Initially, it was thought that the Xbox One Kinect sensor does not take any processing power from the console, but according to a recent interview that may not be the case. Microsoft said Xbox One will actually be able to make use of additional GPU power when the system does not have to accommodate Microsoft's voice and motion interface.
"Yes, the additional resources allow access to up to 10 percent additional GPU performance," a Microsoft rep recently told Eurogamer. "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."
There seems to be some confusion as to whether or not this particular GPU boost is specific to the new Kinect-less Xbox One SKU, but from the sounds of it, Microsoft is simply saying all Xbox One consoles will have a little more GPU to play with when Kinect isn't present. The company also mentioned plans to release a new SDK that will allow developers to tap into the additional GPU (which was previously reserved for Kinect). This follows up quite nicely with recent tweets from Xbox head Phil Spencer saying that additional GPU bandwidth will be made available in the future.
"In June we're releasing a new SDK making it possible for developers to access additional GPU resources previously reserved for Kinect and system functions…With this SDK, we will include new options for how developers can use the system reserve," Microsoft said.
It is nice to hear that Micrsoft is allowing developers to use the avialble GPU resources as they see fit as oppsed to reserving a cetain portion for its motion/voice technology. Hopefully we will see devs push the new console's technical capabilites even further with the new SDK.
