voice chat systems do not require any quantity of data to be established within half a millisecond. beamng calculates a complete physics frame every half a millisecond. read my words. --- Post updated --- high speeds of true data transfer only eliminate a very small amount of latency. we are currently very limited by the speed of electrons and photons through matter. it only hits about 2/3 the speed of light in most circumstances. even if you can send a lot of distinct signals in a given timeframe, they still take time to propagate. that delay alone, even ignoring processing and switching overhead, would make any kind of WAN play impossible.
