this expression, what does it means? |
'Metal' refers to the hardware itself. The closer to the metal you're coding (which is usually the result of either API optimization, or if someone is really dedicated they can code directly to the hardware with something like assembly), the more of the hardware's power and quirks you can take advantage off.
It's one of the reasons why consoles tend to produce better results than a PC with comparable hardware. Programming for a specific piece of hardware (rather than thousands of PC combinations) let's you code closer to the metal.
TL;DR - Closer to the metal = more optimization potential.
