In most cases a resolution of 320×240 is sufficient, this is capable of producing a much higher sub pixel resolution, enough to allow accurate cursor control on a high-resolution monitor. Resolutions 640×480 and above have diminishing returns and correspond to an exponential increase in CPU usage when not sufficiently compressed before reaching the computer. Higher resolutions become more important at greater distance from the camera.
The Wii utilizes a low-resolution 128×96 sensor, which is found by some to produce jittery tracking and may require smoothing to improve stability at the cost of decreased responsiveness.
