gameplay: all game modes work.
  • CJK Fonts: works!.
  • Drag and drop: importing beatmaps through drag and drop works.


What does not

  • Options menu:


    • Raw Input (don't even try to enable this, you will lose total control of mouse, including clicks).
  • Fullscreen does not work properly.


Workarounds

Installing .NET Framwork 4.6.1 to get the game running.

Installing a low latency Linux kernel to fix:

  • Severe audio latency (switching audio driver to ALSA also may help).
  • Game freezing when selecting songs too fast.

The game itself needs to be installed decompressing the "osulazer-full.nupkg because the installer requires non-administrator privileges.

What was not tested

  • Editor: not properly tested.
  • osu!direct: not tested because it requires osu!support.

Hardware tested

Graphics:

  • GPU: AMD
  • Driver: open source

HowTo / Notes

Troubleshooting

Last update: 2020-12-31.


Arch Linux specific:

  • osu! doesn't render anything on screen and exits with some X server error message: install lib32-libxcomposite package:

    $ sudo pacman -S lib32-libxcomposite
  • osu! can't connect to internet: install lib32-gnutls package:

    $ sudo pacman -S lib32-gnutls

Japanese characters no displaying correctly: install MS Meiryo font:

$ env WINEPREFIX=$HOME/.wineosu winetricks meiryo

Set language to Japanese to correctly display all kanjis.

This font doesn't include Korean glyphs.


Options menu symbols and audio controls are missing: install GDI+:

$ env WINEPREFIX=$HOME/.wineosu winetricks gdiplus

GDI+ installer is a ~538MB file. If your internet connection is slow or limited, consider instead taking a copy of gdiplus.dll from a Windows 7 installation and copying it to your Wine prefix, and then add manually a Native override for gdiplus.

Open winecfg:

$ env WINEPREFIX=$HOME/.wineosu winecfg

Go to Libraries tab, add gdiplus and set it to Native Then Builtin. Close all dialogs by clicking OK.


Some unusual image formats are not shown when using native GDI+: install windowscodecs through winetricks:

$ env WINEPREFIX=$HOME/.wineosu winetricks windowscodecs

Note: this workaround may break screenshots and interfere with other windows applications installed on the osu! wineprefix when trying to save files. If you need to disable it:

$ env WINEPREFIX=$HOME/.wineosu winecfg

Go to Libraries tab, find windowscodecs and set it to Builtin (Wine). Close all dialogs by clicking OK.


Audio latency, sound distortion or no audio at all: first try setting PULSE_LATENCY_MSEC environment variable to "40" before running osu!:

$ env PULSE_LATENCY_MSEC=40 WINEPREFIX=$HOME/.wineosu wine 'osu!/osu!.exe'

Other values could be tested in order to get lower latency or fix sound distortion/crackling.

Enabling "Audio compatibility mode" in the osu!'s options menu will switch to legacy DirectSound-based audio engine (osu! is now using WASAPI). It can solve some problems but has higher latency and some audio stuttering.


Also check out The Poon's guide and Franc[e]sco's guide.


Frame limiter is permanently locked at 60 fps:

Disable vertical sync by setting vblank_mode environment variable to "0 " before running osu!:

$ env vblank_mode=0 WINEPREFIX=$HOME/.wineosu wine 'osu!/osu!.exe'

This way osu! will not be able to enable VSync at runtime.


Video latency

Desktop environments usually draw on screen through a compositor than enable fancy window effects. This may cause lag that you can feel when moving the cursor.

Note: you will prefer to run osu! under X.org since Wayland is not fully supported by most window managers.


  • GNOME 3 (Mutter): it should disable it automatically when running at borderless/fullscreen. If you're running on windowed mode or have many monitors, compositing may remain enabled unless osu! window fills all the screen output area.


  • KDE Plasma 5 (KWin): press Ctrl+Alt+F12 to disable/enable compositing.You can also add a window rule to block compositing when osu! starts and re-enable when it close.


  • Xfce 4 (Xfwm):

    Disable compositing:

    $ xfconf-query -c xfwm4 -p /general/use_compositing -s false

    Re-enable compositing:

    $ xfconf-query -c xfwm4 -p /general/use_compositing -s true



Other known problems:

  • My system is frozen!: if osu! freezes and you lose the control of your system, press Ctrl+Alt+F2 (to enter to a tty) login and enter the following to force closing osu!:
    $ pkill osu

    Press Ctrl+Alt+F1 (or Ctrl+Alt+F7 on some systems) to return to your desktop environment.


  • I ran osu but my cpu usage is at 100% and nothing happens: same as frozen system. Open a terminal and run:
    $ pkill osu

    Wait 10 seconds and try again.


  • Alt+tab doesn't work when Fullscreen is enabled: if you can't use Alt+Tab hotkey, disable Fullscreen mode inside osu!.


  • I can't switch to Windowed mode from Fullscreen/Borderless/Letterbox: close the game. Open osu!.«your_user_name».cfg in the osu! folder, and edit the next fields:
    Fullscreen = 0
    Letterboxing = 0
    Width = 800
    Height = 600
