It's audio and haptics that stand to benefit the most from an RT-patch kernel, not video. While the difference between a 1ms and 8ms response will be nil as far as video is concerned... it's not unreasonable that some people will hear/feel the difference.

Also, in practice the scheduler for the RT-patch kernel is a little more reliable for SCHED_FIFO threads/processes. This allows them to run smaller rendering buffers without fear that the buffer will under-run because they didn't get scheduled at the right time.

You can get "good" results with a vanilla kernel (in practice, around 20ms). With an RT-patch you can potentially get "better." Most probably won't notice the difference, but some might.
