I meant to assume 5ms CPU time: 12 input + 5 processing + 15 output = 32. Add 5 for network round-trip to get 37.
> 5ms roundtrip
5 ms network round-trip or less is common in offices or homes with fiber. Here's ICMP ping 1.1.1.1 from my office just now:
rtt min/avg/max/mdev = 4.075/4.700/6.407/0.459 ms. (UDP wouldn't be so different.) Of course, on wifi or low-speed broadband it wouldn't be so fast.
> high latency TVs
High-latency displays makes network latency less noticeable relative to a conventional console game (but more noticeable relative to a PC game on a fast-updating screen).
