La premi\u00e8re Preview de Windows 11 introduit un syst\u00e8me qui ajuste dynamiquement le taux de rafra\u00eechissement de l'\u00e9cran des PC portables pour \u00e9conomiser la batterie sans que cela n'impacte l'exp\u00e9rience utilisateur. Une fonctionnalit\u00e9 baptis\u00e9e “Dynamic Refresh Rate” (ou DRR).\u00a0<\/strong><\/p>\n

\"Windows<\/p>\n

Si vous poss\u00e9dez un PC r\u00e9cent, il y a de fortes chances pour que son \u00e9cran soit compatible avec des taux de rafra\u00eechissement tr\u00e8s \u00e9lev\u00e9s – 120 Hz, 240 Hz<\/strong>, voire m\u00eame davantage. Il faut le voir en conditions r\u00e9elles pour s'en rendre compte, mais doubler, voire quadrupler le taux de rafra\u00eechissement d'un \u00e9cran permet de fluidifier les animations, le d\u00e9filement et les graphismes dans les jeux vid\u00e9o<\/strong> – au point que toutes les actions de l'utilisateur d\u00e9livrent une \u00e9tonnante sensation de r\u00e9alisme.<\/p>\n

Mais ces \u00e9crans ont aussi un inconv\u00e9nient : lorsqu'ils sont configur\u00e9s pour un taux de rafra\u00eechissement \u00e9lev\u00e9, ils consomment nettement plus d'\u00e9nergie<\/strong>. D'autant qu'\u00e0 cela s'ajoute une sollicitation plus intense du GPU, r\u00e9duisant de beaucoup l'autonomie de la machine. C'est pourquoi Microsoft annonce dans un billet de blog le lancement de la fonction “Dynamic Refresh Rate” (DRR)<\/strong> dans Windows 11<\/a>.<\/p>\n
