dps wise? hell nah shotgun is way higher but rifles are very economic in terms of ammo, up to the player to choose if you want to make profit or go full on dps
got the usual for guns hunter, marksman, quickshot, head hunter, reloading, rifle expert and aim for the heart aside from those ones im running sprinter, jogger, kickboxing, looter, and toughness
i have mine on texture and shader on high shadows disabled everything else off except for v-sync, hud, remove bodies, anti-aliasing, lightning, deferred rendering and blood effects
