For people who don’t know:

NTSYNC is a Linux kernel feature designed to help Windows programs run better on Linux, especially through compatibility layers like Wine or Proton (used in Steam).

NTSYNC puts Windows-style synchronization objects directly into the Linux kernel.

This means:

  1. Less emulation

  2. Faster performance (fewer context switches)

  3. Better compatibility for modern Windows apps and games

  4. Lower CPU overhead

Although in many of the tests I have seen, the performance was not actually better in general.

The main benefit so far seems to be not so much a synchronisation that performs better but one that works much more closely to how Windows does it natively thus helping some programs that don't work well with Wine.
