Disabling chromium vsync seems to have a big positive impact on perceived perfomances (aka input lag) in Open Stage Control.

I'd like to verify that.

Requirement

Having chromium v49+ installed

Desactiver le démarrage automatique de pulseaudio (pour un éssai temporaire, le tuer : killall pulseaudio -9) :

Editer ~/.config/pulse/client.conf ou /etc/pulse/client.conf et changer autospawn = yes en autospawn=no (décommenter la ligne en supprimant le ; si présent en début de ligne)
