Microsoft is releasing an updated Xbox One SDK for developers this month which will give developers access to more GPU bandwidth, so more performance for their games. Also there are new tools and flexibility to make games better. Xbox chief Phil Spencer tweeted this information yesterday. During the launch of Xbox One, Microsoft said that they are reserving about 10% of the GPU for Kinect and other system process. But this update for SDK is making it possible for developers to access additional GPU resources previously reserved for Kinect and system functions. Microsoft commented the following regarding the new SDK release,
The additional resources allow access to up to 10 percent additional GPU performance. We’re committed to giving developers new tools and flexibility to make their Xbox One games even better by giving them the option to use the GPU reserve in whatever way is best for them and their games. The extra GPU will add to games’ performance and definition, but it is up to developers to choose how they want to utilize the extra GPU performance.
Microsoft also confirmed that they will include new options for how developers can use the system reserve as well as more flexibility in our natural user interface reserve (voice and gesture). This means that developers with Games which doesn’t need any Kinect functionality can use more CPU/GPU than other games.
