Kinect features are dictated by firmware so that they can be added and upgraded over time.
The depth sensor used by Kinect is also dictated by firmware â€“ it is currently set at a 30 frames per second limit and a 320x240 resolution limit.
At a 640x480 resolution, however, Kinect could begin to detect fingers and hand rotation â€“ an effective quadrupling of its accuracy.
The issue relates to the USB controller interface, Eurogamer was told. It is capable of around 35MB/s, but it only uses around 15/16MB/s.
Figured it was a software thing they're specifically talking about, but it also has to do with gaming hardware, so it could fit in any section. Move if necessary.
