ntsync driver to handle Windows locking types enabling Wine to work much better on many workloads (i.e. games). The driver framework was in 6.13, but now it’s enabled and fully working properly. Should make many SteamOS users happy. Even comes with tests!
Helps all of wine:
I wonder how much improvements is it going to bring to Proton, though. I don’t remember the last time I ran a game on pure WINE.
If I understand correctly, very little. Since proton already implemeted esync, which was a workaround for this.
Proton is mostly just wine and esync has been replaced by fsync a while back. Ntsync is another even faster/better sync mechanism.
