Questions about fsync (in the context of playing games)

[keybreak]

Here’s quick tl;dr from my Linux gaming guide:

1. It’s not universal improvement, depending on a game it may vary, but generally speaking very modern multi-core capable games can benefit significantly.

2. You’d need Kernel ready for Fsync, in case of Arch it’s:

   • zen
   • @anon31687413’s Kernel linux-vd have this patch
   • You can patch any Kernel yourself (for a patch ask @anon31687413 he knows it best)

3. To enable Fsync you also need a special version of Wine capable of that:

   • TKG
   • Manually patched Wine build

4. Finally you can just enable it in Lutris if all conditions met

   Select game, Right Button -> Configure

   Runner options tab:

   Enable Fsync - same as Esync, should be better, but Engine and Kernel must support it!
   Lutris will alert you if it’s not supported by Engine in use

Also i think you need to disable Esync then, coz they effectively cancel each other and Fsync is more performant, but little less compatible for now
