Does anyone know how well / poorly this mod does for game performance? It seems like for me, this mod drops my framerate noticably. I don't have any FPS-measuring tools set up yet, but it feels like it drops from the game running at 30+ (I'm old, I don't need 60 or 120) down to something like 10 FPS. It seems to happen on maps with radioactive waste, and even more-so on maps with lava, which are both things that add lights/lighting to the map.
