Low frame rate. What to do?
This short tutorial explains the most common fix for low frame rate.
Frame rate is the term for how many frames per second (fps) the system records. The maximum frame rate for the Xbox Kinect sensor is 30 fps. We recommend a frame rate of 28 fps or more. If the frame rate is low on the calibration screen, then a red dot may appear and the system will not scan. This is to ensure good data collection.
The cause of a low frame rate is usually because of low processing power of the PC. We recommend an i7 quad core PC, with a dedicated graphics card (eg. Nvidia Gforce 900+).
Sometimes the internal graphics card (GPU) and the dedicated graphics card are in conflict, causing poorer performance and a drop in frame rate.
