According to Dying Light developer Techland, Microsoft has recently updated the Xbox One SDK. This new updated SDK gives better control over Xbox One’s resources which lead to improved performance for games. Specifically, this update includes finer control over the Xbox One’s ESRAM (embedded static RAM).
“The main thing is just how much the ESRAM control has improved,” said Binkowski in an interview with GamingBolt. “The new API allows you to do a lot more with the ESRAM, things devs have always wanted to do but were not easily accessible. This together with better tools (PIX) allowed us to really improve performance and tweak ESRAM usage.”
Microsoft commented that they are committed to giving developers new tools and flexibility to make their Xbox One games even better.
