I was watching this video, comparing Insurgency weapons and COD weapons.

One small detail that seems so simple but it adds something cool: The smoke spray out of the gun barrel when shooting.

It add a feeling the weapon is more powerful. Its a simple thing but its so cool.

i'd like to see this as more of an option.

perhaps have a slider for "gun barrel smoke effect"

It's a little excessive honestly. Sandstorm feels more realistic. The only difference is in real life if you fire a bunch of rounds without moving the gun much the smoke can build up around you making it thicker and more obvious, and in some cases leading to the occasional really big muzzle flash.
