traduction en bref :
We have delayed the PC version of Naval Strike because we are concerned that the combination of the pack and planned PC updates would increase performance issues on mid-range to high-end PCs.
we have decided to delay the Xbox One version of Naval Strike because we want to address issues in the animation system that hinder players from engaging targets in set circumstances using popular weapon configurations.
la combination du DLC naval strike ainsi que la nouvelle mise á jour augmenterait les problemes de performance pour les ordinateurs ( on mid-range to high-end PCs )
pour la ONE il sagirait d'un bug ( LoL
) d'animation qui qui gêne les joueurs d'engager des cibles ou objectifs utilisant des configurations d'arme populaires.
We are trying to resolve these problems as quickly as possible and hope to release the update in early April for Xbox One and PC ---> sortie prevu debut AVRIL
We also want to remind Xbox One and PC owners of Battlefield 4 Premium that they will have two weeks early access for Naval Strike once it’s released. Thanks for your continued patience and passion for our games.
bref les non premium sur PC et ONE devront attendre 2 semaine apres LOL... soit 3 a 4 semaine apres les premium ps4,ps3 et xbox360
