Wine 11 is a landmark release for Linux gaming, headlined by NTSYNC support — a new kernel-level driver merged into Linux 6.14 that correctly implements Windows NT synchronization primitives for the first time. Unlike previous workarounds (esync, fsync), NTSYNC runs in the kernel itself, eliminating wineserver round-trips and delivering dramatic performance gains: Dirt 3 jumped from 110 FPS to 860 FPS in benchmarks. The WoW64 architecture overhaul is also complete, removing the need for 32-bit system libraries to run 32-bit Windows apps. Additional improvements include a more capable Wayland driver with clipboard and drag-and-drop support, Vulkan 1.4, hardware-accelerated H.264 video decoding, and compatibility fixes for dozens of games. Valve has already added NTSYNC to SteamOS 3.7.20 beta, and all Proton-based setups will benefit once Proton rebases on Wine 11.

Wine 11 rewrites how Linux runs Windows games at the kernel level, and the speed gains are massive

The article claims massive improvements compared to baseline, but notes and explains in depth that in the meantime workarounds existed called fsync and esync.
I dont know if these workarounds were activated if one used steam or lutris. Because it also states that if you had fsync enabled, then this massive performance improvements would not be as notable.
I hope this is actually good news and not just hype about something that does not translate into the real world.
