Atrdriver:
It simply doubles the values of maximum particles drawn on screen , from 512 to 1024. It's not a big think in fact, but by raising the value with ini provided or by (even better) doing it yourself, you are sure , everything looks ok -I use a lot of SCATTER type emitters in my packs, which are spawning a lot of particles.
But generally you don't loose anything.
Mad Mike:
yes, but as for tactical ground explosuin I'm not satisfied with it right now. However, aerial nuke explosion for Genie is ready, but being a part of someelses project, I was asked not to release it until that work is complete (or can I Saganuay?) A hint for you would be to look inside my personal album
