BG-09, you start your post saying as though stuff to do with explosions is going to happen and how much detail it will have etc, then you ask if it is going to happen.

Have I missed an annoucement about the explosion physics? or are you asking for these details, cos it sounds like its way beyond what is currently possible for the average pc.

A stick of 6 500lb bombs all exploding with the extended physics particals you are talking about would bring most average pc's to their knees surely?
