I analysed the Google Stadia demo video frame by frame to measure the input lag. I checked how many frames are in-between the moment when mouse starts moving and the camera on the screen begins to move. According to my calculations the demo lag on their cheap PC was about 60 milliseconds. This is a decent result, comparable with some of the HDTVs, but not good enough for pro gamers. In the video I explain how I measured this.
