One of my biggest problems with XCOM 2, specifically the Avenger Defense mission, is the enemy corpses. When you save a game, and reload it, it saves the position of all the corpses, so corpses don't disappear at all. If you're like me, and you use the Avenger Defense mission as a way to fully promote your squad, once you get to 50 enemies killed it starts lagging hard, due to the amount of corpses on screen.
What setting do I need to tweak in the .ini files to remove corpses? This is getting fairly annoying as I have had to force evac when my team was healthy enough to continue the fight, but my computer couldn't stand it anymore.
