Doing that improved performance for Windows apps on Linux when using Wine or Valve’s Proton that is based on the former. […] benchmarks that show games running better with average improvement rates ranging from 50% to 150% when using the new driver compared to not using it.

Talking about improvements for Wine and Proton then providing no actual data for Proton (which is already using a completely different mthod for syncs - yes the basic wine method sucks) is stupid.

I believe this replaces esync and fsync. IIRC it’s slightly faster and has the benefit of being mainlined.
