Explanation: Winesync is yet another reimplementation of the NT synchronization primitives for Wine, this time using a new kernel module instead of using existing kernel features or a new syscall. This implementation mimics the original from Windows perfectly (bar any bugs), in contrast to esync and fsync which had some hackily implemented operations. Performance shouldn't be much different from esync and fsync.

For those who haven't found out themselves yet I think everyones moving to this instead now:

I can't seem to get this to work, I'm guessing I need a patched version of wine or proton to use this? And I read somewhere TKG doesn't include it anymore?

Does Proton GE support it?

Information about how to use this is extremely scarce...

Looks like the site is back online.

Same issue here, source URL is inaccessible (

Thanks again for this and making it (much!) easier to get working on Arch Linux. I finally got bit further with this. I started using wine-tkg (self-built) instead of wine-ge-custom which has enabled me to enable winesync in wine.

Everything works great with the module but not the udev rule for some reason? Its installed but I still have to manually chmod /dev/winesync before launching wine.

I am wondering if the winesync module is coming up later than when udev runs or something odd...

More details:

$ sudo udevadm test /dev/winesync

Edit: Running:

modprobe winesync

makes everything just work.... could the solution be to add a file to '/etc/modules-load.d/' or ideally '/usr/lib/modules-load.d/' in the package? or should wine be starting this module when it launches? (it doesn't).

Yeah you are right - something weird happened. I've not even heard of winesync for two years but I think I cloned 'winesync-dkms' last time although I'm not sure why it would cause that since it looks like a clone.


I've re-cloned and its built fine with the correct version. Apologies for the noise

openglfreak commented on 2023-02-25 18:03 (UTC)

@rlees85 You haven't updated your clone of this package in almost two years, please build an up-to-date version of the package.

Seems broken...

Wondering if it works with wine-ge but I am happy to find that out myself once it is possible to build it

@Hakkaten: You will need a version of wine that actually supports it and I don't think many actually do. Infact I'm finding little conclusive information online - you'd probably need to build wine yourself to take advantage of it. If you read this though you can see if or not your version of Wine is actually using it:

Hakkaten commented on 2023-01-15 16:45 (UTC)

Is having this installed all I need to do to make use of it? Will any Wine on my system take advantage of this without any tweaking on my part? Just discovered this when I was browsing wine packages, I use CachyOS and their repos have this.

saghm commented on 2022-02-15 17:41 (UTC)

I've confirmed that the issue I was having was with the xanmod-rog kernel and not a winesync issue. Sorry about the noise!
