Looks like the Wine developers consider the Multi-threaded command stream for Direct3D good enough now, as it's in Wine 2.6.

For those that don't know what the 'Multi-threaded command stream' is or does, it should hopefully allow better performance in certain games ran through Wine on Linux.

Wine 2.6 highlights:
  • Multi-threaded command stream in Direct3D.
  • More Shader Model 5 instructions.
  • More support for 3D textures.
  • Better font transformations in DirectWrite.


They fixed 25 bugs in this release which includes fixing issues in games like Neverwinter Online, Rogue Operatives, The Solus Project and more.

They also included a fix that multiple games and applications needed, to quote the release log:
QuoteMultiple games need msvcr110.dll.?_Id@_CurrentScheduler@details@Concurrency@@SAIXZ (World of Tanks v0.9.15, Bethesda.net Launcher, Train Fever)

Pretty great release, congratulations to the Wine developers for their constant effort.

If you want to enable CSMT (Multi-threaded command stream), you need to do it via regedit, so launch it with Wine first:
wine regedit
Then scroll through to Direct3D like so:

Then, you need to rename it to "csmt" and make sure the value is set to 1. Article taken from GamingOnLinux.com.

This will be an interesting weekend, can't wait to test out some games. Cheers to all the ones involved.

Yeah, I know. But the performance advantage of gallium-nine is jaw dropping.Was playing Diablo 3 with my friend who has ryzen and a 1080 and my ryzen and rx 480 was getting double the fps about 70 vs 140. I get 70-90 FPS in crysis 1. Gallium-nine has just really impressed me. Even play CoD4 multiplayer online. I remember get nothing but graphical glitches and crashes in CoD 4 a handful of years ago. Come a long way.

It is great to see this in mainline finally, been a long time coming.

Many games are usable in actual wine, any games when minimum stay above 40fps is acceptable for most users yeah is dont ideal but is playable

And have support, in my case personally devs solved various bugs sended and many other bugs posted for other users

However nine is usefull in certain scenarios when have lower cpu for example case amd kabini - beema - mullins plataform or intel atom (gpu driver suck compared amd), in this case still dont have support is only way run games acceptable

Back to csmt dont be out until henri verbeet finish csmt work related

But in lastest releases more and more work are added, this reasons give to think about could be a little chance of csmt release

But no appear any definitive notice about that, until today when them surprised with this wine release, one day before regular release (normally appears friday)

^_^

Quoting: JudasIscariot
Quoting: ShmerlFinally. The Witcher 3 with 2.5 staging hasn't improved much (I just tested it). I'll wait for 2.6 staging to catch up for more tests.

If you end up testing Wine 2.6 before I do can you tell me if it's possible to toggle CSMT like you can in Wine Staging?

I just built Wine 2.6 with a few selected patches from staging. I don't see anything related to CSMT in Wine settings UI. So it might be supported, but should be configured manually for now I assume.

I just want to be able to toggle it somehow in case it affects a game's performance in a negative way...

Oh and thanks for the update :D

Also, Wine staging is using a special dll for that - wined3d-csmt.dll and using an override to toggle it. I can't find anything like that in Wine 2.6.

Still trying to figure out how CSMT is supposed to be configured there.

Well, according to this: https://source.winehq.org/git/wine.git/blob/HEAD:/dlls/wined3d/wined3d_main.c#l208

It should be in registry as csmt = enabled, in the same Direct3D place as other settings. But it doesn't work. It never outputs this in the log either:

Setting multithreaded command stream to ...

I guess I'm missing something.

Well that's weird, I am on Mint 17.3 (Ubuntu 14.04) and I got wine staging up to 2.4 but not 2.5 or 2.6. I notice that they change the repository. It is not a ppa but it is a repository ? I remove the ppa (http://ppa.launchpad.net/wine/wine-builds/ubuntu) and add the repo (not sure what the difference is) Still the Mint updater doesn't offer me anything. Any idea ? TX

Wine staging 2.5 was delayed a lot (the code was updated 4 days ago). Staging 2.6 isn't ready.
adamhm Apr 13, 2017
Unless they changed it with this release, enabling CSMT requires:

[HKEY_CURRENT_USER\Software\Wine\DllRedirects]
"wined3d"="wined3d-csmt.dll"
