Question Any decal solution (Bullet holes) that does not take 40-50 fps on idle?

Found the issue, its related to having idling particle systems alongside the projectors, even if the particle systems arent playing (which we can't understand either). As soon as we disable the particle systems, issue is gone. If they are active (even if not playing and more than 1000 meters away outside camera view and far plane clipping) it takes a huge toll on fps, which is heavily magnified when camera looks near 0,0,0 point of world space (strange since theres no particle prefab in there)
