      No, it was in the buildup for Unreal Tournament 2004 IIRC, definitely wasn't in the 90's : Toraz Chryx

  The problem is this. Or, maybe it is better to say: The reason we haven't been seeing more of this is:
  
  Devs have to figure out what to spend spare CPU and GPU cycles on.
  
  Take the Unreal distortable rocket smoke trails, for example.
  I bet someone said: We can do that OR we can improve the [AI terrain cover analysis] / [sound doppler-ific-ation doo-hickey-ness].
  
  Then the devs and and the project leads meet and discuss the options. The conversation probably goes something like this:
  
  "The smoke distortion thing is really cool"
  "Ya, but it's the kind of thing you see once or twice and then just focus on the battle"
  "But if the AI is a bit smarter, that will really be noticed. At every given moment"
  "Ok... Ya. Lets go with that, then"
