Explosion SFX arent culled outside the map

Other stuff like missles and airplanes can also leave and reenter the map.
It would be a bit strange if an airplane outside the map takes fire by flak but you don't notice because you can not see the explosions...

thats different, but why should the ground glow outside the map?

I think its actually good that gfx aren't culled. It provides a sense of a wider world. Plus culling gfx would look really weird (imagine Argh's nuke detonating at the edge of a map)
