L'entreprise Feral Interactive a publi\u00e9<\/a><\/noindex> a publi\u00e9 un optimiseur GameMode 1.5<\/a><\/noindex>, impl\u00e9ment\u00e9 sous forme de processus en arri\u00e8re-plan, modifiant \u00e0 la vol\u00e9e divers param\u00e8tres syst\u00e8me Linux pour atteindre des performances optimales des applications de jeu. Le code du projet est \u00e9crit en C et est fourni<\/a><\/noindex> sous licence BSD.<\/p>\n

Pour les jeux, il est recommand\u00e9 d'utiliser la biblioth\u00e8que sp\u00e9ciale libgamemode, qui permet de demander des optimisations sp\u00e9cifiques, non appliqu\u00e9es par d\u00e9faut dans le syst\u00e8me, pendant l'ex\u00e9cution du jeu. Une variante de la biblioth\u00e8que est \u00e9galement disponible pour ex\u00e9cuter le jeu en mode d'optimisation automatique (chargement de libgamemodeauto.so via LD_PRELOAD lors du lancement du jeu), sans n\u00e9cessiter de modifications du code du jeu. L'activation des optimisations peut \u00eatre contr\u00f4l\u00e9e via un fichier de configuration.<\/p>\n

Par exemple, avec GameMode, il est possible de d\u00e9sactiver les modes d'\u00e9conomie d'\u00e9nergie, de modifier les param\u00e8tres de distribution des ressources et de planification des t\u00e2ches (CPU governor et SCHED_ISO), de r\u00e9organiser les priorit\u00e9s d'entr\u00e9e\/sortie, de bloquer le d\u00e9marrage de l'\u00e9conomiseur d'\u00e9cran, d'activer divers modes de performances am\u00e9lior\u00e9es sur les GPU NVIDIA et AMD, et de proc\u00e9der \u00e0 l'overclocking des GPU NVIDIA, ainsi que de lancer des scripts avec des optimisations d\u00e9finies par l'utilisateur. <\/p>\n

dans la version 1.5, il a \u00e9t\u00e9 ajout\u00e9 la possibilit\u00e9<\/a><\/noindex> Changement dynamique du r\u00e9gulateur de modes CPU (CPU governor) pour les processeurs Intel avec GPU int\u00e9gr\u00e9, si l'utilisation du mode \u00ab performance \u00bb entra\u00eene une baisse des performances du syst\u00e8me graphique sous forte charge GPU. Dans ce cas, le passage au mode \u00ab powersave \u00bb permet de r\u00e9duire la consommation d'\u00e9nergie du CPU et de lib\u00e9rer plus de ressources pour le GPU (le CPU et le GPU partagent un budget d'alimentation commun, et une allocation prioritaire des ressources au CPU entra\u00eene une r\u00e9duction de la fr\u00e9quence du GPU). Sur le CPU i7-1065G7, l'optimisation propos\u00e9e permet d'augmenter les performances du jeu Shadow of the Tomb Raider de 25 \u00e0 30%. <\/p>\n

GameMode 1.5 pr\u00e9sente \u00e9galement un nouvel ensemble d'API D-Bus, utilisant le m\u00e9canisme 'pidfd' pour traiter les situations de r\u00e9utilisation des PID (pidfd est li\u00e9 \u00e0 un processus sp\u00e9cifique et ne change pas, tandis que le PID peut \u00eatre li\u00e9 \u00e0 un autre processus apr\u00e8s l'ach\u00e8vement du processus actuel associ\u00e9 \u00e0 ce PID). <\/p>\n
