I just wanted to try out the overlay so I downloaded the beta. When I got the session started the data showed up on the control panel page. Somehow I could't select things like 'Timing' or 'Tower'. I could active 'Race update box' but I haven't seen anything from it. The only thing that is working is switching cameras via the web page. So is there more I need to do then to download the beta, get in a session and view the fullscreen replay to see the overlay like in those e-sport events ?
