Funny story, my C++ class is less than half as quick as its BP equivalent...

Just as a general tip, you most likely don’t want to put function calls inside of a code that is iterative.

void ATestFish::Tick( float DeltaTime )
{
	Super::Tick( DeltaTime );
	if (**ProjectileMovement->Velocity.Size()** <= 0.f)
	{
		ProjectileMovement->SetVelocityInLocalSpace(FVector(200.f, 0.f, 0.f));
	}
}

The Tick function calls that Velocity.Size() method every second. It’s as inefficient as this code:

vector<double> vec{1.3,34.3,0.2,12...........};  // suppose vec size is 10000

for(int i=0; i<vec.size(); i++)
{
     // process the vector element vec*
}

which can be optimized in

vector<double> vec{1.3,34.3,0.2,12...........};  // suppose vec size is 10000

size_t size = vec.size();

for(int i=0; i<size; i++)
{
     // process the vector element vec*
}

I see what you mean but I don’t believe it’s quite the same thing here.

I’m doing this because the velocity changes every tick. and it’s an if so it executes once (as far as my understanding goes)
