What is anti-sync (tsync) in Wine 11?
Anti-sync is Wine's kernel-level implementation for Windows synchronization primitives. Wine 11 uses a new kernel driver that models the Windows sync API and exposes a /dev/tsync device so Wine can coordinate threads more accurately than previous workarounds like esync/fsync.
How big are the real-world performance gains with Wine 11?
Gains vary by game, but some heavily multi-threaded titles show dramatic increases — Dirt 3 reportedly jumped from ~110 fps to ~860 fps, Tiny Tina's Wonderlands from ~130 to ~360 fps, and previously unplayable games (e.g., Call of Duty: Black Ops 1) became playable.
Do mainstream Linux distributions need special builds to get these benefits?
No — the tsync changes have been merged into the mainline Linux kernel (starting around version 6.14), so mainstream distro users won't generally need custom kernels to benefit.
What does Wine 11's WoW64 implementation do?
Wine 11 includes a complete WoW64 implementation, allowing 32-bit (and some 16-bit) Windows applications to run on 64-bit Linux systems without requiring multi-lib packages.
Will Wine 11 make all games faster on Linux?
Not all games will see meaningful improvements. Many titles will be unaffected or see small changes, but heavily multi-threaded games that rely on Windows sync primitives can see large performance boosts.
