LO,
I'm not arguing the processing power of PC or the game code itself, but as CourtneyM (IMO correctly) noted, level of detail and the value of input alone.
Maybe I'm too conservative, but ID-ing fighter's radar at 290nm in the cluster**** of EW going on all over the place while the guy is just pinging the space in RWS, is a bit SciFi to me.
But as I said, I may be completely wrong here and modern RWRs are indeed sensitive and powerful enough (as in PRF/modulation separation) to do that.
