Realtime has nothing to do with 'nice'. With 'nice' you set the process' time-slice so that it gets more (or less) processor-time. With realtime ("soft" or "hard" realtime - there's a difference) the process is "guaranteed" to have processor-time within certain time-limits, something which "normal" schedulers don't do.
