We measured SPUD's response time as less than 1 millisecond by taking a picture simultaneously on the SPUD prototype and a laptop (with a timer duplicated on both screens). SPUD was connected via HDMI for the test. With a wireless adapter (i.e. Chromecast), response time will be bottlenecked by the latency of the wireless adapter. In short, SPUD is good enough for all applications including gaming response-wise!
