Hmm, yeah. Some other people have reported that as well. In case you're curious, it's not any of the lighting effects, those have a really tiny time-complexity growth rate. It's likely just the models themselves, the pipeline for rendering those are not well optimized yet so they can kill the game's framerate if there are too many of them within the player's field of view. Don't worry, we're working on it though.

In other news: we finally got featured in another publication today! And twitch.tv is going to be live-streaming some gameplay, too. Talk about awesome!
