I have been wondering with some of the damage spells that are out there, does subtle spell make it seem like spells like scorching ray, fireball, or magic missile seem to come out of nowhere as well? It isn't clear if they would be evidently coming from you or out of nowhere. 

NVM I figured it out:

Perceiving a Caster at Work

Many spells create obvious effects: explosions of fire, walls of ice, teleportation, and the like. Other spells, such as charm person, display no visible, audible, or otherwise perceptible sign of their effects, and could easily go unnoticed by someone unaffected by them. As noted in the Player’s Handbook, you normally don’t know that a spell has been cast unless the spell produces a noticeable effect.

But what about the act of casting a spell? Is it possible for someone to perceive that a spell is being cast in their presence? To be perceptible, the casting of a spell must involve a verbal, somatic, or material component. The form of a material component doesn’t matter for the purposes of perception, whether it’s an object specified in the spell’s description, a component pouch, or a spellcasting focus.

If the need for a spell’s components has been removed by a special ability, such as the sorcerer’s Subtle Spell feature or the Innate Spellcasting trait possessed by many creatures, the casting of the spell is imperceptible. If an imperceptible casting produces a perceptible effect, it’s normally impossible to determine who cast the spell in the absence of other evidence.

A spell with a material component will still be a giveaway for subtle spell. And even if it didn't, when something fires from the caster toward a target, people are going to know where it came from. Maybe they won't be able to react in time to counterspell it, but it ought to be pretty obvious.
