I made a particularly intense test map with no scripting. Dozens of fighters, numerous destroyers (of which are my Lightning Destroyers), big battles, and most of all, lots of projectiles. Every time I start this mission, whenever I fire I hear the sound, see the muzzle flash, but no projectile. Even missiles have the same problem, they don't shoot! This kills gameplay because I shoot but the game doesn't register a shot or a hit. I could spend several minutes chasing down a fighter shooting my guns like crazy and still be chasing him to no avail. Is there some kind of projectile limit built into FS2? If so, it means big trouble for my mod as lots of ships and high rate of fires is some of the smaller yet still a strong defining point in my gameplay.
To set the atmosphere:
My Lightning Destroyers have around 40 turrets. 4 of which are missile launchers that swarm 12 missiles every second (yep, lots), 1 giant missile every 15 seconds, the rest are plasma turrets with varying firing rates (mostly very high ROF). And there are 4 of them on the map.
My basic (human) fighters have a very high ROF cycling weapon similar to the Subach but faster. My heavier fighters have 8 fire points for this weapon and seriously shoot LOTS of bolts.
There are several enemy destroyers with primarily beam weapons that don't seem to be hampered by the cap if there is one. The enemy fighters use small, relatively average beam cannons with a reasonable rate of fire and swarm missiles.
Because the enemie's weapons are unhindered I get creamed most of the time because I can't kill them if my weapons don't shoot.
