Bug ID: 45072 Summary: Wine 3.6 causes 100% CPU use in MikuMikuDance Product: Wine Version: 3.6 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown Assignee: wine-bugs@winehq.org Reporter: myjunkmail311006@gmail.com Distribution: ---

In wine-3.6 (Ubuntu 3.6-1), running MikuMikuDance, an animation program, causes MikuMikuDance to stay at 100% CPU use (one CPU core).

In wine-3.0 (Ubuntu 3.0-1ubuntu1), it's at 21% CPU use under the same conditions, which is with nothing loaded and not rendering any frames using the 'save power' mode under View menu. with 'save power' mode turned off, it's at 31% CPU while rendering the coordinate axes at 58 fps.

In Wine 2.18, it used the same or less CPU as in 3.0.

I know the guidelines say to run a regression test but I don't think I could compile wine successfully; I'm using the Ubuntu 18.04 stable and development packages.

This happens with a default Wine install, which is enough to run 32-bit MMD without the addon MikuMikuEffect. (Installing a specific version of Visual C++ 2008 may be necessary to get 64-bit MMD to run at all.)

(With my CPUs set to lowest frequency, MMD goes to 50% CPU in 'top' with Wine 3.0. With Wine 3.6, MMD goes from 60~100% CPU at maximum frequency to 100~115% CPU at 1/3 frequency.)

--- Comment #1 from Misaki myjunkmail311006@gmail.com --- MMD can be downloaded at http://www.geocities.jp/higuchuu4/index_e.htm

The WineHQ database has test results that explain how to make MMD work better, like getting the interface to show up.

--- Comment #3 from Fabian Maurer dark.shadow4@web.de --- Bisected it to

commit dd0ea0a61463db83c647a9367ca61e2b69a98eb3 (refs/bisect/bad) Author: Henri Verbeet hverbeet@codeweavers.com Date: Fri Feb 16 09:39:08 2018 +0330

wined3d: Enable the multi-threaded command stream by default.

However, this doesn't really help, since it's not a regression in that sense.

...

CSMT is controlled through the registry key HKCU/Software/Wine/Direct3D/csmt, which is a DWORD value. Setting the key to 0 will disable the feature, while setting it to 1 will enable the feature.

Disabling csmt returns the CPU usage to normal levels with wine-3.7.

--- Comment #4 from joaopa jeremielapuree@yahoo.fr --- CSMT is enabled by default. What is the status of this bug with current wine (3.20)?

Can an administrator close this bug at the URL place?

--- Comment #6 from Fabian Maurer dark.shadow4@web.de --- @joaopa That looks a lot like an illegal re-upload.

The official download is https://sites.google.com/view/evpvp/ MikuMikuDance (DirectX9 Ver.)

I can confirm the issue for this download in wine-4.21.

--- Comment #7 from joaopa jeremielapuree@yahoo.fr --- Does the bug still occur with wine-8.7? I can not test by myself since I do not know how to use this software.

--- Comment #8 from Fabian Maurer dark.shadow4@web.de --- Yes, still present as of wine-8.7. To test, just run the software, it will fully use one cpu core. Then try it with WINE_D3D_CONFIG=csmt=0 to work around the issue.
