I'll look into adding some settings - I'm not gonna be too thorough with giving options (particularly as doing so may influence performance), but I'd happily give it a shot. Yeah, the mod has gone through a LOT of performance enhancements, and it's close to as good as it can be (I think). I might look into even more (or at least some settings to enable aggressive performance enhancements), but the game engine isn't really built for this, so I'm pushing it anyway.
Yeah, there are probably still some bugs with projectile ranges - Factorio is super inconsistent with how you define the range, so its not really surprising that some cases slipped through. I don't mind doing it on this thread, or another if you want. I'm pretty chill with how issues are organized.
True Nukes/Warheads probably aren't good examples of what most mods look like - the pre-0.3 version should be more 'normal', as 0.3 I moved to a pretty eccentric system of auto-generating the weapons (using Warheads), since I couldn't keep up myself anymore. Glad you like it!
