It's a long technical read but gives a little insight to what going on inside of the X1. It amazing the X1 reserves 10% for non graphics reasons. But as the system drivers matures those will be released. It rumored Turn 10 as a 1st party dev have had access to these drivers before anybody else and that's why Forza 5 looks so damn good at 1080p/60fps.
Xbox One reserves 10 per cent of graphics resources for Kinect and apps functionality, Digital Foundry can confirm, with Microsoft planning to open up this additional GPU power for game development in the future. This, and further graphics and performance-based information was revealed during our lengthy discussions with two of the architects behindthe Xbox One silicon.
"Xbox One has a conservative 10 per cent time-sliced reservation on the GPU for system processing. This is used both for the GPGPU processing for Kinect and for the rendering of concurrent system content such as snap mode," Microsoft technical fellow Andrew Goossen told us.
"The current reservation provides strong isolation between the title and the system and simplifies game development - strong isolation means that the system workloads, which are variable, won't perturb the performance of the game rendering. In the future, we plan to open up more options to developers to access this GPU reservation time while maintaining full system functionality.
