Au niveau optimisation, j'ai gagné 500 increment counter facilement. Je commence à comprendre que je code comme un porc en ASM et je vais m'habituer à optimiser mon code dès son écriture.

}Mais le 67%, il signifie quoi ? 67% de quoi ?Ca signifie que 67% du temps initial est disponible pour exécuter ton propre code. En gros, ta TI aura 67% de sa vitesse pendant que le son est joué.
Parce que le CPU il est tout le temps utilisé.Le CPU est tout le temps utilisé, mais parfois à rien faire. Donc c'est ce temps passé à attendre que l'on calcule.

plutôt qu'en pixels.
Regarde mon post, t'as la solution.
j'avais essayé de la faire assez simple pour qu'elle soit facilement compréhensible
Moi j'avais pensé utiliser ta lib pour C&C (projet V4pOR T34m pas avant 2048)
