Just camera movements and your mouse movement ? Like normal recordings ? No . I can ' t speak about how League would have to do it specifically since God only knows how it ' s being programmed , but most games just have it record the commands sent to the server and reproduce it in the replay . Since the server already has the commands in order to build the replay , watching from a certain perspective doesn ' t require holding onto much , if any , more data . Camera positioning would likely be the only thing they would have to add on , if that . <| sep |> South African groups had cattle before Europeans arrived in South Africa . Even the Khoisan , who were more primitive than many other groups in SubSaharan Africa , herded cattle . When the Dutch first arrived at the Cape in 1652 , they found the Khoisan herding cattle . The Nguni groups located farther east also herded their own cattle prior to European colonization .
