Gamers, attention\u00a0: Windows\u00a011 r\u00e9duit drastiquement les performances des PC sur lequel il est install\u00e9. Le coupable est le VBS, une fonctionnalit\u00e9 de s\u00e9curit\u00e9 activ\u00e9e par d\u00e9faut qui cr\u00e9e une zone de m\u00e9moire \u00e0 l\u2019abri des attaques. Seuls les futurs PC tournant nativement sur le syst\u00e8me d\u2019exploitation sont touch\u00e9s.<\/strong><\/p>\n

\"Windows<\/p>\n

\u00ab\u2009Si vous jouez aux jeux vid\u00e9os, Windows 11 est fait pour vous\u2009\u00bb.<\/em> Cette annonce de Microsoft a de quoi rassurer les gamers quant aux performances du syst\u00e8me d\u2019exploitation. Pourtant, \u00e0 seulement quelques jours du lancement officiel<\/strong> et alors que l\u2019\u00e9diteur corrige les derniers bugs<\/a>, nos confr\u00e8res de PC Gamer ont fait une d\u00e9couverte pour le moins embarrassante. Windows\u00a011 fait baisser les performances graphiques de 25\u00a0%<\/strong> en moyenne par rapport \u00e0 son pr\u00e9d\u00e9cesseur. Il n\u2019est ici nullement question de pilotes des GPU, les constructeurs les ayant d\u00e9j\u00e0 rendus disponibles au t\u00e9l\u00e9chargement<\/a>.<\/p>\n

Le coupable est le VBS, ou la s\u00e9curit\u00e9 bas\u00e9e sur la virtualisation<\/strong>. Voici comment Microsoft d\u00e9crit cette fonctionnalit\u00e9\u00a0: \u00ab\u2009VBS utilise les fonctions de virtualisation mat\u00e9rielle pour cr\u00e9er et isoler une r\u00e9gion de m\u00e9moire s\u00e9curis\u00e9e du syst\u00e8me d\u2019exploitation normal. Windows peut utiliser ce \u201cmode s\u00e9curis\u00e9 virtuel\u201d pour h\u00e9berger un certain nombre de solutions de s\u00e9curit\u00e9, leur offrant une protection consid\u00e9rablement accrue contre les vuln\u00e9rabilit\u00e9s du syst\u00e8me d\u2019exploitation, et emp\u00eachant l\u2019utilisation d\u2019exploits malveillants qui tentent de d\u00e9jouer les protections\u2009\u00bb<\/em>.<\/p>\n
