Summary
Creating a simple vector3 object is significantly slower than creating a tuple(float,float,float). This unexpected cost has major runtime impact when vector creation appears in tight loops.

Steps to Reproduce
Call this every frame
Vector benchmark
for (i := 0..10000):
v := vector3{X := 1.0, Y := 2.0, Z :=3.0}
Tuple benchmark
for (i := 0..10000):
t := (i, i, i)
Expected Result
Both benchmarks should require approximately the same execution time.
Observed Result
Actually, the Vector3 benchmark causes the tick rate to drop to an average of 3 to 4 ticks per second. The tuple benchmark maintains a tick rate of about 30 ticks per second.
