Not 100% sure if it's even intended to be changed, but even with all settings to true in factorio v2.0.13 there are still effects playing on the ground where lightning hits. After digging into the code, it's because of graphics_set.ground_streamers not being set to nil.

And if it's not a bug and you didn't intend to remove that, may still be nice to also have a setting to disable for those who want these effects gone too.

Also, thanks for this mod. The first thing after coming to Fulgora looked for a mod exactly like this because can't handle the lightning, and was glad to see someone made a mod already!

Also, realized that even with this setting there are still explosions playing ( graphics_set.explosion ) and even with those disabled, there are still some minor effects too. Those don't bother me personally much but yeah.

New version adds options for all of these to make the strikes invisible.
The original requirements where for YT and twitch streaming compression concerns.

Thank you!
