Ntsync x Fsync on Wayland - 5 games comparison
(www.youtube.com)
Fsync hasn't been dropped from the kernel, 6.15 still supports it, this test was done on 6.15.
I did a very quick and dirty test here and it appears to be still slower than fsync by about 10 ~ 12%, I'll test it better later.
Brasil, the name comes from Pau Brasil, a tree that has a deep red color, used to make dye and for its quite beautiful red wood. The word Brasil comes from brasa (ember), essentially means "tree that's red like an ember".
