Wine is the windows compatibility layer that Proton is based on, which is how the Deck plays windows games. So any significant update to wine will directly benefit windows games on Deck, as soon as Proton is updated.
NTsync is the headlining new addition to Wine11. It replaces Esync and Fsync as a much accurate synchronizer. This should:
-
Make games run smoother, removing microstutters and improving frame pacing
-
Significantly improve performance in some older games that could run into major performance bottlenecks from this. You can see some fps increases here, with many of the affected games getting over twice the fps.
NTsync requires kernel support, but Valve added that in steamOS 3.7.20. Wine11’s NTsync hasn’t made it into Proton experimental yet, but GE-Proton has added support for it already, so it’s not hard to try it out.
Wine11 also improves support for older 32 and 16 bit windows applications.



From the email;
The gain in performance varies wildly depending on the application in question and the user’s hardware. For some games NT synchronization is not a bottleneck and no change can be observed, but for others frame rate improvements of 50 to 150 percent are not atypical. The following table lists frame rate measurements from a variety of games on a variety of hardware, taken by users Dmitry Skvortsov, FuzzyQuils, OnMars, and myself:
The whole thing is worth a read to see how this works, but jumps from 110 fps to 860 fps is just insane. The wine team has done some really great shit with this.
An important note is that this is compared to base wine, not Proton with Esync/Fsync.
There may have still been significant gains, since those were some of the games worst affected by the lack of proper sync, but someone would need to run more benchmarks to find out.
Yeah. This whole results thing isn’t really a well-structered article like you might get from a real journalist, so much as a quick and dirty comparison for examples sake in a software update push.
Please
foxfix that terrible formatting :pEdit: as context, op’s original post had formatting that was all over the place haha
Anything for you boo 😘
Make sure to fix your fox typo too.
Ok, that was freaky. My girlfriend calls me boo, and with the kiss emoji i was freaking out for a while hahaha
