What is NTSync?

• NTSync is a new Linux kernel driver merged in Linux kernel 6.14 that improves Windows gaming performance on Linux through Wine/Proton.

• It works by handling Windows NT-style thread synchronization directly at the kernel level, replacing older user-space methods like esync and fsync with a faster and more accurate implementation.

• This greatly reduces CPU overhead and improves thread communication in heavily multi-threaded and CPU-bound games.

• As a result, some games can see FPS improvements ranging from 50% to over 150%, with certain titles gaining even more depending on the workload.

In short:

NTSync helps Windows games run significantly faster and smoother on Linux/Android.

Important Note:

Since, it's backported you might want to use this module to fix SELinux policy so that it can utilize NTSYNC.
